WEBVTT 00:00:00.000 --> 00:00:03.299 Welcome to The Deep Dive. Today, we're tackling 00:00:03.299 --> 00:00:05.459 something that really blends intricate mechanics 00:00:05.459 --> 00:00:08.439 with some quite complex decision making. It's 00:00:08.439 --> 00:00:10.619 the kind of puzzle, I think, that resonates whether 00:00:10.619 --> 00:00:14.640 you're building a product, managing a team, or, 00:00:14.660 --> 00:00:16.480 well, in this case, dealing with a broken bone. 00:00:17.000 --> 00:00:19.620 We're diving into proximal humorous fractures, 00:00:19.820 --> 00:00:21.960 often just called a broken shoulder. Indeed. 00:00:22.500 --> 00:00:25.079 And it's an injury that really highlights how 00:00:25.079 --> 00:00:27.859 something seemingly straightforward, like a simple 00:00:27.859 --> 00:00:30.859 fall, can actually lead to surprisingly complex 00:00:30.859 --> 00:00:33.399 challenges. Right. So for this Deep Dive, we've 00:00:33.399 --> 00:00:36.039 looked at a range of expert sources, insights 00:00:36.039 --> 00:00:38.380 from the Orthopedic Trauma Association, detailed 00:00:38.380 --> 00:00:40.659 clinical reviews like stat pearls and ortho bullets, 00:00:41.140 --> 00:00:43.380 bits from the bone school, and also a summary 00:00:43.380 --> 00:00:46.460 document from the Stanford AVA lab. OK. And our 00:00:46.460 --> 00:00:48.520 mission today is really to distill the essential 00:00:48.520 --> 00:00:50.759 knowledge from all of that material. Why focus 00:00:50.759 --> 00:00:53.460 on this specific injury? Well, partly because 00:00:53.460 --> 00:00:55.560 it's remarkably common, isn't it, particularly 00:00:55.560 --> 00:00:59.149 among older adults? Yes, very much so. And managing 00:00:59.149 --> 00:01:02.390 it really seems to involve navigating complexity, 00:01:03.030 --> 00:01:05.569 evaluating trade -offs, often under uncertainty, 00:01:06.109 --> 00:01:08.989 and committing to what sounds like quite a demanding 00:01:08.989 --> 00:01:11.890 recovery. These feel like universal themes. Absolutely. 00:01:12.230 --> 00:01:15.590 By looking closely at the sort of anatomy of 00:01:15.590 --> 00:01:18.329 the problem, how we classify its severity, the 00:01:18.329 --> 00:01:21.209 nuanced choices around treatment, and the realities 00:01:21.209 --> 00:01:23.810 of recovery and managing potential risks in a 00:01:23.810 --> 00:01:27.219 specialist field like orthopedics, we definitely 00:01:27.219 --> 00:01:30.159 find parallels. Parallels to strategic challenges 00:01:30.159 --> 00:01:32.500 you might face in, well, any professional field 00:01:32.500 --> 00:01:35.439 really. It's about understanding a specific intricate 00:01:35.439 --> 00:01:38.500 system to gain perhaps broader insights into 00:01:38.500 --> 00:01:40.939 problem solving and resilience. Right, okay. 00:01:41.180 --> 00:01:42.879 Let's get into the mechanics of it then. When 00:01:42.879 --> 00:01:45.379 we talk about a proximal humerus fracture, where 00:01:45.379 --> 00:01:47.700 exactly are we focusing? What's the actual system 00:01:47.700 --> 00:01:49.379 we need to understand here? Okay, let's start 00:01:49.379 --> 00:01:51.239 with the basic structure, drawing on the descriptions 00:01:51.239 --> 00:01:53.939 and sources like the OTA and stat pearls. Your 00:01:53.939 --> 00:01:56.370 shoulder joint is... Well, it's a marvel of mobility, 00:01:56.430 --> 00:01:58.989 really. Yeah. And at its core, you have three 00:01:58.989 --> 00:02:03.390 bones. The clavicle, your collarbone, the scapula, 00:02:03.430 --> 00:02:05.549 which is the shoulder blade, and the humerus, 00:02:05.670 --> 00:02:08.069 your upper arm bone. OK. The proximal humerus 00:02:08.069 --> 00:02:10.610 is simply the section of that humerus closest 00:02:10.610 --> 00:02:13.229 to the shoulder joint. So essentially, the very 00:02:13.229 --> 00:02:15.629 top of the arm bone. So the part that forms the 00:02:15.629 --> 00:02:17.770 ball in the ball and socket joint of the shoulder. 00:02:18.189 --> 00:02:20.770 Precisely. But this ball region, it's not just 00:02:20.770 --> 00:02:23.789 one simple solid structure. To really understand 00:02:23.789 --> 00:02:26.289 how it breaks, orthopedically, it's often viewed 00:02:26.289 --> 00:02:28.610 as being made up of four functional parts. Four 00:02:28.610 --> 00:02:32.500 parts? Yes. This way of thinking was really crystallized 00:02:32.500 --> 00:02:35.620 by the surgeon Charles Near, whose classification 00:02:35.620 --> 00:02:37.840 system we'll definitely come back to. These parts 00:02:37.840 --> 00:02:40.319 are based on how the bone tends to fragment when 00:02:40.319 --> 00:02:42.960 it's injured, often along weaker lines or areas 00:02:42.960 --> 00:02:45.860 where key tendons attach. Four parts within just 00:02:45.860 --> 00:02:47.939 the top of that one bone. That already sounds 00:02:47.939 --> 00:02:50.620 more complex than just a simple break. What are 00:02:50.620 --> 00:02:53.219 they? Well, based on the detailed descriptions 00:02:53.219 --> 00:02:55.840 across our sources, stat pearls, ortho bullets, 00:02:55.939 --> 00:02:59.879 they all cover this. These four key parts are... 00:03:00.479 --> 00:03:03.639 Firstly, the articular segment. That's the rounded 00:03:03.639 --> 00:03:07.259 smooth cartilage covered surface of the humeral 00:03:07.259 --> 00:03:09.719 head itself. Right. The actual ball part that 00:03:09.719 --> 00:03:11.379 moves against the socket on the shoulder blade. 00:03:11.439 --> 00:03:13.879 The surface that allows that smooth movement. 00:03:14.099 --> 00:03:17.300 Exactly. Then... Just below that articular surface, 00:03:17.460 --> 00:03:19.520 you have the anatomic neck. Anatomic neck, okay. 00:03:19.620 --> 00:03:21.379 This is basically the line where the original 00:03:21.379 --> 00:03:23.500 growth plate was in childhood, separating the 00:03:23.500 --> 00:03:25.819 head from the rest of the bone. Fractures right 00:03:25.819 --> 00:03:27.460 along this line can be tricky because they're 00:03:27.460 --> 00:03:29.979 very close to the blood supply feeding the humeral 00:03:29.979 --> 00:03:32.400 head itself. Right, that sounds important. Okay, 00:03:32.539 --> 00:03:34.580 anatomic neck. What's the third part? The third 00:03:34.580 --> 00:03:37.139 is the surgical neck. This is located a bit further 00:03:37.139 --> 00:03:39.620 down the bone, below those bony bones called 00:03:39.620 --> 00:03:42.300 the tuberosities. We'll get to those next. Okay. 00:03:42.560 --> 00:03:44.919 It's often described as the narrowest point or 00:03:44.919 --> 00:03:47.000 perhaps the weakest structural zone of the upper 00:03:47.000 --> 00:03:49.800 humerus. And this is a critically important area 00:03:49.800 --> 00:03:52.580 because a very high percentage of proximal humerus 00:03:52.580 --> 00:03:54.960 fractures happen right here through the surgical 00:03:54.960 --> 00:03:58.000 neck, especially in things like falls onto an 00:03:58.000 --> 00:04:00.439 outstretched arm. It's just a frequent point 00:04:00.439 --> 00:04:02.699 of failure under stress. That makes sense, a 00:04:02.699 --> 00:04:05.300 point of sort of mechanical vulnerability. Okay, 00:04:05.300 --> 00:04:07.639 so we have the articular surface, the anatomic 00:04:07.639 --> 00:04:10.219 neck, the surgical neck. What's the fourth part? 00:04:10.379 --> 00:04:12.419 The fourth part, well, it actually refers to 00:04:12.419 --> 00:04:16.519 two bony prominences or bumps located just below 00:04:16.519 --> 00:04:18.560 the humeral head on the side of the bone. These 00:04:18.560 --> 00:04:21.240 are the greater tuberosity and the lesser tuberosity. 00:04:21.259 --> 00:04:23.300 Right. The greater tuberosity is on the outer 00:04:23.300 --> 00:04:25.899 side of the shoulder, and it's the crucial attachment 00:04:25.899 --> 00:04:28.199 point for three of the four rotator cuff muscles, 00:04:28.899 --> 00:04:31.600 the supraspinatus, infraspinatus, and teres minor. 00:04:31.709 --> 00:04:35.209 These muscles are absolutely vital for lifting 00:04:35.209 --> 00:04:38.709 and rotating the arm outwards. The lesser tuberosity 00:04:38.709 --> 00:04:40.569 is on the front of the bone, and that's where 00:04:40.569 --> 00:04:43.269 the subscapularis muscle attaches, which helps 00:04:43.269 --> 00:04:45.910 with inward rotation. So these tuberosities aren't 00:04:45.910 --> 00:04:48.269 just bumps then, they're actually anchors for 00:04:48.269 --> 00:04:50.129 the muscles that power our shoulder movement. 00:04:50.569 --> 00:04:53.329 Precisely. They are completely integral to the 00:04:53.329 --> 00:04:55.629 function and the stability of the joint. And 00:04:55.629 --> 00:04:58.629 actually, The groove that runs between these 00:04:58.629 --> 00:05:00.329 two tuberosities, that's called the occipital 00:05:00.329 --> 00:05:02.170 groove. That's where the long head of the biceps 00:05:02.170 --> 00:05:05.189 tendon runs. Okay. So when we talk about a proximal 00:05:05.189 --> 00:05:06.810 humerus fracture, we're talking about a break 00:05:06.810 --> 00:05:10.470 that affects one or more of these four functional 00:05:10.470 --> 00:05:13.550 units. The head, the anatomic neck, the surgical 00:05:13.550 --> 00:05:16.769 neck, or those tuberosities. And the nature of 00:05:16.769 --> 00:05:19.300 the fracture, it depends on... which of these 00:05:19.300 --> 00:05:22.639 parts break and, crucially, how they move relative 00:05:22.639 --> 00:05:24.819 to each other. Absolutely. That's the crux of 00:05:24.819 --> 00:05:27.620 it. The OTA source really highlights that the 00:05:27.620 --> 00:05:29.639 pattern and the severity are highly variable. 00:05:29.769 --> 00:05:32.310 It depends heavily on which parts are fractured 00:05:32.310 --> 00:05:34.589 and, really importantly, the extent to which 00:05:34.589 --> 00:05:37.350 these fractured segments have moved or, as we 00:05:37.350 --> 00:05:40.649 say, displaced from their normal anatomical position. 00:05:41.069 --> 00:05:43.589 Right. This displacement is absolutely key to 00:05:43.589 --> 00:05:46.009 determining the stability of the fracture and, 00:05:46.009 --> 00:05:48.329 ultimately, how it should be treated. That leads 00:05:48.329 --> 00:05:50.410 us neatly into how these injuries actually happen. 00:05:50.509 --> 00:05:52.230 You mentioned it's not just one type of event. 00:05:52.610 --> 00:05:54.490 The sources point to quite a distinct pattern, 00:05:54.589 --> 00:05:57.110 don't they? They do, yes. Staff pearls and ortho 00:05:57.110 --> 00:05:59.709 bullets. Both really emphasize what's called 00:05:59.709 --> 00:06:02.569 the classical bimodal distribution of these fractures. 00:06:02.790 --> 00:06:05.529 Bimodal, meaning? It means the injury mechanism 00:06:05.529 --> 00:06:08.189 and the type of patient affected tend to fall 00:06:08.189 --> 00:06:12.050 into two pretty distinct peaks, or groups. Understanding 00:06:12.050 --> 00:06:14.370 these patterns helps us understand the underlying 00:06:14.370 --> 00:06:17.329 risk factors, and often the likely bone quality 00:06:17.329 --> 00:06:19.829 involved. OK, let's explore these two groups. 00:06:20.029 --> 00:06:22.750 What's the most common scenario then? Well, the 00:06:22.750 --> 00:06:25.120 largest group, and this accounts for the clear 00:06:25.120 --> 00:06:28.120 majority of these fractures, involves older adults, 00:06:28.920 --> 00:06:31.980 typically people over the age of 65. Okay. In 00:06:31.980 --> 00:06:34.160 this demographic, the injury is usually caused 00:06:34.160 --> 00:06:37.379 by a low energy mechanism. Most commonly, it's 00:06:37.379 --> 00:06:39.839 a simple fall from standing height. The classic 00:06:39.839 --> 00:06:42.639 scenario is someone tripping, falling onto an 00:06:42.639 --> 00:06:45.279 outstretched hand, or perhaps directly onto their 00:06:45.279 --> 00:06:47.449 elbow or shoulder. And this is where bone density 00:06:47.449 --> 00:06:49.810 comes into play, I assume. Exactly. Stat Pearls 00:06:49.810 --> 00:06:52.189 explicitly notes that in this older population, 00:06:52.709 --> 00:06:55.129 these fractures are very frequently fragility 00:06:55.129 --> 00:06:57.550 fracture. Fragility fractures, meaning the bone 00:06:57.550 --> 00:07:01.009 breaks easily. Precisely. It means the bone has 00:07:01.009 --> 00:07:03.569 broken, not necessarily because the force was 00:07:03.569 --> 00:07:06.069 immense, but because the bone quality itself 00:07:06.069 --> 00:07:08.790 has been compromised, usually by osteoporosis 00:07:08.790 --> 00:07:11.329 or osteopenia thinning of the bone. The bone 00:07:11.329 --> 00:07:13.230 simply isn't strong enough to withstand even 00:07:13.230 --> 00:07:16.290 a moderate force. And these fragility fractures 00:07:16.290 --> 00:07:18.810 are a really significant contributor to the overall 00:07:18.810 --> 00:07:21.149 healthcare burden associated with osteoporosis. 00:07:22.050 --> 00:07:24.629 The incidence of proximal humerus fractures is 00:07:24.629 --> 00:07:28.050 cited as high as maybe 4 % to 6 % of all adult 00:07:28.050 --> 00:07:31.069 fractures. And notably, there's a strong female 00:07:31.069 --> 00:07:34.110 predominance, a reported 2 .1 female to male 00:07:34.110 --> 00:07:36.990 ratio, which reflects the higher prevalence of 00:07:36.990 --> 00:07:39.810 osteoporosis in women. So a very common issue 00:07:39.810 --> 00:07:42.370 in older women, often acting as a sort of red 00:07:42.370 --> 00:07:45.029 flag for underlying bone weakness. What about 00:07:45.029 --> 00:07:46.810 the other group in this bimodal distribution? 00:07:46.990 --> 00:07:49.350 The second peak involves younger, typically more 00:07:49.350 --> 00:07:51.670 active patients. Now for them, it takes a much 00:07:51.670 --> 00:07:53.810 higher energy trauma to cause a fracture in the 00:07:53.810 --> 00:07:55.829 proximal humerus because their bone is generally 00:07:55.829 --> 00:07:58.769 much stronger and denser. Examples of these high 00:07:58.769 --> 00:08:02.089 energy mechanisms would be things like road traffic 00:08:02.089 --> 00:08:05.069 collisions, falls from significant height, or 00:08:05.069 --> 00:08:07.850 maybe high impact sports injuries. That's described 00:08:07.850 --> 00:08:10.699 in the OTA and STAPROL sources. Right. These 00:08:10.699 --> 00:08:13.540 injuries in younger patients are often more severe. 00:08:13.920 --> 00:08:16.319 They might involve more comminution. That means 00:08:16.319 --> 00:08:18.620 shattering of the bone. And they carry a higher 00:08:18.620 --> 00:08:20.759 risk of associated injuries to the surrounding 00:08:20.759 --> 00:08:23.560 soft tissues, nerves, or blood vessels, just 00:08:23.560 --> 00:08:25.939 because of the sheer force involved. It's a stark 00:08:25.939 --> 00:08:28.620 contrast, isn't it? A simple stumble for one 00:08:28.620 --> 00:08:31.540 group versus a major impact for the other really 00:08:31.540 --> 00:08:33.679 highlights different underlying vulnerabilities 00:08:33.679 --> 00:08:37.919 or the external forces at play. So someone sustains 00:08:37.919 --> 00:08:40.809 this injury? What are the immediate signs and 00:08:40.809 --> 00:08:43.110 symptoms you'd expect to see? Well the clinical 00:08:43.110 --> 00:08:45.429 presentation is usually quite dramatic and pretty 00:08:45.429 --> 00:08:47.610 typical of a significant bone injury near a major 00:08:47.610 --> 00:08:50.769 joint. Severe pain is almost always the primary 00:08:50.769 --> 00:08:53.070 symptom localized right around the shoulder and 00:08:53.070 --> 00:08:55.570 the upper arm and this pain is significantly 00:08:55.570 --> 00:08:57.789 worse with any attempt at all to move the arm. 00:08:58.389 --> 00:09:00.450 Swelling and bruising are also very common and 00:09:00.450 --> 00:09:02.950 because of gravity The bruising can actually 00:09:02.950 --> 00:09:05.149 be quite extensive. It might track downwards 00:09:05.149 --> 00:09:07.450 over several days, sometimes appearing around 00:09:07.450 --> 00:09:09.950 the elbow, or even further down in the forearm 00:09:09.950 --> 00:09:12.789 or hand. That's mentioned in the OTA and unknown 00:09:12.789 --> 00:09:15.889 19 sources. Patients will typically hold the 00:09:15.889 --> 00:09:18.509 injured arm very close to their body, often supporting 00:09:18.509 --> 00:09:21.509 it with the other hand, and report an inability 00:09:21.509 --> 00:09:24.370 or just extreme reluctance to move it actively. 00:09:24.570 --> 00:09:27.389 Sometimes they might describe a grating or grinding 00:09:27.389 --> 00:09:30.129 sensation we call that crepitus if the fractured 00:09:30.129 --> 00:09:32.429 bone ends are unstable and rubbing together. 00:09:32.889 --> 00:09:35.210 And beyond just observing and asking about the 00:09:35.210 --> 00:09:37.750 pain, a physical examination sounds absolutely 00:09:37.750 --> 00:09:39.929 crucial to assess the full extent of the damage. 00:09:40.309 --> 00:09:42.549 Oh, absolutely critical. A thorough physical 00:09:42.549 --> 00:09:45.769 examination is indispensable. The clinician will 00:09:45.769 --> 00:09:47.950 visually inspect the shoulder looking for any 00:09:47.950 --> 00:09:49.730 obvious deformity, swelling, or that breathing 00:09:49.730 --> 00:09:52.309 we mentioned. They'll gently palpate the area, 00:09:52.490 --> 00:09:55.049 feel around to identify points of maximal tenderness, 00:09:55.190 --> 00:09:57.929 and potentially feel for that crepitus. However, 00:09:58.149 --> 00:10:00.129 a vital component of the examination, and this 00:10:00.129 --> 00:10:02.049 is heavily emphasized in stepperals and ortho 00:10:02.049 --> 00:10:05.529 -bullets, is the neurovascular assessment. Neurovascular, 00:10:06.250 --> 00:10:09.429 checking nerves and blood vessels. Exactly. checking 00:10:09.429 --> 00:10:11.149 the function of the nerves and the blood vessels 00:10:11.149 --> 00:10:14.110 supplying the arm and hand. Why is that specific 00:10:14.110 --> 00:10:17.649 check so important in a shoulder fracture compared 00:10:17.649 --> 00:10:21.029 to, say, a broken wrist? It's because of the 00:10:21.029 --> 00:10:24.210 very close proximity of major nerves and blood 00:10:24.210 --> 00:10:27.360 vessels to the proximal humerus. particularly 00:10:27.360 --> 00:10:29.379 around that surgical neck area where so many 00:10:29.379 --> 00:10:32.759 fractures occur. The nerve most frequently at 00:10:32.759 --> 00:10:34.919 risk in these injuries is the axillary nerve. 00:10:35.279 --> 00:10:37.019 This nerve actually wraps around the surgical 00:10:37.019 --> 00:10:39.679 neck of the humerus, and it supplies motor function 00:10:39.679 --> 00:10:42.100 to the deltoid muscle, that's the big muscle 00:10:42.100 --> 00:10:44.120 covering the shoulder, essential for lifting 00:10:44.120 --> 00:10:46.750 the arm away from the body. It also supplies 00:10:46.750 --> 00:10:49.429 sensation to the skin over the outer aspect of 00:10:49.429 --> 00:10:51.590 the shoulder, sometimes called the regimental 00:10:51.590 --> 00:10:54.690 badge area. So damage to that nerve could mean 00:10:54.690 --> 00:10:57.190 real weakness in lifting the arm. Precisely. 00:10:57.590 --> 00:11:00.289 A complete axillary nerve injury can result in 00:11:00.289 --> 00:11:03.590 a noticeable weakness or even inability to abduct 00:11:03.590 --> 00:11:06.110 to lift the arm sideways and often a patch of 00:11:06.110 --> 00:11:08.429 numbness on that outer shoulder. Ortho Bullets 00:11:08.429 --> 00:11:11.950 notes that axillary nerve palsy or weakness can 00:11:11.950 --> 00:11:14.809 occur in quite a significant percentage of cases, 00:11:15.110 --> 00:11:18.379 potentially up to 58%. based on some EMG studies, 00:11:18.639 --> 00:11:20.419 although many of these might be temporary or 00:11:20.419 --> 00:11:23.500 partial injuries, what we call neuropraxia. It's 00:11:23.500 --> 00:11:25.320 also highlighted that the nerve is particularly 00:11:25.320 --> 00:11:27.379 vulnerable during certain surgical approaches. 00:11:27.860 --> 00:11:30.139 For instance, with lateral pin placement, if 00:11:30.139 --> 00:11:32.519 doing pericucaneous fixation. Are blood vessels 00:11:32.519 --> 00:11:35.460 also at risk then? Yes, though perhaps less commonly 00:11:35.460 --> 00:11:37.860 injured than the axillary nerve, especially in 00:11:37.860 --> 00:11:40.820 lower energy fractures. The axillary artery runs 00:11:40.820 --> 00:11:44.129 close by and can potentially be damaged. particularly 00:11:44.129 --> 00:11:47.730 in severely displaced fractures or fracture dislocations 00:11:47.730 --> 00:11:50.909 or in those high -energy traumas. Scott Pearls 00:11:50.909 --> 00:11:53.529 mentions arterial injury occurs in... perhaps 00:11:53.529 --> 00:11:56.549 up to 5 % of cases. So it's absolutely crucial 00:11:56.549 --> 00:11:58.710 to check the patient's pulses in the wrist and 00:11:58.710 --> 00:12:01.350 hand and assess the color and temperature of 00:12:01.350 --> 00:12:03.129 the limb to make sure there's adequate blood 00:12:03.129 --> 00:12:05.570 flow. Although, as OrthoBullets points out, the 00:12:05.570 --> 00:12:08.309 shoulder has quite good collateral circulation 00:12:08.309 --> 00:12:11.350 alternative blood pathways. So relying solely 00:12:11.350 --> 00:12:14.289 on pulses might sometimes miss a more subtle 00:12:14.289 --> 00:12:17.500 vascular issue. Assessing motor function and 00:12:17.500 --> 00:12:20.379 sensation for other major nerves like the radial 00:12:20.379 --> 00:12:23.179 and musculocutaneous nerves is also part of a 00:12:23.179 --> 00:12:26.519 thorough exam. So pain, bruising, swelling, potential 00:12:26.519 --> 00:12:29.259 nerve, or even vascular compromise sounds quite 00:12:29.259 --> 00:12:31.740 involved. How do clinicians then get a really 00:12:31.740 --> 00:12:34.919 precise blueprint of the fracture pattern itself 00:12:34.919 --> 00:12:36.799 to guide their decisions? Yeah, that's where 00:12:36.799 --> 00:12:38.940 medical imaging becomes absolutely indispensable. 00:12:39.599 --> 00:12:41.559 Radiographs or x -rays, as most people know them, 00:12:41.899 --> 00:12:44.279 are the absolute cornerstone. They're the mandatory 00:12:44.279 --> 00:12:46.820 initial step. Right. And our sources are very 00:12:46.820 --> 00:12:48.919 specific about the views required to get a complete 00:12:48.919 --> 00:12:51.100 picture. You need what's called a complete trauma 00:12:51.100 --> 00:12:52.659 series of the shoulder. This isn't just one or 00:12:52.659 --> 00:12:54.840 two quick pictures. A trauma series? What does 00:12:54.840 --> 00:12:57.019 that typically include? Well, it involves several 00:12:57.019 --> 00:12:59.639 views taken at different angles. The aim is to 00:12:59.639 --> 00:13:02.600 get orthogonal, meaning 90 -degree perspectives, 00:13:03.000 --> 00:13:04.879 which are essential for judging displacement 00:13:04.879 --> 00:13:07.259 in multiple planes. You need to see it front 00:13:07.259 --> 00:13:10.240 -on and side -on, essentially. OK. Q views usually 00:13:10.240 --> 00:13:14.980 include, first, a true AP anteroposterior view, 00:13:15.379 --> 00:13:18.299 sometimes called a grassy view. This is taken 00:13:18.299 --> 00:13:20.559 with the patient rotated slightly so the x -ray 00:13:20.559 --> 00:13:22.659 beam goes straight through the glenohumeral joint 00:13:22.659 --> 00:13:25.620 space, showing it clearly without the scapula 00:13:25.620 --> 00:13:27.639 overlapping. Gives you that front -on view of 00:13:27.639 --> 00:13:30.200 the joint. Right. Second, a scapular Y view. 00:13:30.519 --> 00:13:33.580 This is a lateral or side -on view. It's taken 00:13:33.580 --> 00:13:35.519 with the patient positioned so the scapula is 00:13:35.519 --> 00:13:37.480 seen on its side, and it looks a bit like the 00:13:37.480 --> 00:13:40.100 letter Y. The humerus should normally sit right 00:13:40.100 --> 00:13:42.779 in the center of that Y. This view is excellent 00:13:42.779 --> 00:13:44.620 for assessing if the humeral head has shifted 00:13:44.620 --> 00:13:46.879 forwards or backwards relative to the socket, 00:13:46.899 --> 00:13:50.080 and it also helps rule out shoulder dislocations. 00:13:50.220 --> 00:13:52.840 And a third view. Yes, usually an axillary lateral 00:13:52.840 --> 00:13:55.580 view. This one is taken ideally with the arm 00:13:55.580 --> 00:13:57.600 abducted, lifted slightly away from the body. 00:13:57.919 --> 00:13:59.840 If the patient can manage it, shooting the x 00:13:59.840 --> 00:14:03.019 -ray beam up from the armpit area. This view 00:14:03.019 --> 00:14:05.899 is crucial for assessing displacement in the 00:14:05.899 --> 00:14:09.179 axial plane. again, forward or backward movement, 00:14:09.700 --> 00:14:11.919 and for seeing those tuberosities clearly in 00:14:11.919 --> 00:14:14.639 profile. Now, if the patient can't lift their 00:14:14.639 --> 00:14:17.659 arm due to pain or the injury itself, modified 00:14:17.659 --> 00:14:19.779 axial views or other techniques might be needed. 00:14:20.000 --> 00:14:21.720 That makes sense, getting multiple angles to 00:14:21.720 --> 00:14:23.179 see the problem from all sides, like looking 00:14:23.179 --> 00:14:25.000 at a complex structure from different viewpoints 00:14:25.000 --> 00:14:27.659 before you decide how to fix it. What if those 00:14:27.659 --> 00:14:30.659 standard x -rays aren't quite enough, if it looks 00:14:30.659 --> 00:14:33.750 particularly complicated? Exactly. If the fracture 00:14:33.750 --> 00:14:36.549 pattern is very complex, maybe shattered into 00:14:36.549 --> 00:14:39.110 many pieces, or if there's a strong suspicion 00:14:39.110 --> 00:14:41.509 that the break extends right into the joint surface 00:14:41.509 --> 00:14:43.590 itself, what we call intra -articular involvement, 00:14:43.929 --> 00:14:46.250 or simply if you need more detail for surgical 00:14:46.250 --> 00:14:49.750 planning, then a CT scan, computed tomography, 00:14:50.070 --> 00:14:53.169 is incredibly valuable. Stat pearls and orthobolates 00:14:53.169 --> 00:14:56.450 both highlight its utility. A CT scan provides 00:14:56.450 --> 00:14:59.149 detailed cross -sectional images, almost like 00:14:59.149 --> 00:15:02.080 slices through the bone. It allows surgeons to 00:15:02.080 --> 00:15:04.320 see precisely the number and position of all 00:15:04.320 --> 00:15:06.679 the fragments, the degree of convolution, how 00:15:06.679 --> 00:15:09.460 shattered it is, and the exact relationship of 00:15:09.460 --> 00:15:12.500 the humeral head to the glenoid socket. This 00:15:12.500 --> 00:15:14.559 is vital for planning how to fix it, whether 00:15:14.559 --> 00:15:17.639 with pins, plates, or even a replacement. It's 00:15:17.639 --> 00:15:19.360 particularly good for assessing the position 00:15:19.360 --> 00:15:21.700 of those two porosities and the state of the 00:15:21.700 --> 00:15:24.980 articular surface. And MRI, is that ever necessary 00:15:24.980 --> 00:15:28.840 for these fracture? MRI, magnetic resonance imaging. 00:15:29.100 --> 00:15:31.539 is less commonly used for assessing the bone 00:15:31.539 --> 00:15:34.259 fracture itself. Its strength is really in evaluating 00:15:34.259 --> 00:15:37.200 soft tissues. As the Orthobolus points out, an 00:15:37.200 --> 00:15:39.220 MRI might be considered if there's a strong suspicion 00:15:39.220 --> 00:15:41.759 of a significant associated soft tissue injury 00:15:41.759 --> 00:15:43.820 that could really impact the treatment or the 00:15:43.820 --> 00:15:46.779 outcome. For example, a complete tear of the 00:15:46.779 --> 00:15:49.080 rotator cuff tendons, or perhaps significant 00:15:49.080 --> 00:15:51.259 ligament damage, which might happen alongside 00:15:51.259 --> 00:15:53.220 the fracture in those higher energy traumas. 00:15:53.370 --> 00:15:56.190 Okay, so imaging gives us that detailed blueprint. 00:15:56.750 --> 00:15:59.409 Then comes the task of actually classifying the 00:15:59.409 --> 00:16:02.330 damage, which seems to be where orthopedic surgeons 00:16:02.330 --> 00:16:05.169 translate all this complex image data into a 00:16:05.169 --> 00:16:07.509 framework for making decisions. We mentioned 00:16:07.509 --> 00:16:10.649 the near classification earlier. Let's dig into 00:16:10.649 --> 00:16:13.519 that. How does it work, and why is this act of 00:16:13.519 --> 00:16:16.299 classification so central to deciding the path 00:16:16.299 --> 00:16:18.940 forward? Yeah, classification is absolutely fundamental 00:16:18.940 --> 00:16:21.259 in orthopedic trauma. It does two main things. 00:16:21.639 --> 00:16:23.940 It provides a common language so surgeons can 00:16:23.940 --> 00:16:25.879 communicate effectively about specific injury 00:16:25.879 --> 00:16:28.840 patterns, and it provides a framework for grouping 00:16:28.840 --> 00:16:31.840 similar injuries together, which in turn helps 00:16:31.840 --> 00:16:34.340 guide treatment algorithms and allows us to compare 00:16:34.340 --> 00:16:37.320 outcomes in research studies. The near classification, 00:16:37.659 --> 00:16:39.259 which is based on those four functional parts 00:16:39.259 --> 00:16:41.539 we discussed earlier, the articular surface or 00:16:41.539 --> 00:16:44.360 head, the greater tuberosity, the lesser tuberosity, 00:16:44.659 --> 00:16:47.440 and the shaft or surgical neck region is arguably 00:16:47.440 --> 00:16:49.879 the most widely used system for proximal humerus 00:16:49.879 --> 00:16:52.440 fractures. And it classifies fractures based 00:16:52.440 --> 00:16:54.480 purely on the number of these four primary parts 00:16:54.480 --> 00:16:57.480 that are significantly displaced. So it's not 00:16:57.480 --> 00:16:59.559 just about how many fracture lines you can see 00:16:59.559 --> 00:17:02.200 on the x -ray, but specifically about how far 00:17:02.200 --> 00:17:04.519 the main pieces have moved. That feels like a 00:17:04.519 --> 00:17:06.880 key distinction. It is the key distinction. That's 00:17:06.880 --> 00:17:10.069 the critical insight from near system. A fracture 00:17:10.069 --> 00:17:13.329 line can exist, maybe multiple lines, but if 00:17:13.329 --> 00:17:15.509 the pieces remain in relatively good alignment, 00:17:16.150 --> 00:17:18.170 it's treated very differently than if they've 00:17:18.170 --> 00:17:20.569 shifted significantly out of place. According 00:17:20.569 --> 00:17:23.589 to StatPearls and OrthoBullets, a segment is 00:17:23.589 --> 00:17:26.289 considered significantly displaced if it is moved 00:17:26.289 --> 00:17:28.890 by more than one centimeter. or 10 millimeters, 00:17:29.170 --> 00:17:32.109 or if it's angled by more than 45 degrees relative 00:17:32.109 --> 00:17:34.690 to its normal anatomical position. Right. Those 00:17:34.690 --> 00:17:37.250 are the specific thresholds used to determine 00:17:37.250 --> 00:17:39.529 if a part counts towards the classification number. 00:17:39.710 --> 00:17:41.450 Got it. Okay, so let's walk through the near 00:17:41.450 --> 00:17:43.710 categories based on that displacement rule. How 00:17:43.710 --> 00:17:46.750 does it start? Right. It starts simply. A one 00:17:46.750 --> 00:17:49.089 -part fracture. This means there are fracture 00:17:49.089 --> 00:17:51.650 lines present in the proximal humerus, potentially 00:17:51.650 --> 00:17:54.329 separating multiple segments, but, and this is 00:17:54.329 --> 00:17:56.890 the crucial bit, none of the four main parts, 00:17:57.109 --> 00:18:00.089 head, tuberosity, shaft, are displaced by more 00:18:00.089 --> 00:18:02.890 than that one centimeter or 45 degrees. So it's 00:18:02.890 --> 00:18:06.009 key, multiple cracks don't automatically make 00:18:06.009 --> 00:18:08.309 it a multi -part fracture in the Nair system 00:18:08.309 --> 00:18:10.710 if the fragments are still essentially in place. 00:18:11.349 --> 00:18:13.309 Orthobolus notes that these minimally displaced 00:18:13.309 --> 00:18:15.829 fractures often technically two -part surgical 00:18:15.829 --> 00:18:18.309 neck fractures, but with minimal shift, are actually 00:18:18.309 --> 00:18:21.170 the most common type we see. So even if there 00:18:21.170 --> 00:18:23.970 are breaks technically separating several areas, 00:18:24.450 --> 00:18:27.109 if everything stays relatively put, it's classified 00:18:27.109 --> 00:18:29.720 as a one -part. That's maybe a bit counterintuitive 00:18:29.720 --> 00:18:32.519 at first. What's a two -part fracture then? A 00:18:32.519 --> 00:18:34.599 two -part fracture means there are fracture lines 00:18:34.599 --> 00:18:37.339 separating two or more segments, but only one 00:18:37.339 --> 00:18:40.279 of those four major functional parts is significantly 00:18:40.279 --> 00:18:42.559 displaced again, more than one centimeter or 00:18:42.559 --> 00:18:45.400 45 degrees. Just one part moved significantly. 00:18:45.559 --> 00:18:48.539 Yes. A very common example highlighted by ortho 00:18:48.539 --> 00:18:51.180 bullets is a surgical neck fracture, where the 00:18:51.180 --> 00:18:53.500 main shaft fragment is displaced upwards or angled. 00:18:53.710 --> 00:18:56.450 but the humeral head and the tuberosities remain 00:18:56.450 --> 00:18:59.309 together as a single unit and in reasonable alignment 00:18:59.309 --> 00:19:02.990 relative to each other. Or, alternatively, maybe 00:19:02.990 --> 00:19:05.170 the greater tuberosity alone is pulled off and 00:19:05.170 --> 00:19:07.309 displaced, but the head and shaft remain aligned. 00:19:07.390 --> 00:19:09.210 Okay, makes sense. And it just increases from 00:19:09.210 --> 00:19:12.529 there. Exactly. A three -part fracture involves 00:19:12.529 --> 00:19:15.210 fracture lines separating three or more segments, 00:19:15.630 --> 00:19:18.309 and now two of the four primary parts are significantly 00:19:18.309 --> 00:19:21.150 displaced relative to the others. Two parts out 00:19:21.150 --> 00:19:24.190 of place. Yes. So a typical three -part fracture 00:19:24.190 --> 00:19:26.289 might involve a fracture through the surgical 00:19:26.289 --> 00:19:29.470 neck with significant displacement of both the 00:19:29.470 --> 00:19:32.049 greater and lesser tuberosities relative to the 00:19:32.049 --> 00:19:34.960 humeral head and shaft. or perhaps displacement 00:19:34.960 --> 00:19:37.299 of just one tuberosity in the surgical neck fragment. 00:19:37.799 --> 00:19:40.799 The point is, two of those four core units are 00:19:40.799 --> 00:19:43.319 significantly out of alignment. Right. And finally, 00:19:43.400 --> 00:19:45.799 the most severe in this system. That would be 00:19:45.799 --> 00:19:48.059 the four -part fracture. This is the most complex 00:19:48.059 --> 00:19:50.220 and generally unstable pattern classified by 00:19:50.220 --> 00:19:52.500 NEAR. It means there are fracture lines separating 00:19:52.500 --> 00:19:55.079 all four primary parts, the articular segment 00:19:55.079 --> 00:19:57.880 head, the greater tuberosity, the lesser tuberosity, 00:19:57.920 --> 00:20:00.329 and the shaft. And three of these four parts 00:20:00.329 --> 00:20:02.650 are significantly displaced relative to each 00:20:02.650 --> 00:20:05.430 other and the remaining segment. The blood supply 00:20:05.430 --> 00:20:08.029 to the humeral head is often significantly compromised 00:20:08.029 --> 00:20:10.329 in these injuries, which dramatically increases 00:20:10.329 --> 00:20:12.430 the risk of the bone in the head dying off what 00:20:12.430 --> 00:20:16.609 we call a vascular necrosis, or AVN. Okay. OrthoBullets 00:20:16.609 --> 00:20:18.750 also mentions some specific patterns that are 00:20:18.750 --> 00:20:21.589 particularly problematic, like fractures right 00:20:21.589 --> 00:20:23.690 through the anatomic neck, which have a very 00:20:23.690 --> 00:20:27.069 high risk of AVN, fracture dislocations, where 00:20:27.069 --> 00:20:29.109 the humeral head is not only broken but also 00:20:29.109 --> 00:20:31.369 completely out of the socket, and head split 00:20:31.369 --> 00:20:33.890 fractures, where the articular surface itself 00:20:33.890 --> 00:20:36.750 is actually shattered. These are often considered 00:20:36.750 --> 00:20:39.750 within or alongside the four -part category due 00:20:39.750 --> 00:20:41.849 to their severity and implications for treatment, 00:20:42.390 --> 00:20:44.599 especially the risk to blood supply. So the NEAR 00:20:44.599 --> 00:20:47.839 system provides a kind of shorthand, driven entirely 00:20:47.839 --> 00:20:50.539 by displacement, for communicating the complexity 00:20:50.539 --> 00:20:53.619 and the likely instability of the fracture. We 00:20:53.619 --> 00:20:56.559 also saw mention of another system, the AOTA 00:20:56.559 --> 00:20:59.500 classification. Is that widely used as well, 00:20:59.500 --> 00:21:01.740 or is it more for specific purposes? Yes, the 00:21:01.740 --> 00:21:04.039 AOATA system is another important classification, 00:21:04.099 --> 00:21:06.559 and it's also referenced in StatPearls and OrthoBolix. 00:21:06.660 --> 00:21:09.180 It's generally a more detailed and comprehensive 00:21:09.180 --> 00:21:11.819 system than NEAR. It's actually part of a much 00:21:11.819 --> 00:21:14.809 larger universal system. designed for classifying 00:21:14.809 --> 00:21:18.509 all bone fractures throughout the body. It organizes 00:21:18.509 --> 00:21:21.369 proximal humerus fractures into three main groups 00:21:21.369 --> 00:21:24.769 labeled A, B, and C, based primarily on whether 00:21:24.769 --> 00:21:27.410 the fracture is extra -articular, meaning it 00:21:27.410 --> 00:21:29.619 doesn't involve the joint surface directly. Those 00:21:29.619 --> 00:21:32.579 are the A types. Partially intraarticular, some 00:21:32.579 --> 00:21:34.259 involvement of the joint surface, the B types. 00:21:34.599 --> 00:21:37.000 Or fully intraarticular, crossing the joint surface 00:21:37.000 --> 00:21:39.740 significantly, the C types. Right. And then within 00:21:39.740 --> 00:21:42.539 each of those groups, there are numerous subgroups 00:21:42.539 --> 00:21:45.039 that detail specific fracture patterns and the 00:21:45.039 --> 00:21:48.569 level of convolution or shattering. Unknown19 00:21:48.569 --> 00:21:51.549 mentions that a newer version from 2018 attempts 00:21:51.549 --> 00:21:54.049 to integrate some of NEAR's concepts about displacement 00:21:54.049 --> 00:21:56.670 while providing even greater descriptive power. 00:21:57.009 --> 00:21:59.970 So, more detailed. Yes, much more granular. It's 00:21:59.970 --> 00:22:01.730 often preferred in research settings because 00:22:01.730 --> 00:22:04.089 it allows for very precise comparisons between 00:22:04.089 --> 00:22:06.509 studies. And it's also very useful for detailed 00:22:06.509 --> 00:22:08.369 preoperative planning, especially for the really 00:22:08.369 --> 00:22:11.089 complex cases, as it allows for finer distinctions 00:22:11.089 --> 00:22:13.289 in the fracture patterns. But perhaps for day 00:22:13.289 --> 00:22:15.549 -to -day communication, NEAR is still very commonly 00:22:15.549 --> 00:22:18.279 used because of its relative simplicity based 00:22:18.279 --> 00:22:21.000 on that key concept of displacement. Okay, so 00:22:21.000 --> 00:22:23.759 we've sort of dissected the anatomy, understood 00:22:23.759 --> 00:22:26.079 the ways it breaks, and how those breaks are 00:22:26.079 --> 00:22:29.259 classified based on displacement. Now comes the 00:22:29.259 --> 00:22:32.200 really crucial, and it sounds like often challenging 00:22:32.200 --> 00:22:35.779 phase, deciding on the actual treatment. This 00:22:35.779 --> 00:22:38.759 seems less like a simple A or B choice and much 00:22:38.759 --> 00:22:41.539 more like navigating a complex decision tree, 00:22:41.759 --> 00:22:44.180 especially given all the variability and patience 00:22:44.180 --> 00:22:46.559 in fracture patterns. It is indeed a complex 00:22:46.559 --> 00:22:48.839 decision. This is where applying all that knowledge 00:22:48.839 --> 00:22:51.380 to a very specific situation becomes paramount, 00:22:51.500 --> 00:22:53.660 much like, as you say, strategic decision making 00:22:53.660 --> 00:22:56.480 in other fields. And here's where it gets really 00:22:56.480 --> 00:22:58.779 interesting and perhaps quite counterintuitive 00:22:58.779 --> 00:23:00.960 for many people. Okay. The sources we looked 00:23:00.960 --> 00:23:03.440 at consistently state that the majority of proximal 00:23:03.440 --> 00:23:05.640 humerus fractures are actually treated successfully 00:23:05.640 --> 00:23:08.079 without surgery. Really? That is surprising. 00:23:08.259 --> 00:23:10.119 When you picture a broken shoulder, I think most 00:23:10.119 --> 00:23:12.259 people instinctively assume surgery is needed. 00:23:12.380 --> 00:23:14.619 It's a common assumption, but the data suggests 00:23:14.619 --> 00:23:17.640 otherwise. Both the OTA and StatPearl site figures 00:23:17.640 --> 00:23:20.319 suggesting that somewhere between 80 % and 85 00:23:20.319 --> 00:23:23.039 % of these fractures can be managed non -operatively. 00:23:23.230 --> 00:23:26.849 80 to 85 percent. Wow! So non -operative management 00:23:26.849 --> 00:23:29.470 is the default path for most. For fractures that 00:23:29.470 --> 00:23:31.890 are minimally displaced, and remember what minimally 00:23:31.890 --> 00:23:35.049 displaced means in the Nair system, no part displaced 00:23:35.049 --> 00:23:38.309 more than one centimeter or 45 degrees non -operative 00:23:38.309 --> 00:23:40.930 management is generally the preferred approach. 00:23:40.970 --> 00:23:44.309 Okay. This includes almost all one -part fractures, 00:23:44.430 --> 00:23:46.670 even if there are multiple fracture lines visible, 00:23:46.970 --> 00:23:49.789 and indeed many two -part surgical neck fractures 00:23:49.789 --> 00:23:51.730 where the displacement is still within those 00:23:51.730 --> 00:23:54.730 accepted limits. Even some displaced greater 00:23:54.730 --> 00:23:57.329 tuberosity fractures might be managed non -operatively 00:23:57.329 --> 00:24:00.349 initially. Although ortho bullets specifies that 00:24:00.349 --> 00:24:02.329 displacement of the greater tuberosity by more 00:24:02.329 --> 00:24:04.730 than about five millimeters is usually considered 00:24:04.730 --> 00:24:07.210 unacceptable for non -operative treatment. Why 00:24:07.210 --> 00:24:10.190 is that specific tuberosity displacement such 00:24:10.190 --> 00:24:12.690 an issue? Because the rotator cuff muscles attach 00:24:12.690 --> 00:24:15.250 there. If that fragment heals in a position that's 00:24:15.250 --> 00:24:17.829 too high or too far back, it can physically block 00:24:17.829 --> 00:24:20.210 the shoulder from moving properly. causing painful 00:24:20.210 --> 00:24:22.450 impingement and significant loss of function, 00:24:22.609 --> 00:24:24.769 especially lifting the arm. The muscles pull 00:24:24.769 --> 00:24:27.269 it out of place. Right, makes sense. So if the 00:24:27.269 --> 00:24:29.430 pieces are still in relatively good alignment, 00:24:29.869 --> 00:24:32.289 the body is often capable of healing it itself 00:24:32.289 --> 00:24:35.650 given the chance. Precisely. The goal of non 00:24:35.650 --> 00:24:37.990 -operative treatment is simply to allow the bone 00:24:37.990 --> 00:24:40.529 to heal naturally. in an acceptable position 00:24:40.529 --> 00:24:42.869 while trying to maintain as much shoulder function 00:24:42.869 --> 00:24:45.670 as possible throughout the process. It's essentially 00:24:45.670 --> 00:24:49.269 a trust in the body's own biology. OK. This management 00:24:49.269 --> 00:24:51.890 typically starts with a period of immobilization, 00:24:51.970 --> 00:24:54.029 usually just for a few weeks, maybe two to three, 00:24:54.509 --> 00:24:57.150 in a sling or a similar support like a shoulder 00:24:57.150 --> 00:25:00.109 immobilizer. This is primarily for comfort during 00:25:00.109 --> 00:25:03.309 the initial very painful phase, and also to provide 00:25:03.309 --> 00:25:05.410 some protection for the healing tissues. Just 00:25:05.410 --> 00:25:08.369 a few weeks of immobilization, not months of 00:25:08.369 --> 00:25:11.369 being completely still then. Crucially, no. And 00:25:11.369 --> 00:25:13.410 this is a really key point highlighted across 00:25:13.410 --> 00:25:16.609 the sources. Prolonged, rigid immobilization 00:25:16.609 --> 00:25:18.869 of the shoulder is actually detrimental. Why 00:25:18.869 --> 00:25:21.650 is that? Because it inevitably leads to significant 00:25:21.650 --> 00:25:24.369 stiffness. The shoulder capsule thickens and 00:25:24.369 --> 00:25:27.059 contracts. potentially resulting in a frozen 00:25:27.059 --> 00:25:29.440 shoulder or adhesive capsulitis, which could 00:25:29.440 --> 00:25:32.220 be incredibly difficult to recover from. So the 00:25:32.220 --> 00:25:35.019 non -operative protocol needs to transition relatively 00:25:35.019 --> 00:25:38.319 quickly into a phase of progressive, supervised 00:25:38.319 --> 00:25:41.420 physical therapy and rehabilitation. As early 00:25:41.420 --> 00:25:44.819 as, say, 10 to 14 days after the injury, once 00:25:44.819 --> 00:25:47.400 the very acute pain starts to settle, patients 00:25:47.400 --> 00:25:49.740 are often encouraged to begin gentle range of 00:25:49.740 --> 00:25:52.700 motion exercises such as pendulum exercises as 00:25:52.700 --> 00:25:55.039 their pain allows. Pendulum exercises. That's 00:25:55.039 --> 00:25:57.420 just letting the arm hang down and gently swinging 00:25:57.420 --> 00:26:00.500 it. Exactly. Using gravity to create some gentle 00:26:00.500 --> 00:26:02.980 movement at the shoulder joint without actively 00:26:02.980 --> 00:26:05.710 using the muscles. This helps prevent the capsule 00:26:05.710 --> 00:26:08.609 from seizing up. Okay. Then active assisted range 00:26:08.609 --> 00:26:10.549 of motion where the patient uses their good hand 00:26:10.549 --> 00:26:13.369 or a therapist helps to move the injured arm 00:26:13.369 --> 00:26:15.670 typically begins around four to six weeks once 00:26:15.670 --> 00:26:17.569 the initial pain is subsided further and there's 00:26:17.569 --> 00:26:20.190 some early biological healing starting full active 00:26:20.190 --> 00:26:22.569 range of motion using their own muscles and then 00:26:22.569 --> 00:26:25.230 strengthening exercises follow on from that gradually 00:26:25.230 --> 00:26:27.549 increasing in intensity as the bone continues 00:26:27.549 --> 00:26:30.950 to heal and symptoms improve. It requires significant 00:26:30.950 --> 00:26:34.190 patient buy -in though. Diligence is key. And 00:26:34.190 --> 00:26:36.569 a good rehabilitation team is vital, as noted 00:26:36.569 --> 00:26:39.410 in Unknown 19. Pain management throughout this 00:26:39.410 --> 00:26:41.849 whole process is also absolutely critical to 00:26:41.849 --> 00:26:44.529 allow participation in therapy. How long does 00:26:44.529 --> 00:26:47.109 the bone itself take to heal? The bone itself 00:26:47.109 --> 00:26:49.029 usually takes roughly three to four months to 00:26:49.029 --> 00:26:51.869 achieve solid biological healing, or union, according 00:26:51.869 --> 00:26:54.950 to the OTA. But, and this is important, regaining 00:26:54.950 --> 00:26:57.750 full function, the movement and strength often 00:26:57.750 --> 00:27:00.259 takes considerably longer. Okay, so non -operative 00:27:00.259 --> 00:27:02.660 is the main path for most, focusing heavily on 00:27:02.660 --> 00:27:05.460 early movement and diligent rehab. When is surgery 00:27:05.460 --> 00:27:07.920 indicated then? When do clinicians decide that 00:27:07.920 --> 00:27:10.119 the risks and costs of operating are actually 00:27:10.119 --> 00:27:13.089 outweighed by the potential benefits? Surgery 00:27:13.089 --> 00:27:15.289 is generally reserved for those fractures that 00:27:15.289 --> 00:27:17.990 are significantly displaced beyond those near 00:27:17.990 --> 00:27:20.970 thresholds or fractures that are inherently unstable 00:27:20.970 --> 00:27:24.109 or ones that involve specific patterns that are 00:27:24.109 --> 00:27:26.710 considered unlikely to heal well or restore adequate 00:27:26.710 --> 00:27:28.950 function if they're just left in the sling. Right. 00:27:28.970 --> 00:27:31.210 The decision is also very heavily influenced 00:27:31.210 --> 00:27:33.730 by patient factors. We have to consider their 00:27:33.730 --> 00:27:37.089 age, their overall health, their functional demands. 00:27:37.410 --> 00:27:39.049 What do they need to be able to do with that 00:27:39.049 --> 00:27:41.589 arm? Their general activity level, the quality 00:27:41.589 --> 00:27:44.470 of their bone, Is it strong or osteoporotic? 00:27:44.849 --> 00:27:47.230 And even things like their hand dominance. Okay. 00:27:47.509 --> 00:27:50.549 For example, a young active person with a significantly 00:27:50.549 --> 00:27:53.490 displaced three -part fracture is much more likely 00:27:53.490 --> 00:27:56.150 to benefit from surgery aimed at restoring the 00:27:56.150 --> 00:27:58.650 anatomy as perfectly as possible to give them 00:27:58.650 --> 00:28:00.809 the best chance of optimal long -term function. 00:28:01.570 --> 00:28:04.029 That might be different compared to, say, an 00:28:04.029 --> 00:28:06.470 older, less active individual with lower functional 00:28:06.470 --> 00:28:09.089 demands and perhaps poorer bone quality where 00:28:09.089 --> 00:28:11.269 the risks of surgery might be higher and the 00:28:11.269 --> 00:28:13.789 potential gains less critical for their lifestyle. 00:28:14.130 --> 00:28:16.750 Makes sense. StatPearls and OrthoBullets outline 00:28:16.750 --> 00:28:19.450 several main surgical options, each with its 00:28:19.450 --> 00:28:22.450 own specific indications, advantages, and potential 00:28:22.450 --> 00:28:24.690 drawbacks. Okay, let's try and walk through the 00:28:24.690 --> 00:28:26.690 main surgical strategies then. It sounds like 00:28:26.690 --> 00:28:28.309 there are different approaches for different 00:28:28.309 --> 00:28:30.289 types of break or maybe different types of patient. 00:28:30.589 --> 00:28:33.589 Exactly. It's all about tailoring the solution 00:28:33.589 --> 00:28:36.369 to the specific problem and also to the capabilities 00:28:36.369 --> 00:28:39.369 of the system, meaning the patient's bone quality, 00:28:39.829 --> 00:28:42.230 their overall health, their ability to participate 00:28:42.230 --> 00:28:45.630 in rehab, and so on. One option is closed reduction 00:28:45.630 --> 00:28:49.190 and percutaneous pinning, CRPP. Closed reduction, 00:28:49.730 --> 00:28:52.450 meaning no big cut. That's right. It involves 00:28:52.450 --> 00:28:54.869 manipulating the bone fragments back into a better 00:28:54.869 --> 00:28:57.890 alignment without making a large surgical incision, 00:28:58.109 --> 00:29:00.289 closed reduction, and then holding them in that 00:29:00.289 --> 00:29:03.430 position using metal pins or sometimes wires 00:29:03.430 --> 00:29:05.609 which are inserted through small poke holes in 00:29:05.609 --> 00:29:08.430 the skin, percutaneous pinning. Okay. When would 00:29:08.430 --> 00:29:10.880 that be used? It's often considered for certain 00:29:10.880 --> 00:29:13.299 two -parter or maybe some three -part surgical 00:29:13.299 --> 00:29:15.839 neck fractures, or occasionally specific four 00:29:15.839 --> 00:29:18.180 -part fractures, particularly in patients who 00:29:18.180 --> 00:29:21.039 have good quality bone where the fragments can 00:29:21.039 --> 00:29:23.579 be manipulated back into place relatively easily 00:29:23.579 --> 00:29:26.599 and are expected to hold with just pins. What 00:29:26.599 --> 00:29:29.119 are the sort of pros and cons of that approach? 00:29:29.500 --> 00:29:32.039 Well, the main advantage is that it's less invasive 00:29:32.039 --> 00:29:35.099 than open surgery. That potentially means a quicker 00:29:35.099 --> 00:29:37.519 initial recovery, less disruption to the blood 00:29:37.519 --> 00:29:40.720 supply. Right. But the fixation isn't as mechanically 00:29:40.720 --> 00:29:44.519 strong or rigid as using plates and screws. OrthoBullets 00:29:44.519 --> 00:29:46.960 notes that CRPP can have higher rates of certain 00:29:46.960 --> 00:29:50.059 complications, like pin -side infections or loss 00:29:50.059 --> 00:29:51.900 of reduction, meaning the bone slipping out of 00:29:51.900 --> 00:29:54.039 place again after surgery compared to other methods. 00:29:54.960 --> 00:29:56.920 And as we discussed earlier, the axillary nerve 00:29:56.920 --> 00:29:59.119 is definitely at risk, particularly with pins 00:29:59.119 --> 00:30:02.039 placed from the lateral or outer side. OK. What 00:30:02.039 --> 00:30:04.380 about using plates and screws? That sounds like 00:30:04.380 --> 00:30:07.059 a much more rigid way to hold everything together. 00:30:07.319 --> 00:30:10.440 It is. That's open reduction and internal fixation, 00:30:10.660 --> 00:30:13.819 or IF. This is a more direct approach. It involves 00:30:13.819 --> 00:30:16.559 making a surgical incision, exposing the fracture 00:30:16.559 --> 00:30:19.539 site, open reduction, carefully putting the bone 00:30:19.539 --> 00:30:21.599 fragments back together like a jigsaw puzzle 00:30:21.599 --> 00:30:24.279 under direct vision, and then fixing them firmly 00:30:24.279 --> 00:30:27.319 in place using anatomically pre -contoured metal 00:30:27.319 --> 00:30:30.059 plates and screws. Okay. This is often indicated 00:30:30.059 --> 00:30:33.019 for displays two, three, and particularly some 00:30:33.019 --> 00:30:35.740 four -part fractures, especially those displaced 00:30:35.740 --> 00:30:38.579 surgical neck fractures and significantly displaced 00:30:38.579 --> 00:30:41.420 tuberosity fractures. Remember those needing 00:30:41.420 --> 00:30:43.579 to be pulled back down if displaced more than 00:30:43.579 --> 00:30:46.200 five millimeter. It's often the preferred method 00:30:46.200 --> 00:30:48.480 in younger patients where restoring the precise 00:30:48.480 --> 00:30:50.720 anatomy is considered critical for optimal long 00:30:50.720 --> 00:30:53.680 -term function. Unknown 19 mentions it's typically 00:30:53.680 --> 00:30:55.859 aimed at younger patients or those where the 00:30:55.859 --> 00:30:57.579 fragments are distinct and manageable enough 00:30:57.579 --> 00:31:00.059 to piece back together. Are there specific technical 00:31:00.059 --> 00:31:02.859 challenges with using plates and screws in this 00:31:02.859 --> 00:31:05.480 particular bone, the humerus? Yes, absolutely. 00:31:05.839 --> 00:31:07.759 Especially given that many of these fractures, 00:31:07.799 --> 00:31:10.299 the low -energy ones, occur in older patients 00:31:10.299 --> 00:31:12.559 who often have osteoporotic bone. Meaning the 00:31:12.559 --> 00:31:15.940 bone is soft? Exactly. Soft and sometimes quite 00:31:15.940 --> 00:31:18.099 brittle, which doesn't provide a very strong 00:31:18.099 --> 00:31:21.619 grip for the screws. Orthobolus goes into significant 00:31:21.619 --> 00:31:24.509 detail on this. A key challenge is providing 00:31:24.509 --> 00:31:26.990 adequate support on the inner or medial side 00:31:26.990 --> 00:31:29.369 of the humerus. Why is that side so important? 00:31:29.730 --> 00:31:31.849 Because without good support there, the humeral 00:31:31.849 --> 00:31:34.589 head has a tendency to collapse or shift downwards 00:31:34.589 --> 00:31:37.009 and inwards into what we call a varus position, 00:31:37.529 --> 00:31:39.369 especially if the bone is shattered underneath, 00:31:39.670 --> 00:31:42.980 combinated. This varus collapse is a common failure 00:31:42.980 --> 00:31:46.019 mechanism. Right. So surgeons use specific techniques 00:31:46.019 --> 00:31:48.680 to try and prevent this. They might place a specific 00:31:48.680 --> 00:31:51.460 screw, called a calcar screw, upwards into a 00:31:51.460 --> 00:31:54.839 denser area of bone on that medial side. Or sometimes, 00:31:55.039 --> 00:31:57.119 particularly in severe convolution, they might 00:31:57.119 --> 00:32:00.039 even use a piece of donor bone, often a strut 00:32:00.039 --> 00:32:02.220 graft taken from the patient's fibula, lower 00:32:02.220 --> 00:32:04.599 leg bone, and place it alongside the plate to 00:32:04.599 --> 00:32:07.019 act as a buttress, providing that crucial medial 00:32:07.019 --> 00:32:09.720 support. Wow, using bone from the leg. Yes, it 00:32:09.720 --> 00:32:12.400 can provide excellent mechanical support. Even 00:32:12.400 --> 00:32:14.900 with these techniques, screw cutout, where the 00:32:14.900 --> 00:32:16.859 screws lose their grip in the soft bone of the 00:32:16.859 --> 00:32:19.319 humeral head and pull out, remains a significant 00:32:19.319 --> 00:32:22.400 and relatively common complication after locking 00:32:22.400 --> 00:32:25.519 plate fixation. It's reported in maybe up to 00:32:25.519 --> 00:32:29.160 14 % of cases in some series. Careful plate positioning 00:32:29.160 --> 00:32:32.000 is also essential to avoid irritating or damaging 00:32:32.000 --> 00:32:34.799 nearby structures, like the rotator cuff tendons 00:32:34.799 --> 00:32:37.519 or blood vessels. It really sounds like a technically 00:32:37.519 --> 00:32:39.960 demanding surgery, particularly when dealing 00:32:39.960 --> 00:32:42.299 with weaker bone. What about the option of using 00:32:42.299 --> 00:32:45.619 a rod inside the bone instead? Yes, that's intramedullary 00:32:45.619 --> 00:32:48.539 nailing. This involves inserting a specially 00:32:48.539 --> 00:32:51.079 designed metal rod down the hollow central canal, 00:32:51.559 --> 00:32:54.220 the medullary cavity of the humerus. This rod 00:32:54.220 --> 00:32:57.049 crosses the fracture site. Screws are then inserted 00:32:57.049 --> 00:32:59.369 through the bone and into the nail both above 00:32:59.369 --> 00:33:01.430 and below the fracture to lock the fragments 00:33:01.430 --> 00:33:03.990 in the nail together and control rotation. Okay, 00:33:04.109 --> 00:33:06.789 when is nailing used? It's typically used for 00:33:06.789 --> 00:33:09.410 certain fractures of the surgical neck or perhaps 00:33:09.410 --> 00:33:12.710 some specific two or three part fractures. It's 00:33:12.710 --> 00:33:14.529 often considered in younger patients with good 00:33:14.529 --> 00:33:17.349 bone quality or sometimes when there's also a 00:33:17.349 --> 00:33:19.250 fracture further down the humeral shaft that 00:33:19.250 --> 00:33:21.809 needs fixing as well, the nail can potentially 00:33:21.809 --> 00:33:25.069 address both. What are the pros and cons of nailing 00:33:25.069 --> 00:33:27.990 compared to, say, pleating? Well, ortho bullets 00:33:27.990 --> 00:33:30.930 suggest IMN can potentially have favorable healing 00:33:30.930 --> 00:33:33.650 rates and might allow for slightly earlier range 00:33:33.650 --> 00:33:36.150 of motion compared to plates in some cases, as 00:33:36.150 --> 00:33:38.130 it acts more like an internal splint, a load 00:33:38.130 --> 00:33:41.190 sharing device. However, a potential downside 00:33:41.190 --> 00:33:43.769 is the insertion point for the nail. Where does 00:33:43.769 --> 00:33:45.970 it go in? It usually has to be inserted through 00:33:45.970 --> 00:33:48.230 the very top of the humerus, which often requires 00:33:48.230 --> 00:33:51.019 making a split in or going through part of the 00:33:51.019 --> 00:33:53.339 rotator cuff tendons, usually the supraspinatus. 00:33:54.279 --> 00:33:56.380 This necessary violation of the rotator cuff 00:33:56.380 --> 00:33:58.420 can sometimes lead to persistent shoulder pain 00:33:58.420 --> 00:34:01.480 or impingement symptoms after surgery. There 00:34:01.480 --> 00:34:03.960 are also risks to nerves, particularly the axillary 00:34:03.960 --> 00:34:06.180 and radial nerves, with the placement of the 00:34:06.180 --> 00:34:08.579 locking screws used to secure the nail. Okay, 00:34:08.739 --> 00:34:11.079 so different trade -offs again. Now what about 00:34:11.079 --> 00:34:13.219 the most significant intervention, replacing 00:34:13.219 --> 00:34:15.639 the joint entirely? Right, that's arthroplasty, 00:34:15.739 --> 00:34:18.650 or shoulder replacement. This is generally considered 00:34:18.650 --> 00:34:20.869 for the most severe fracture patterns where the 00:34:20.869 --> 00:34:23.530 bone fragments are deemed unlikely to heal reliably, 00:34:24.090 --> 00:34:26.730 perhaps where the articular surface itself is 00:34:26.730 --> 00:34:30.230 badly damaged or split, or, crucially, where 00:34:30.230 --> 00:34:32.409 the blood supply to the humeral head is thought 00:34:32.409 --> 00:34:34.809 to be significantly compromised, leading to a 00:34:34.809 --> 00:34:37.969 very high risk of that avascular necrosis, AVN, 00:34:37.969 --> 00:34:41.690 the bone dying off. It also sometimes uses a 00:34:41.690 --> 00:34:44.250 salvage procedure if other surgical attempts, 00:34:44.329 --> 00:34:47.960 like ORIF, have failed. Arthroplasty is generally 00:34:47.960 --> 00:34:50.500 chosen more frequently for older patients, especially 00:34:50.500 --> 00:34:52.860 those with poorer bone quality, or perhaps those 00:34:52.860 --> 00:34:54.880 who already had significant shoulder arthritis 00:34:54.880 --> 00:34:57.179 or rotator cuff problems even before the fracture. 00:34:57.980 --> 00:35:00.099 The sources describe two main types used for 00:35:00.099 --> 00:35:02.500 fracture. OK, what are they? The first is hemiarthroplasty, 00:35:02.920 --> 00:35:05.699 hemi meaning half. This involves replacing only 00:35:05.699 --> 00:35:08.579 the humeral side of the joint. The ball is replaced 00:35:08.579 --> 00:35:11.380 with a metal prosthesis. The socket side, the 00:35:11.380 --> 00:35:13.699 glenoid on the shoulder blade, is left as it 00:35:13.699 --> 00:35:16.139 is. This might be used in slightly younger patients, 00:35:16.460 --> 00:35:19.380 maybe those aged 40 to 65, with certain fracture 00:35:19.380 --> 00:35:21.940 patterns where the head isn't salvageable, but 00:35:21.940 --> 00:35:24.400 the rotator cuff is still functional. Or it's 00:35:24.400 --> 00:35:26.679 also an option in older patients with severely 00:35:26.679 --> 00:35:29.559 shattered anatomic neck fractures, or four -part 00:35:29.559 --> 00:35:32.320 fractures, as described in sat pearls and ortho 00:35:32.320 --> 00:35:34.519 bullets. What's the main challenge with heme 00:35:34.519 --> 00:35:37.380 arthroplasty for fractures? A really critical 00:35:37.380 --> 00:35:39.559 challenge is getting those tuberosity fragments, 00:35:39.559 --> 00:35:42.119 remember, where the rotator cuff muscles attach 00:35:42.119 --> 00:35:44.940 to heal correctly onto the middle prosthesis 00:35:44.940 --> 00:35:47.820 and in the right position. This is technically 00:35:47.820 --> 00:35:50.940 demanding. If the tuberosities don't heal properly 00:35:50.940 --> 00:35:53.840 or heal in the wrong place, then the rotator 00:35:53.840 --> 00:35:56.679 cuff function is compromised, which can significantly 00:35:56.679 --> 00:35:59.360 limit movement, particularly the ability to rotate 00:35:59.360 --> 00:36:02.710 the arm outwards. Okay. And the other... type 00:36:02.710 --> 00:36:04.349 of replacement, the one that sounds like it's 00:36:04.349 --> 00:36:06.429 becoming more common. Yes, that's the reverse 00:36:06.429 --> 00:36:09.289 total shoulder arthroplasty, RSA. This is being 00:36:09.289 --> 00:36:12.110 used increasingly, particularly in older, perhaps 00:36:12.110 --> 00:36:14.130 less functionally demanding patients with complex 00:36:14.130 --> 00:36:16.809 fractures. It's called reverse because it fundamentally 00:36:16.809 --> 00:36:19.369 alters the shoulder's normal biomechanics. In 00:36:19.369 --> 00:36:21.690 a standard shoulder replacement, you replace 00:36:21.690 --> 00:36:24.969 the ball with a metal ball and the socket with 00:36:24.969 --> 00:36:28.489 a plastic socket. In an RSA, you actually put 00:36:28.489 --> 00:36:31.110 the ball component onto the shoulder blade side 00:36:31.110 --> 00:36:33.670 on the glenoid socket, and you put a socket component 00:36:33.670 --> 00:36:36.809 onto the top of the humeral bone. It flips the 00:36:36.809 --> 00:36:39.150 joint around. Exactly. It effectively reverses 00:36:39.150 --> 00:36:41.820 the ball and socket. The clever thing about this 00:36:41.820 --> 00:36:44.079 design is that it allows the large deltoid muscle 00:36:44.079 --> 00:36:46.440 on the outside of the shoulder to become the 00:36:46.440 --> 00:36:49.420 primary elevator of the arm, effectively bypassing 00:36:49.420 --> 00:36:52.300 the need for a functional rotator cuff. Ah, I 00:36:52.300 --> 00:36:54.539 see. So it's indicated in elderly patients with 00:36:54.539 --> 00:36:56.659 very complex fractures, especially four -part 00:36:56.659 --> 00:36:59.400 fractures, those where the tuberosities are shattered 00:36:59.400 --> 00:37:02.519 beyond repair, non -reconstructable, those with 00:37:02.519 --> 00:37:04.900 very poor bone stock making fixation difficult, 00:37:04.960 --> 00:37:07.960 or importantly, those who already had large irreparable 00:37:07.960 --> 00:37:09.719 rotator cuff tears before they even broke. their 00:37:09.719 --> 00:37:12.960 shoulder. So the RSA is chosen when the normal 00:37:12.960 --> 00:37:15.800 engine for lifting the arm the rotator cuff is 00:37:15.800 --> 00:37:18.579 damaged or can't be relied upon and it essentially 00:37:18.579 --> 00:37:20.659 leverages a different engine the deltoid muscle 00:37:20.659 --> 00:37:22.699 to do the work. That's a very good way to think 00:37:22.699 --> 00:37:25.420 about it, yes. It shifts the joint's center of 00:37:25.420 --> 00:37:28.119 rotation downwards and inwards, which tensions 00:37:28.119 --> 00:37:30.760 the deltoid muscle fibers more effectively, allowing 00:37:30.760 --> 00:37:33.519 them to lift the arm even without a working rotator 00:37:33.519 --> 00:37:36.420 cuff. Interesting. OrthoBullets notes that even 00:37:36.420 --> 00:37:39.159 when doing an RSA for fracture, attempting to 00:37:39.159 --> 00:37:41.599 repair the greater tuberosity fragment back to 00:37:41.599 --> 00:37:44.000 the prosthesis is still generally recommended 00:37:44.000 --> 00:37:47.139 if possible, as it seems to improve the overall 00:37:47.139 --> 00:37:49.400 range of motion, particularly rotation. Okay. 00:37:50.269 --> 00:37:52.809 stat pearls adds an interesting observation. 00:37:53.630 --> 00:37:55.969 RSA performed as a primary procedure for a bad 00:37:55.969 --> 00:37:58.690 fracture or perhaps after failed non -operative 00:37:58.690 --> 00:38:01.489 management might actually yield better functional 00:38:01.489 --> 00:38:04.650 outcomes than RSA performed as a salvage procedure 00:38:04.650 --> 00:38:07.429 after a failed attempt at ORIF with plates and 00:38:07.429 --> 00:38:10.769 screws. Why might that be? The thinking is perhaps 00:38:10.769 --> 00:38:12.929 there's less scarring and damage to the surrounding 00:38:12.929 --> 00:38:14.909 muscles and tissues in the non -operative group 00:38:14.909 --> 00:38:17.210 compared to those who've had a previous complex 00:38:17.210 --> 00:38:19.480 open surgery that didn't succeed. It's really 00:38:19.480 --> 00:38:21.420 clear there's no single best treatment then. 00:38:21.619 --> 00:38:23.699 It's all about carefully matching the intervention 00:38:23.699 --> 00:38:26.500 to the specific patient, the specific fracture 00:38:26.500 --> 00:38:29.260 pattern, and the predicted likelihood of success 00:38:29.260 --> 00:38:31.239 with the different methods, considering all those 00:38:31.239 --> 00:38:34.760 risks and benefits. Which brings us to the journey 00:38:34.760 --> 00:38:38.039 after the initial treatment, the road to recovery. 00:38:38.719 --> 00:38:40.440 This sounds like it's probably a marathon, not 00:38:40.440 --> 00:38:43.480 a sprint. Absolutely. That's a very apt description. 00:38:44.039 --> 00:38:46.420 Whether treated nonoperatively with just a sling 00:38:46.420 --> 00:38:49.219 or operatively with complex metalwork, recovery 00:38:49.219 --> 00:38:52.019 from a proximal humerus fracture is often a lengthy 00:38:52.019 --> 00:38:54.119 and demanding process for the patient. Right. 00:38:54.360 --> 00:38:56.360 While the bone itself might achieve biological 00:38:56.360 --> 00:38:58.619 union, as we said, in maybe three to four months, 00:38:58.800 --> 00:39:01.699 according to the OTA, regaining full or even 00:39:01.699 --> 00:39:04.280 near full pain -free range of motion, strength, 00:39:04.460 --> 00:39:06.679 and functional independence takes significantly 00:39:06.679 --> 00:39:09.159 longer, often six months to a year and sometimes 00:39:09.159 --> 00:39:12.079 even more. That's a really substantial commitment 00:39:12.079 --> 00:39:15.159 of time and effort. What makes the recovery so 00:39:15.159 --> 00:39:17.579 particularly challenging with this injury? Well, 00:39:17.659 --> 00:39:20.619 several factors contribute. Pain is often prolonged, 00:39:20.900 --> 00:39:23.139 especially in the early stages, and managing 00:39:23.139 --> 00:39:26.039 it effectively is key to enabling refabilitation. 00:39:26.800 --> 00:39:29.840 Stiffness is a major, major hurdle. Stiffness? 00:39:30.059 --> 00:39:32.519 Yes. The shoulder joint is notoriously prone 00:39:32.519 --> 00:39:35.059 to developing adhesive capsulitis, that frozen 00:39:35.059 --> 00:39:37.599 shoulder, after almost any significant injury 00:39:37.599 --> 00:39:40.699 or period of immobilization. And this can happen 00:39:40.699 --> 00:39:42.760 regardless of whether it was treated non -operatively 00:39:42.760 --> 00:39:45.739 or operatively. Regaining strength in the shoulder 00:39:45.739 --> 00:39:48.440 and arm muscles, which weaken very rapidly with 00:39:48.440 --> 00:39:51.539 disuse, requires dedicated, consistent effort 00:39:51.539 --> 00:39:55.380 over many months. And unknown 19 also highlights 00:39:55.380 --> 00:39:58.360 something important. The significant emotional 00:39:58.360 --> 00:40:00.820 and psychological impact these injuries can have. 00:40:01.119 --> 00:40:03.219 How so? Think about the loss of independence. 00:40:03.480 --> 00:40:06.420 the inability to perform simple daily tasks like 00:40:06.420 --> 00:40:09.119 dressing or cooking, the persistent pain, and 00:40:09.119 --> 00:40:11.579 sometimes the frustratingly slow pace of recovery. 00:40:11.940 --> 00:40:14.000 This can understandably lead to frustration, 00:40:14.260 --> 00:40:16.539 anxiety, and sometimes even depression, which 00:40:16.539 --> 00:40:19.260 in turn can impact motivation for rehab. So that 00:40:19.260 --> 00:40:21.119 diligent physical therapy we talked about earlier 00:40:21.119 --> 00:40:23.159 isn't just recommended. It sounds absolutely 00:40:23.159 --> 00:40:25.880 essential. It is absolutely non -negotiable. 00:40:26.219 --> 00:40:28.340 You simply won't get the best possible outcome 00:40:28.340 --> 00:40:31.599 without it. A structured progressive rehabilitation 00:40:31.599 --> 00:40:35.000 program guided by a physiotherapist is the cornerstone 00:40:35.000 --> 00:40:37.099 of recovery, whether the fracture was treated 00:40:37.099 --> 00:40:39.420 with a sling or with the most complex surgery. 00:40:40.260 --> 00:40:42.340 OrthoBullets describes a typical multi -phase 00:40:42.340 --> 00:40:45.679 program, starting with those gentle, often passive 00:40:45.679 --> 00:40:48.539 or pendulum range of motion exercises very early 00:40:48.539 --> 00:40:51.199 on, progressing carefully to active assisted 00:40:51.199 --> 00:40:53.340 and then full active range of motion as healing 00:40:53.340 --> 00:40:56.829 allows and pain settles. And finally, incorporating 00:40:56.829 --> 00:40:59.230 progressive strengthening exercises for the rotator 00:40:59.230 --> 00:41:01.949 cuff, deltoid, and scapular stabilizing muscles, 00:41:02.530 --> 00:41:04.489 along with more advanced functional exercises 00:41:04.489 --> 00:41:07.469 relevant to the patient's goals. Without this 00:41:07.469 --> 00:41:10.030 commitment to physical therapy, significant stiffness 00:41:10.030 --> 00:41:12.809 and lasting limitations in movement are almost 00:41:12.809 --> 00:41:15.070 guaranteed. This is stressed across all the main 00:41:15.070 --> 00:41:18.139 sources, the OTA or the bullets unknown 19. What 00:41:18.139 --> 00:41:20.559 are the potential long -term outcomes then, even 00:41:20.559 --> 00:41:22.719 assuming successful treatment and good rehab? 00:41:23.159 --> 00:41:25.079 Are there often lingering issues people should 00:41:25.079 --> 00:41:27.460 be aware of? While most patients will certainly 00:41:27.460 --> 00:41:30.599 see significant improvement over time, it is 00:41:30.599 --> 00:41:32.760 important to manage expectations realistically. 00:41:33.760 --> 00:41:36.179 Full restoration back to exactly the pre -injury 00:41:36.179 --> 00:41:39.659 level of function isn't always achieved, particularly 00:41:39.659 --> 00:41:42.340 with the more complex fracture patterns, or often 00:41:42.340 --> 00:41:46.159 in older patients. The OTA mentions that persistent 00:41:46.159 --> 00:41:49.139 stiffness, perhaps not regaining the last few 00:41:49.139 --> 00:41:52.199 degrees of motion, some degree of ongoing soreness 00:41:52.199 --> 00:41:54.699 or pain, particularly with certain activities 00:41:54.699 --> 00:41:57.280 or weather changes, and maybe not quite regaining 00:41:57.280 --> 00:41:59.559 the original level of strength, these are not 00:41:59.559 --> 00:42:02.500 uncommon long -term outcomes. The shoulder might 00:42:02.500 --> 00:42:04.699 just feel and move a bit differently than it 00:42:04.699 --> 00:42:07.460 did before the injury, even years later. And 00:42:07.460 --> 00:42:09.780 beyond just those lingering symptoms, what about 00:42:09.780 --> 00:42:12.199 actual complications that can arise, either during 00:42:12.199 --> 00:42:14.579 healing or later on? We touched on some earlier, 00:42:14.679 --> 00:42:17.679 like nerve injury or infection. Yes. Unfortunately, 00:42:17.820 --> 00:42:19.619 complications can occur with both non -operative 00:42:19.619 --> 00:42:21.980 and operative management, and they can obviously 00:42:21.980 --> 00:42:24.619 significantly impact the final outcome, sometimes 00:42:24.619 --> 00:42:26.860 requiring further intervention. Drawing from 00:42:26.860 --> 00:42:28.900 the information in StatPearls, OrthoBullets, 00:42:28.980 --> 00:42:31.800 and Unknown19, the potential complications include 00:42:31.800 --> 00:42:34.440 quite a range. Non -union. This is where the 00:42:34.440 --> 00:42:37.739 bone simply fails to heal completely. Orthobolus 00:42:37.739 --> 00:42:40.400 states, this is perhaps most common after two 00:42:40.400 --> 00:42:43.019 -part surgical neck fractures, and risk factors 00:42:43.019 --> 00:42:45.960 include being older, being a smoker, and significant 00:42:45.960 --> 00:42:48.880 displacement initially. Melunian, this means 00:42:48.880 --> 00:42:52.179 the bone does heal, but it heals in a poor or 00:42:52.179 --> 00:42:54.699 abnormal position, maybe with significant angulation 00:42:54.699 --> 00:42:58.519 or displacement remaining. A malunited greater 00:42:58.519 --> 00:43:00.739 tuberosity fragment, for instance, healing too 00:43:00.739 --> 00:43:03.500 high, is a classic cause of chronic pain and 00:43:03.500 --> 00:43:06.159 impingement of the rotator cuff tendons when 00:43:06.159 --> 00:43:09.960 lifting the arm of vascular necrosis, AVN. I 00:43:09.960 --> 00:43:11.940 mentioned this. The blood supply to the humeral 00:43:11.940 --> 00:43:14.380 head gets disrupted by the fracture lines, causing 00:43:14.380 --> 00:43:16.800 the bone tissue in the head to die. This can 00:43:16.800 --> 00:43:18.639 lead to the head collapsing or fragmenting over 00:43:18.639 --> 00:43:21.500 time, causing pain and arthritis. It's a significant 00:43:21.500 --> 00:43:23.860 risk, particularly in those four -part fractures 00:43:23.860 --> 00:43:26.300 and anatomic neck fractures, precisely because 00:43:26.300 --> 00:43:28.340 the fracture lines run through areas critical 00:43:28.340 --> 00:43:30.880 for blood supply. Stiffness Adhesive Capsulitis, 00:43:31.179 --> 00:43:33.739 that frozen shoulder we discussed, a significant 00:43:33.739 --> 00:43:36.539 loss of range of motion due to scarring and thickening 00:43:36.539 --> 00:43:38.940 of the joint capsule. This is a risk in almost 00:43:38.940 --> 00:43:41.840 any significant shoulder injury or surgery, but 00:43:42.000 --> 00:43:44.920 particularly common after fractures due to the 00:43:44.920 --> 00:43:48.000 initial trauma and necessary periods of immobilization. 00:43:48.000 --> 00:43:50.980 Okay. Nerve injury. While some nerve issues might 00:43:50.980 --> 00:43:53.400 be present right from the initial injury, nerve 00:43:53.400 --> 00:43:56.059 damage can also occur during surgery or sometimes 00:43:56.059 --> 00:43:58.780 nerve function doesn't recover fully. The axillary 00:43:58.780 --> 00:44:01.579 nerve is the most commonly affected. Radial and 00:44:01.579 --> 00:44:04.139 musculocutaneous nerve injuries are less common, 00:44:04.340 --> 00:44:06.780 but certainly possible. Hardware complications. 00:44:07.340 --> 00:44:09.900 These are specific to operative treatment involving 00:44:09.900 --> 00:44:13.440 plates, screws, pins, or nails. Examples include 00:44:13.440 --> 00:44:15.679 that screw cut out from the bone, especially 00:44:15.679 --> 00:44:18.300 with plates in poor quality osteoporotic bone. 00:44:19.199 --> 00:44:21.980 Hardware can also loosen over time, break, or 00:44:21.980 --> 00:44:24.119 sometimes just become prominent or irritating, 00:44:24.280 --> 00:44:27.760 requiring removal later on. Infection. Always 00:44:27.760 --> 00:44:30.039 a risk with any surgery, though thankfully relatively 00:44:30.039 --> 00:44:32.340 low with modern techniques, it can be devastating 00:44:32.340 --> 00:44:34.820 if it occurs, often requiring further operations. 00:44:35.239 --> 00:44:37.980 Post -traumatic arthritis. Arthritis can develop 00:44:37.980 --> 00:44:40.260 in the shoulder joint over time, sometimes years 00:44:40.260 --> 00:44:42.599 later, especially if the original fracture involved 00:44:42.599 --> 00:44:45.179 the articular surface, or if there was a malunion 00:44:45.179 --> 00:44:49.019 or AVN that altered the joint mechanics. And 00:44:49.019 --> 00:44:51.219 these complications, particularly things like 00:44:51.219 --> 00:44:54.230 painful non -union, Malunion, AVN, or severe 00:44:54.230 --> 00:44:57.269 stiffness can sometimes necessitate further surgery 00:44:57.269 --> 00:44:59.909 down the line. Often, this might involve converting 00:44:59.909 --> 00:45:02.409 to a salvage shoulder replacement, particularly 00:45:02.409 --> 00:45:04.929 in older individuals, if the pain dysfunction 00:45:04.929 --> 00:45:07.329 are severe enough. It really highlights that 00:45:07.329 --> 00:45:09.809 fixing the initial break is just the very beginning, 00:45:09.949 --> 00:45:12.329 isn't it? Managing the whole biological and mechanical 00:45:12.329 --> 00:45:14.590 environment to get successful healing and good 00:45:14.590 --> 00:45:17.630 long -term function is incredibly complex. It 00:45:17.630 --> 00:45:19.949 also underscores the need for expertise right 00:45:19.949 --> 00:45:23.969 at the start. diagnosis. What else could potentially 00:45:23.969 --> 00:45:26.469 cause similar symptoms that might be mistaken 00:45:26.469 --> 00:45:29.730 for a proximal humerus fracture initially? That's 00:45:29.730 --> 00:45:33.449 a critical point for clinicians. Yes, being able 00:45:33.449 --> 00:45:36.050 to distinguish a fracture from other potential 00:45:36.050 --> 00:45:38.170 sources of severe shoulder pain and dysfunction 00:45:38.170 --> 00:45:42.159 is step one. StatProls provides quite an extensive 00:45:42.159 --> 00:45:44.119 list of these differential diagnoses that must 00:45:44.119 --> 00:45:46.360 be considered. It's a bit like ensuring you're 00:45:46.360 --> 00:45:48.539 diagnosing the correct root cause of a business 00:45:48.539 --> 00:45:50.860 problem before you jump to proposing a solution. 00:45:51.340 --> 00:45:53.380 Right. What sorts of things are on that list? 00:45:53.440 --> 00:45:55.980 What else could it be? Well, it's quite broad, 00:45:56.099 --> 00:45:57.820 as you might imagine. It certainly encompasses 00:45:57.820 --> 00:46:00.440 other traumatic injuries right around the shoulder 00:46:00.440 --> 00:46:03.320 complex. Things like dislocations of the main 00:46:03.320 --> 00:46:05.460 shoulder joint itself, which can actually occur 00:46:05.460 --> 00:46:07.659 with fractures, complicating things further, 00:46:07.940 --> 00:46:10.489 or fractures of the clavicle. the collarbone, 00:46:10.929 --> 00:46:13.909 or the scapula, the shoulder blade. But it also 00:46:13.909 --> 00:46:16.750 includes a wide range of non -bony injuries and 00:46:16.750 --> 00:46:18.469 conditions that can cause significant shoulder 00:46:18.469 --> 00:46:21.489 pain. Rotator cuff pathology. This is a big one. 00:46:21.650 --> 00:46:24.190 It includes acute tears, maybe partial or full 00:46:24.190 --> 00:46:26.849 -thickness tears caused by the same trauma that 00:46:26.849 --> 00:46:29.409 might have caused a fracture. Or it could be 00:46:29.409 --> 00:46:31.829 chronic issues like tendonitis or impingement 00:46:31.829 --> 00:46:34.329 syndromes where the tendons are getting pinched. 00:46:34.409 --> 00:46:36.670 Degenerative conditions, things like pre -existing 00:46:36.670 --> 00:46:39.030 or developing glenohumeral arthritis, just wear 00:46:39.030 --> 00:46:42.010 and tear of the joint surface, or even avascular 00:46:42.010 --> 00:46:44.929 necrosis, AVN, occurring independently of any 00:46:44.929 --> 00:46:48.369 recent trauma. Capsular issues. Adhesive capsulitis, 00:46:48.449 --> 00:46:51.590 that frozen shoulder again. Sometimes the onset 00:46:51.590 --> 00:46:53.909 can be relatively sudden, making it difficult 00:46:53.909 --> 00:46:55.829 to differentiate from the stiffness following 00:46:55.829 --> 00:46:58.610 a fracture initially, although the history of 00:46:58.610 --> 00:47:02.070 injury is usually different. Biceps, tendon problems, 00:47:02.570 --> 00:47:04.670 things like inflammation, tendonitis, or even 00:47:04.670 --> 00:47:06.570 ruptures of the long head of the biceps tendon 00:47:06.570 --> 00:47:09.429 where it runs near the shoulder joint, acromioclavicular 00:47:09.429 --> 00:47:12.170 joint issues, the joint at the top of the shoulder 00:47:12.170 --> 00:47:14.110 where the collarbone meets the shoulder blade. 00:47:14.239 --> 00:47:17.699 Things like AC joint separation from a fall or 00:47:17.699 --> 00:47:20.280 just arthritis in that joint. Shoulder instability. 00:47:21.000 --> 00:47:23.079 Patients might have recurrent dislocations or 00:47:23.079 --> 00:47:25.480 just a general feeling of looseness called multi 00:47:25.480 --> 00:47:28.719 -directional instability. And then less common, 00:47:29.039 --> 00:47:31.380 but still possible, are neurovascular issues 00:47:31.380 --> 00:47:34.739 presenting primarily as pain. Things like nerve 00:47:34.739 --> 00:47:36.820 entrapments, perhaps superscapular neuropathy, 00:47:37.219 --> 00:47:39.820 affecting the rotator cuff muscles, or thoracic 00:47:39.820 --> 00:47:41.719 outlet syndrome affecting nerves and vessels 00:47:41.719 --> 00:47:45.079 as they leave the neck. Or, very rarely, vascular 00:47:45.079 --> 00:47:47.900 events like subclavian artery thrombosis. So 00:47:47.900 --> 00:47:50.780 quite a significant overlap in potential symptoms, 00:47:51.099 --> 00:47:53.119 then, really requiring a systematic approach 00:47:53.119 --> 00:47:55.500 to diagnosis using the patient's history, the 00:47:55.500 --> 00:47:57.820 physical exam findings, and then targeted imaging 00:47:57.820 --> 00:48:00.599 to confirm. Precisely. A thorough evaluation 00:48:00.599 --> 00:48:03.000 is absolutely essential to pinpoint the exact 00:48:03.000 --> 00:48:04.800 name the nature of the injury or the condition 00:48:04.800 --> 00:48:07.340 causing the symptoms. This is why self -diagnosis 00:48:07.340 --> 00:48:09.980 for severe shoulder pain is really risky. And 00:48:09.980 --> 00:48:12.380 getting an expert clinical assessment is paramount. 00:48:12.699 --> 00:48:15.320 And as Stat Pearls notes, optimal management 00:48:15.320 --> 00:48:17.539 requires more than just understanding the injury 00:48:17.539 --> 00:48:20.039 itself. It requires tailoring the treatment plan 00:48:20.039 --> 00:48:22.400 very carefully to the individual patient, considering 00:48:22.400 --> 00:48:25.019 their age, their functional status, their hand 00:48:25.019 --> 00:48:27.679 dominance, their overall health, and any other 00:48:27.679 --> 00:48:30.059 medical problems, even their social situation 00:48:30.059 --> 00:48:32.860 and support network, and crucially, personal 00:48:32.860 --> 00:48:35.820 goals and expectations for recovery. It has to 00:48:35.820 --> 00:48:38.480 be a holistic assessment, not just focusing narrowly 00:48:38.480 --> 00:48:41.900 on the broken bone. This comprehensive approach 00:48:41.900 --> 00:48:43.800 to managing these injuries, especially when you 00:48:43.800 --> 00:48:46.480 consider how common they are in our aging population, 00:48:47.059 --> 00:48:49.360 feels like it must pose a significant challenge 00:48:49.360 --> 00:48:52.389 for healthcare systems more broadly. Are the 00:48:52.389 --> 00:48:54.889 sources touching upon how the system is grappling 00:48:54.889 --> 00:48:57.610 with this, particularly perhaps the cost aspect? 00:48:57.849 --> 00:49:00.610 They are, yes. And this is a point with significant 00:49:00.610 --> 00:49:02.750 implications that go beyond just this specific 00:49:02.750 --> 00:49:05.969 injury. The StatPearl source in particular highlights 00:49:05.969 --> 00:49:08.429 that proximal humerus fractures, precisely because 00:49:08.429 --> 00:49:10.269 they are common, and the treatment, especially 00:49:10.269 --> 00:49:12.170 surgical treatment and rehab, can be costly, 00:49:12.710 --> 00:49:14.630 are increasingly becoming a focus of health care 00:49:14.630 --> 00:49:17.269 cost containment strategies and alternative payment 00:49:17.269 --> 00:49:20.809 models. Cost containment and alternative payment 00:49:20.809 --> 00:49:23.710 models. What does that actually mean in practice? 00:49:24.630 --> 00:49:27.210 What means that health care systems and the organizations 00:49:27.210 --> 00:49:29.909 that pay for care, like insurers or government 00:49:29.909 --> 00:49:32.750 bodies, are actively looking for ways to manage 00:49:32.750 --> 00:49:35.030 the total costs associated with treating these 00:49:35.030 --> 00:49:37.670 injuries more efficiently and predictably. Right. 00:49:38.030 --> 00:49:40.190 This includes initiatives like bundled payments, 00:49:40.730 --> 00:49:42.909 where a single predetermined payment is made 00:49:42.909 --> 00:49:45.289 to cover all the services related to a specific 00:49:45.289 --> 00:49:48.739 episode of care, say, from the initial fracture 00:49:48.739 --> 00:49:51.079 diagnosis right through several months of recovery 00:49:51.079 --> 00:49:53.739 and rehabilitation, rather than paying for each 00:49:53.739 --> 00:49:56.420 individual doctor visit, x -ray, surgery, therapy 00:49:56.420 --> 00:49:59.059 session separately. Oh, I see. The idea is this 00:49:59.059 --> 00:50:01.260 encourages hospitals and all the providers involved 00:50:01.260 --> 00:50:04.199 to coordinate care more effectively, reduce unnecessary 00:50:04.199 --> 00:50:06.739 variations, and control the overall cost of that 00:50:06.739 --> 00:50:09.699 episode. There's also a growing emphasis on standardizing 00:50:09.699 --> 00:50:12.039 diagnosis, treatment, and rehabilitation pathways 00:50:12.039 --> 00:50:14.519 based on the best available evidence and outcomes 00:50:14.519 --> 00:50:17.940 data. Standardizing care pathways. Does that 00:50:17.940 --> 00:50:21.179 risk creating a sort of one -size -fits -all 00:50:21.179 --> 00:50:23.920 approach, given how much variability there seems 00:50:23.920 --> 00:50:26.260 to be in these fractures and, as you said, in 00:50:26.260 --> 00:50:29.519 the patients themselves? That's exactly the tension, 00:50:29.599 --> 00:50:32.320 isn't it? Yeah. And StatPearls explicitly cautions 00:50:32.320 --> 00:50:35.400 against adopting a rigid one -size -fits -all 00:50:35.400 --> 00:50:38.789 strategy. The goal, ideally, is not to eliminate 00:50:38.789 --> 00:50:40.889 individualized care based on clinical judgment 00:50:40.889 --> 00:50:43.869 and patient needs, but rather it's about using 00:50:43.869 --> 00:50:46.420 big data. aggregating information from large 00:50:46.420 --> 00:50:48.940 patient populations, analyzing outcomes from 00:50:48.940 --> 00:50:50.500 different treatments in different groups through 00:50:50.500 --> 00:50:52.760 research studies to identify best practices, 00:50:53.019 --> 00:50:55.000 understand risk factors better, and determine 00:50:55.000 --> 00:50:56.960 which treatments tend to be most effective and 00:50:56.960 --> 00:50:59.099 cost effective for different patient profiles 00:50:59.099 --> 00:51:01.940 and fracture types. This population -level knowledge 00:51:01.940 --> 00:51:03.780 should then inform what they call customized 00:51:03.780 --> 00:51:06.300 application at the level of the hospital or clinic 00:51:06.300 --> 00:51:08.599 and ultimately at the individual patient level. 00:51:08.719 --> 00:51:11.719 So, using the big -picture data to help refine 00:51:11.719 --> 00:51:14.099 individual treatment decisions, rather than dictating 00:51:14.099 --> 00:51:16.780 them rigidly from the top down. Exactly. It's 00:51:16.780 --> 00:51:18.719 about establishing evidence -based guidelines 00:51:18.719 --> 00:51:21.300 and protocols that can guide decision -making 00:51:21.300 --> 00:51:24.360 and reduce unwarranted variation, while still 00:51:24.360 --> 00:51:26.760 allowing clinicians the flexibility to exercise 00:51:26.760 --> 00:51:29.079 their judgment and incorporate patient preferences. 00:51:30.280 --> 00:51:32.719 But achieving this effectively requires really 00:51:32.719 --> 00:51:35.500 strong active communication and collaboration 00:51:35.500 --> 00:51:38.380 among the entire healthcare team. The whole team. 00:51:38.559 --> 00:51:41.420 Yes, the orthopedic surgeons, the anesthetists, 00:51:41.659 --> 00:51:44.800 nurses, physical therapists, occupational therapists, 00:51:45.320 --> 00:51:47.800 perhaps geriatricians for older patients, social 00:51:47.800 --> 00:51:50.460 workers, case managers, everyone involved needs 00:51:50.460 --> 00:51:52.420 to work together to ensure the patient receives 00:51:52.420 --> 00:51:55.099 coordinated, efficient, and effective care right 00:51:55.099 --> 00:51:57.139 from the moment of injury through their long 00:51:57.139 --> 00:51:59.639 -term recovery. It's a systemic challenge that 00:51:59.639 --> 00:52:02.360 really requires a team -based solution. And just 00:52:02.360 --> 00:52:04.260 going back to those low -energy fractures in 00:52:04.260 --> 00:52:06.400 older patients, StatPearls also notes that the 00:52:06.400 --> 00:52:08.639 fracture itself is effectively a diagnosis of 00:52:08.639 --> 00:52:11.219 compromised bone density, doesn't it? Yes, that's 00:52:11.219 --> 00:52:13.260 a crucial point highlighted in the Pearls section 00:52:13.260 --> 00:52:16.940 of that source. For any older adult who sustains 00:52:16.940 --> 00:52:19.260 a proximal humerus fracture from a simple fall 00:52:19.260 --> 00:52:22.119 or minimal trauma, assessing and addressing their 00:52:22.119 --> 00:52:24.679 underlying bone health, specifically looking 00:52:24.679 --> 00:52:27.579 for osteoporosis, is really non -negotiable. 00:52:28.139 --> 00:52:31.340 Because that fracture acts as a sentinel event. 00:52:31.630 --> 00:52:35.010 It's a major warning sign indicating that the 00:52:35.010 --> 00:52:37.630 patient is at significantly high risk for suffering 00:52:37.630 --> 00:52:40.409 other fragility fractures in the future, particularly 00:52:40.409 --> 00:52:43.030 devastating ones like hip fractures or vertebral 00:52:43.030 --> 00:52:45.269 fractures in the spine or wrist fractures. Right. 00:52:45.670 --> 00:52:47.550 So ensuring these patients receive appropriate 00:52:47.550 --> 00:52:50.130 follow -up, which usually involves bone density 00:52:50.130 --> 00:52:52.929 testing, like a decasis scan, and then management, 00:52:53.269 --> 00:52:56.260 which might include lifestyle advice, calcium 00:52:56.260 --> 00:52:58.559 and vitamin D supplementation, and potentially 00:52:58.559 --> 00:53:01.619 specific osteoporosis medications. That's a key 00:53:01.619 --> 00:53:04.699 part of providing comprehensive care. It's not 00:53:04.699 --> 00:53:06.820 just about fixing the immediate break. That connects 00:53:06.820 --> 00:53:08.820 back really powerfully to prevention then, doesn't 00:53:08.820 --> 00:53:11.619 it? If poor bone quality and falls are the major 00:53:11.619 --> 00:53:14.079 factors driving the most common type of proximal 00:53:14.079 --> 00:53:16.400 humerus fracture, then surely addressing those 00:53:16.400 --> 00:53:18.719 upstream issues has to be critical. Absolutely. 00:53:19.400 --> 00:53:22.199 And Unknown 19 provides some specific prevention 00:53:22.199 --> 00:53:24.400 strategies that resonate broadly with the idea 00:53:24.400 --> 00:53:27.199 of risk management. management. For older adults, 00:53:27.659 --> 00:53:29.659 fall prevention is paramount. What does that 00:53:29.659 --> 00:53:32.179 involve? It involves several things. Identifying 00:53:32.179 --> 00:53:34.280 and modifying potential environmental hazards 00:53:34.280 --> 00:53:37.179 in their home, things like securing loose rugs, 00:53:37.460 --> 00:53:40.239 improving lighting, installing grab bars or handrails 00:53:40.239 --> 00:53:43.139 in bathrooms and on stairs. It also involves 00:53:43.139 --> 00:53:45.800 reviewing their medications, as some can cause 00:53:45.800 --> 00:53:48.619 dizziness or unsteadiness. Ensuring they have 00:53:48.619 --> 00:53:50.699 appropriate, well -fitting footwear is important 00:53:50.699 --> 00:53:53.730 too. And crucially, incorporating regular balance 00:53:53.730 --> 00:53:56.010 and strength training exercises into their routine 00:53:56.010 --> 00:53:59.349 can significantly reduce fall risk. For athletes 00:53:59.349 --> 00:54:02.469 or perhaps people involved in high impact activities 00:54:02.469 --> 00:54:05.050 or contact sports, using appropriate protective 00:54:05.050 --> 00:54:07.409 gear like shoulder pads where relevant is key. 00:54:07.659 --> 00:54:10.199 And for everyone, really, particularly as we 00:54:10.199 --> 00:54:13.440 age, focusing on overall bone health is vital. 00:54:13.880 --> 00:54:16.699 That means ensuring adequate dietary intake or 00:54:16.699 --> 00:54:19.539 supplementation of calcium and vitamin D, avoiding 00:54:19.539 --> 00:54:22.519 smoking, limiting alcohol intake, and engaging 00:54:22.519 --> 00:54:24.519 in regular weight -bearing physical activity, 00:54:24.820 --> 00:54:27.199 things like walking, jogging, dancing, stair 00:54:27.199 --> 00:54:29.500 climbing, which helps stimulate bone density 00:54:29.500 --> 00:54:32.159 and also maintain muscle strength, which further 00:54:32.159 --> 00:54:34.730 supports balance and reduces fall risk. This 00:54:34.730 --> 00:54:36.789 entire journey we've discussed from, you know, 00:54:36.909 --> 00:54:39.130 really understanding the intricate anatomy of 00:54:39.130 --> 00:54:41.889 the brake and classifying its severity to then 00:54:41.889 --> 00:54:43.809 navigating those complex treatment decisions 00:54:43.809 --> 00:54:45.849 with all their inherent risks and trade -offs 00:54:45.849 --> 00:54:48.329 and then committing to what sounds like an often 00:54:48.329 --> 00:54:50.630 arduous road of recovery while managing potential 00:54:50.630 --> 00:54:53.250 complications, it truly does mirror challenges 00:54:53.250 --> 00:54:55.829 we often face in many professional domains, doesn't 00:54:55.829 --> 00:54:59.050 it? It really does. That need to deeply understand 00:54:59.050 --> 00:55:02.159 a complex system before intervening. the need 00:55:02.159 --> 00:55:05.260 to classify problems effectively to help guide 00:55:05.260 --> 00:55:08.019 action, the need to weigh different potential 00:55:08.019 --> 00:55:10.900 solutions based on evidence, but also considering 00:55:10.900 --> 00:55:13.260 the specific context and the individual system 00:55:13.260 --> 00:55:15.760 you're dealing with, the need to anticipate and 00:55:15.760 --> 00:55:18.719 manage inherent risks, and ultimately the need 00:55:18.719 --> 00:55:21.679 to embrace a resilient, often team -based approach 00:55:21.679 --> 00:55:24.179 to achieve the desired outcome. Whether you're 00:55:24.179 --> 00:55:26.280 talking about healthcare, engineering, finance, 00:55:26.360 --> 00:55:28.699 or business strategy, these core principles seem 00:55:28.699 --> 00:55:31.059 remarkably consistent. Well, we hope this deep 00:55:31.059 --> 00:55:33.360 dive has given you a much clearer picture of 00:55:33.360 --> 00:55:35.840 proximal humerus fractures, perhaps revealing 00:55:35.840 --> 00:55:37.800 some of the layers of complexity beneath what 00:55:37.800 --> 00:55:39.679 might initially seem like just a straightforward 00:55:39.679 --> 00:55:42.820 broken bone. Yes. From the subtle yet critical 00:55:42.820 --> 00:55:45.659 points of anatomy, the distinct patterns of injury 00:55:45.659 --> 00:55:48.880 depending on age and mechanism, the classification 00:55:48.880 --> 00:55:50.739 systems that help structure our decision -making 00:55:50.739 --> 00:55:53.519 around displacement, the important nuances and 00:55:53.519 --> 00:55:56.400 trade -offs between non -operative care and the 00:55:56.400 --> 00:55:58.699 various operative strategies, right through to 00:55:58.699 --> 00:56:01.179 the demanding but absolutely vital process of 00:56:01.179 --> 00:56:03.699 rehabilitation and being aware of the potential 00:56:03.699 --> 00:56:05.699 hurdles of complications, understanding these 00:56:05.699 --> 00:56:08.460 different facets really provides a robust framework 00:56:08.460 --> 00:56:10.639 for thinking about this injury. And it all stems 00:56:10.639 --> 00:56:13.300 directly from the comprehensive source material 00:56:13.300 --> 00:56:15.559 we've been exploring today, the Orthopedic Trauma 00:56:15.559 --> 00:56:18.300 Association guidelines, those detailed reviews 00:56:18.300 --> 00:56:20.880 and stat pearls and ortho bullets, insights from 00:56:20.880 --> 00:56:24.079 the bone school and the Stanford AVA lab summary 00:56:24.079 --> 00:56:27.139 document. So our thanks to the experts and authors 00:56:27.139 --> 00:56:29.920 behind all of those valuable resources. Indeed. 00:56:30.539 --> 00:56:32.539 They provide the foundational knowledge that's 00:56:32.539 --> 00:56:34.840 absolutely necessary to navigate what is often 00:56:34.840 --> 00:56:37.559 a very complex clinical challenge. If you found 00:56:37.559 --> 00:56:39.860 this deep dive insightful, perhaps because it 00:56:39.860 --> 00:56:41.980 helped you understand complexity through a slightly 00:56:41.980 --> 00:56:44.539 different lens today, please do consider leaving 00:56:44.539 --> 00:56:46.800 us a rating and maybe sharing it with someone 00:56:46.800 --> 00:56:48.780 in your network who you think might also benefit. 00:56:49.039 --> 00:56:51.480 And finally, perhaps consider this provocative 00:56:51.480 --> 00:56:53.719 thought. building on that increasing prevalence 00:56:53.719 --> 00:56:56.619 of these injuries, especially in older adults. 00:56:57.440 --> 00:56:59.980 Given the clear interception of an aging global 00:56:59.980 --> 00:57:03.139 population, the rising incidence of osteoporosis, 00:57:03.480 --> 00:57:05.960 and the significant functional implications in 00:57:05.960 --> 00:57:08.340 healthcare costs associated with proximal humerus 00:57:08.340 --> 00:57:10.820 fractures is the healthcare system currently 00:57:10.820 --> 00:57:14.019 doing enough to shift its focus from primarily 00:57:14.019 --> 00:57:16.280 treating these injuries after they happen to 00:57:16.280 --> 00:57:18.780 more effectively preventing them on a true population 00:57:18.780 --> 00:57:21.559 scale. What systemic changes might be needed 00:57:21.559 --> 00:57:24.300 to really manage this growing fragility fracture 00:57:24.300 --> 00:57:27.400 epidemic proactively rather than reactively? 00:57:27.820 --> 00:57:29.579 A question with some very broad implications 00:57:29.579 --> 00:57:31.860 indeed. Something to think about. Until next 00:57:31.860 --> 00:57:32.940 time on The Deep Dive.
