WEBVTT 00:00:00.000 --> 00:00:02.319 Welcome to The Deep Dive, the show where we cut 00:00:02.319 --> 00:00:05.160 through the noise, unpack complex medical topics, 00:00:05.219 --> 00:00:07.679 and pull out the crucial insights that can genuinely 00:00:07.679 --> 00:00:10.099 elevate your clinical practice. Today, we're 00:00:10.099 --> 00:00:11.880 plunging into a subject that, well, at first 00:00:11.880 --> 00:00:14.460 glance, seems incredibly straightforward, yet 00:00:14.460 --> 00:00:16.800 it consistently throws up significant challenges 00:00:16.800 --> 00:00:19.399 in diagnosis, treatment, and especially long 00:00:19.399 --> 00:00:22.960 -term patient recovery, ankle sprains. Now, when 00:00:22.960 --> 00:00:24.980 we talk about how common these are, the figures 00:00:24.980 --> 00:00:27.179 are really quite startling. We're looking at 00:00:27.179 --> 00:00:30.100 an estimated 28 ,000 ankle sprains happening 00:00:30.100 --> 00:00:32.880 every single day in the United States alone. 00:00:35.200 --> 00:00:37.560 It really is. And if you've spent any time in 00:00:37.560 --> 00:00:40.259 sports medicine or even A &E, you'll know it's 00:00:40.259 --> 00:00:42.240 often the single biggest reason why athletes 00:00:42.240 --> 00:00:45.240 miss participation. So despite their ubiquity, 00:00:45.380 --> 00:00:47.659 their impact, both on individuals and on health 00:00:47.659 --> 00:00:51.240 care systems, is undeniably profound. Our mission 00:00:51.240 --> 00:00:54.219 today is to unpack the intricate nuances of these 00:00:54.219 --> 00:00:56.880 injuries, from the fundamental anatomy that underpins 00:00:56.880 --> 00:00:59.759 them to the cutting edge advanced treatment protocols 00:00:59.759 --> 00:01:02.820 and, crucially, the prevention strategies that 00:01:02.820 --> 00:01:05.670 can make all the difference. We want to provide 00:01:05.670 --> 00:01:08.049 you, our discerning medical professional listener, 00:01:08.209 --> 00:01:10.790 with a comprehensive yet concise understanding 00:01:10.790 --> 00:01:13.549 that you can apply directly. And to guide us 00:01:13.549 --> 00:01:15.769 through this intricate landscape, I'm absolutely 00:01:15.769 --> 00:01:18.290 thrilled to welcome Prof. Mal Imam. Thank you 00:01:18.290 --> 00:01:19.930 so much for having me. It's a genuine pleasure. 00:01:20.129 --> 00:01:21.810 You've really nailed the core issue right there. 00:01:22.329 --> 00:01:24.650 Ankle sprains are indeed incredibly common, almost 00:01:24.650 --> 00:01:26.530 a rite of passage for many active individuals, 00:01:26.609 --> 00:01:28.109 aren't they? Almost seems that way sometimes. 00:01:28.370 --> 00:01:30.879 But the critical point... And one that's so often 00:01:30.879 --> 00:01:33.579 underestimated is their potential for serious 00:01:33.579 --> 00:01:36.700 debilitating long -term complications if they're 00:01:36.700 --> 00:01:40.359 not managed appropriately from day one. We frequently 00:01:40.359 --> 00:01:42.900 see patients in clinic years down the line still 00:01:42.900 --> 00:01:45.299 grappling with persistent pain, instability, 00:01:45.459 --> 00:01:48.159 or even early arthritis, all stemming from an 00:01:48.159 --> 00:01:50.500 initial sprain that simply wasn't given the attention 00:01:50.500 --> 00:01:53.260 it deserved. So that initial management is key. 00:01:53.540 --> 00:01:55.840 Absolutely critical. For this deep dive, we're 00:01:55.840 --> 00:01:58.159 going to embark on a comprehensive journey, starting 00:01:58.159 --> 00:02:00.840 with the very first moment of injury, understanding 00:02:00.840 --> 00:02:03.459 the mechanisms, then moving through precise diagnostic 00:02:03.459 --> 00:02:05.959 approaches, exploring the full spectrum of treatment 00:02:05.959 --> 00:02:08.180 from conservative to operative, and finally, 00:02:08.500 --> 00:02:10.659 really honing in on robust prevention strategies. 00:02:11.419 --> 00:02:13.840 Our shared aim is to arm you with actionable, 00:02:14.219 --> 00:02:16.400 evidence -based insights that can significantly 00:02:16.400 --> 00:02:19.460 improve patient outcomes. Right then. Let's roll 00:02:19.460 --> 00:02:21.759 up our sleeves and get into it. Before we even 00:02:21.759 --> 00:02:24.580 begin to unpick the various types of ankle injuries 00:02:24.580 --> 00:02:27.099 and their manifestations, could you perhaps take 00:02:27.099 --> 00:02:30.360 us back to basics? For many of us, it's, well, 00:02:30.500 --> 00:02:32.639 it's been a while since anatomy lab. Could you 00:02:32.639 --> 00:02:35.259 refresh our memory on the critical structural 00:02:35.259 --> 00:02:38.460 foundations of the ankle? Specifically, which 00:02:38.460 --> 00:02:41.539 ligaments are the prime suspects, the most vulnerable 00:02:41.539 --> 00:02:44.759 players in a typical ankle sprain scenario? Absolutely. 00:02:45.039 --> 00:02:47.099 Happy to. It's always vital to start with the 00:02:47.099 --> 00:02:49.599 foundations, as understanding the anatomy illuminates 00:02:49.599 --> 00:02:53.460 the pathology. The ankle joint itself is a marvel 00:02:53.460 --> 00:02:56.479 of engineering, really. A complex articulation 00:02:56.479 --> 00:02:59.340 involving three primary bones, the tibia and 00:02:59.340 --> 00:03:01.180 fibula, which are the long bones of your lower 00:03:01.180 --> 00:03:03.879 leg, and the talus, the crucial bone in your 00:03:03.879 --> 00:03:06.259 foot, that essentially acts as the fulcrum between 00:03:06.259 --> 00:03:07.939 your leg and the rest of your foot. The connecting 00:03:07.939 --> 00:03:11.139 piece. Precisely. These three bones are held 00:03:11.139 --> 00:03:14.240 together quite ingeniously by a sophisticated 00:03:14.240 --> 00:03:17.080 network of robust ligaments. These aren't just 00:03:17.080 --> 00:03:19.900 passive restraints. They provide both the necessary 00:03:19.900 --> 00:03:22.900 static stability and also guide the intricate 00:03:22.900 --> 00:03:24.939 range of motion required for everything from 00:03:24.939 --> 00:03:28.240 a gentle stroll to a full -on sprint. When we 00:03:28.240 --> 00:03:30.400 talk about ankle sprains, we're almost exclusively 00:03:30.400 --> 00:03:33.060 referring to injuries to these ligaments. And 00:03:33.060 --> 00:03:35.139 we can broadly categorize them into two main 00:03:35.139 --> 00:03:37.580 groups based on their location and the type of 00:03:37.580 --> 00:03:40.370 force they resist. On the outer side of the ankle, 00:03:40.530 --> 00:03:42.469 the lateral aspect, we find the ligaments that 00:03:42.469 --> 00:03:45.270 are unfortunately the most frequent victims in 00:03:45.270 --> 00:03:48.370 ankle sprains. The absolute lead character here, 00:03:48.490 --> 00:03:50.810 if you will, but one that gets injured most commonly, 00:03:51.250 --> 00:03:54.030 is the anterior telofibular ligament, or ATFL. 00:03:54.229 --> 00:03:56.169 ATFL, okay. This ligament is quite slender and 00:03:56.169 --> 00:03:58.530 is positioned anteriorly at the front, connecting 00:03:58.530 --> 00:04:01.219 the fibula to the talus. It's typically injured 00:04:01.219 --> 00:04:03.639 when the foot is in a planter flexed or pointed 00:04:03.639 --> 00:04:06.780 down position and then rolls inwards that classic 00:04:06.780 --> 00:04:08.900 inversion mechanism like stepping awkwardly off 00:04:08.900 --> 00:04:11.419 a curb or landing badly from a jump. The classic 00:04:11.419 --> 00:04:14.099 going over on your ankle. Exactly that. It's 00:04:14.099 --> 00:04:16.240 the weakest of the lateral ligaments, which is 00:04:16.240 --> 00:04:19.079 why it bears the brunt of most inversion injuries. 00:04:20.120 --> 00:04:22.379 Following the ATFL in terms of injury frequency 00:04:22.379 --> 00:04:26.009 is the calcaneofibular ligament. or CFL. This 00:04:26.009 --> 00:04:28.389 one sits a bit deeper and more vertically, connecting 00:04:28.389 --> 00:04:31.089 the fibula to the calcaneus, your heel bone. 00:04:31.529 --> 00:04:34.389 So fibula to heel bone? Correct. It tends to 00:04:34.389 --> 00:04:36.569 be affected when the foot is in a more neutral 00:04:36.569 --> 00:04:39.949 or even dorsiflex, flexed upwards position, during 00:04:39.949 --> 00:04:42.889 an inversion injury. A critical distinction with 00:04:42.889 --> 00:04:46.009 the CFL is its role not just in ankle joint stability, 00:04:46.310 --> 00:04:48.629 but also in supporting the subtailer joint, which 00:04:48.629 --> 00:04:50.829 allows for inversion and eversion of the foot. 00:04:51.009 --> 00:04:52.930 Ah, so it affects more than just the main ankle 00:04:52.930 --> 00:04:56.180 hinge. Indeed. An injury to the CFL can have 00:04:56.180 --> 00:04:58.779 broader implications for foot mechanics. And 00:04:58.779 --> 00:05:01.079 then, less commonly involved, usually only in 00:05:01.079 --> 00:05:03.139 quite severe or multi -ligamentous injuries, 00:05:03.600 --> 00:05:06.939 is the posterior televibular ligament, or PTFL, 00:05:06.939 --> 00:05:08.980 which, as its name suggests, is at the back. 00:05:09.480 --> 00:05:11.300 Now, shifting our focus to the inner side of 00:05:11.300 --> 00:05:13.680 the ankle, the medial aspect, we encounter the 00:05:13.680 --> 00:05:15.819 exceptionally strong deltoid latiment. The medial 00:05:15.819 --> 00:05:19.319 side, right? Yes. This isn't a single band, but 00:05:19.319 --> 00:05:22.579 rather a broad, fan -shaped complex made up of 00:05:22.579 --> 00:05:26.129 several distinct parts. It provides truly substantial 00:05:26.129 --> 00:05:28.750 support to the inner ankle and plays a crucial 00:05:28.750 --> 00:05:31.850 role in limiting talar abduction. It's the outward 00:05:31.850 --> 00:05:34.670 movement of the talus. Okay. And its deep portion 00:05:34.670 --> 00:05:37.449 is particularly good at limiting external rotation 00:05:37.449 --> 00:05:40.930 of the talus. Essentially, it's the primary guardian 00:05:40.930 --> 00:05:43.470 against excessive aversion of the foot, where 00:05:43.470 --> 00:05:46.389 the ankle rolls outwards. So it stops the ankle 00:05:46.389 --> 00:05:48.730 collapsing inwards effectively. Precisely. It 00:05:48.730 --> 00:05:51.769 resists that outward roll, the aversion. Interestingly, 00:05:52.089 --> 00:05:54.920 because of its inherent strength and broad attachment, 00:05:55.720 --> 00:05:57.800 isolated injuries to the deltoid ligament are 00:05:57.800 --> 00:05:59.620 relatively rare. You don't see them often on 00:05:59.620 --> 00:06:02.079 their own. Not usually. When they do occur, they 00:06:02.079 --> 00:06:04.660 often signify a higher energy trauma or occur 00:06:04.660 --> 00:06:06.379 in conjunction with other injuries, sometimes 00:06:06.379 --> 00:06:08.740 even a fracture, because the bone gives way before 00:06:08.740 --> 00:06:10.399 the ligament does. Right, the forces must be 00:06:10.399 --> 00:06:13.519 significant. They usually are. So understanding 00:06:13.519 --> 00:06:16.019 these specific anatomical relationships, knowing 00:06:16.019 --> 00:06:19.100 exactly which ligament sits where and how it 00:06:19.100 --> 00:06:22.000 functions to provide stability is absolutely 00:06:22.000 --> 00:06:24.199 paramount. It's what allows us to accurately 00:06:24.199 --> 00:06:26.879 diagnose the mechanism of injury when a patient 00:06:26.879 --> 00:06:29.199 walks into our clinic. That's a truly excellent 00:06:29.199 --> 00:06:31.279 anatomical breakdown, Prof. It really paints 00:06:31.279 --> 00:06:33.560 a clear picture and sets the stage for understanding 00:06:33.560 --> 00:06:35.959 the injury itself. So with that intricate anatomy 00:06:35.959 --> 00:06:38.699 now firmly in our minds, let's move on to the 00:06:38.699 --> 00:06:41.569 practical reality. What are the primary types 00:06:41.569 --> 00:06:43.970 of ankle sprains we commonly encounter in clinical 00:06:43.970 --> 00:06:46.470 practice, and how do their underlying mechanisms 00:06:46.470 --> 00:06:48.990 and defining characteristics truly differ? I 00:06:48.990 --> 00:06:51.629 mean, it's not just a twisted ankle, is it? Precisely. 00:06:52.089 --> 00:06:54.310 It's far more nuanced than just a twisted ankle. 00:06:55.470 --> 00:06:58.050 For clinicians, classifying these injuries is 00:06:58.050 --> 00:07:01.050 fundamental to effective management. We primarily 00:07:01.050 --> 00:07:03.329 categorize ankle sprains based on the direction 00:07:03.329 --> 00:07:05.810 the foot moves during the injury, which in turn 00:07:05.810 --> 00:07:07.829 dictates which ligaments bear the brunt of the 00:07:07.829 --> 00:07:10.490 force. There are essentially three main types 00:07:10.490 --> 00:07:13.250 we encounter. First, and by far the most ubiquitous, 00:07:13.470 --> 00:07:16.110 are inversion sprains. These are what many colloquially 00:07:16.110 --> 00:07:18.930 refer to as low ankle sprains, and they represent 00:07:18.930 --> 00:07:21.970 over 90 % of all ankle sprains we see. Over 90 00:07:21.970 --> 00:07:25.290 %? Easily. The mechanism is exactly as it sounds. 00:07:25.709 --> 00:07:27.910 The foot rolls inward, often quite violently, 00:07:28.310 --> 00:07:29.829 leading to damage of those lateral ligaments 00:07:29.829 --> 00:07:32.389 we just discussed, predominantly the ATFL and 00:07:32.389 --> 00:07:34.870 frequently the CFL as well, especially if the 00:07:34.870 --> 00:07:36.870 injury is more severe. So the outer ligaments? 00:07:37.079 --> 00:07:41.360 Yes, the classic scenario is an inversion injury 00:07:41.360 --> 00:07:44.540 on a plantar flexed foot. Think of stepping into 00:07:44.540 --> 00:07:47.100 a pothole, landing awkwardly after a jump in 00:07:47.100 --> 00:07:50.180 netball, or simply misjudging a step off a curb. 00:07:50.920 --> 00:07:53.519 The forces here can be quite significant, often 00:07:53.519 --> 00:07:55.819 leading to immediate pain and swelling on the 00:07:55.819 --> 00:07:59.339 outer side of the ankle. Secondly, we have aversion 00:07:59.339 --> 00:08:02.279 sprains. These are significantly less common, 00:08:02.459 --> 00:08:04.879 and for good reason. As we just highlighted, 00:08:05.180 --> 00:08:07.000 the deltoid ligament on the inner side of the 00:08:07.000 --> 00:08:09.120 ankle is exceptionally robust. A big fan -shaped 00:08:09.120 --> 00:08:11.300 one. Exactly. An aversion sprain occurs when 00:08:11.300 --> 00:08:13.560 the ankle rolls outward, placing immense stress 00:08:13.560 --> 00:08:16.759 on this formidable deltoid ligament. These types 00:08:16.759 --> 00:08:19.399 of sprains typically demand a much more forceful 00:08:19.399 --> 00:08:22.120 external rotation or abduction mechanism, often 00:08:22.120 --> 00:08:24.720 involving a higher energy impact, such as a contact 00:08:24.720 --> 00:08:27.629 sports injury or a motor vehicle accident. Because 00:08:27.629 --> 00:08:30.449 the deltoid is so strong, an isolated aversion 00:08:30.449 --> 00:08:32.809 sprain is rare. You're often looking for an associated 00:08:32.809 --> 00:08:35.289 fracture, perhaps of the fibula, because the 00:08:35.289 --> 00:08:36.889 bone might break before the ligament pair. Interesting. 00:08:37.049 --> 00:08:40.009 And thirdly, a less common but often far more 00:08:40.009 --> 00:08:42.950 debilitating and challenging type are syndesmotic 00:08:42.950 --> 00:08:46.549 sprains, universally known as high ankle sprains. 00:08:46.710 --> 00:08:49.759 The dreaded high ankle sprain. Indeed. While 00:08:49.759 --> 00:08:52.799 they only account for about 1 % to 10 % of all 00:08:52.799 --> 00:08:56.159 ankle sprains, their significance is disproportionately 00:08:56.159 --> 00:08:59.240 high. These injuries involve the tibiofibular 00:08:59.240 --> 00:09:02.299 ligaments, specifically the anterior and posterior 00:09:02.299 --> 00:09:05.019 tibiofibular ligaments, and the interosseous 00:09:05.019 --> 00:09:07.259 membrane, which connect the tibia and fibula 00:09:07.259 --> 00:09:09.580 bones above the actual ankle joint. Right, higher 00:09:09.580 --> 00:09:12.279 up the leg. Correct. They're critical for maintaining 00:09:12.279 --> 00:09:14.460 the integrity of the tibiofibular syndesmosis, 00:09:14.659 --> 00:09:17.200 which forms the roof of the ankle mortis. These 00:09:17.200 --> 00:09:19.220 sprains are frequently associated with high -end 00:09:19.220 --> 00:09:21.799 impact activities and powerful twisting motions, 00:09:22.340 --> 00:09:23.879 particularly where there's external rotation 00:09:23.879 --> 00:09:27.279 of the foot on a fixed or planted leg or hyperdorsiflexion. 00:09:27.440 --> 00:09:30.740 Like in rugby or football tackles. Exactly those 00:09:30.740 --> 00:09:33.159 sorts of scenarios. Think of a rugby player getting 00:09:33.159 --> 00:09:35.639 tackled with their foot caught or a footballer 00:09:35.639 --> 00:09:38.659 twisting on the pitch. The key takeaway here 00:09:38.659 --> 00:09:41.340 is that syndesmotic injuries can lead to significant 00:09:41.340 --> 00:09:44.340 and chronic instability if not correctly identified 00:09:44.340 --> 00:09:47.639 and managed, and they invariably demand a much, 00:09:47.639 --> 00:09:50.559 much longer recovery period compared to the more 00:09:50.559 --> 00:09:52.720 common lateral sprains. Much longer recovery, 00:09:52.759 --> 00:09:55.559 okay. Significantly longer. Yeah. Beyond this 00:09:55.559 --> 00:09:58.460 specific mechanism, we then classify ankle sprains 00:09:58.460 --> 00:10:01.559 by their severity, which naturally directly dictates 00:10:01.559 --> 00:10:04.240 the immediate management plan and the prognostic 00:10:04.240 --> 00:10:07.580 outlook. This uses a widely accepted three -grade 00:10:07.580 --> 00:10:10.200 system, and it's essential for clinical decision 00:10:10.200 --> 00:10:12.980 -making. Great ice brains represent the mildest 00:10:12.980 --> 00:10:15.259 form. Here, there's just a slight stretching 00:10:15.259 --> 00:10:17.860 of the ligament fibers, perhaps with some microscopic 00:10:17.860 --> 00:10:20.279 tears. Clinically, you'll observe minimal pain, 00:10:20.559 --> 00:10:22.799 often a bit of mild swelling, and perhaps very 00:10:22.799 --> 00:10:25.700 slight localized ecomosis or bruising. So, quite 00:10:25.700 --> 00:10:28.740 subtle sometimes. Can be. Crucially, the patient 00:10:28.740 --> 00:10:31.500 can usually bear weight normally. albeit perhaps 00:10:31.500 --> 00:10:34.200 with some discomfort, and there's no detectable 00:10:34.200 --> 00:10:36.559 ligamentous instability during your physical 00:10:36.559 --> 00:10:39.320 examination. They might feel a bit stiff, but 00:10:39.320 --> 00:10:42.519 the joint itself feels solid. Grade 2 sprains 00:10:42.519 --> 00:10:45.580 indicate a more significant injury, a partial 00:10:45.580 --> 00:10:48.080 tearing of the ligament. At this grade, the pain 00:10:48.080 --> 00:10:50.759 is moderate, and you'll typically see more noticeable 00:10:50.759 --> 00:10:53.159 swelling and bruising. Patients will experience 00:10:53.159 --> 00:10:55.580 mild to moderate pain with weight bearing, and 00:10:55.580 --> 00:10:58.200 during your examination, you might detect slight, 00:10:58.440 --> 00:11:01.120 but definite instability. A bit wobbly. A bit 00:11:01.120 --> 00:11:03.759 wobbly, yes. A classic, though not universal, 00:11:04.320 --> 00:11:06.659 presentation for grade 2 sprains is often characteristic 00:11:06.659 --> 00:11:08.620 horseshoe -shaped bruise that appears around 00:11:08.620 --> 00:11:10.559 the heel. Ah, yes, I've seen that. Sort of wraps 00:11:10.559 --> 00:11:13.779 around the malleolus. Exactly. That pattern is 00:11:13.779 --> 00:11:15.919 quite indicative of the extent of the soft tissue 00:11:15.919 --> 00:11:19.259 damage and the underlying hematoma. Finally, 00:11:19.580 --> 00:11:22.320 grade 3 sprains represent the most severe injury, 00:11:22.960 --> 00:11:25.039 a complete rupture of one or more ligaments. 00:11:25.389 --> 00:11:27.769 These are truly painful injuries, presenting 00:11:27.769 --> 00:11:31.669 with pronounced, often excruciating, pain, significant 00:11:31.669 --> 00:11:34.269 and rapid swelling, extensive ecomosis that can 00:11:34.269 --> 00:11:36.690 spread quite widely, and sometimes even a visible 00:11:36.690 --> 00:11:38.789 deformity of the ankle due to the swelling and 00:11:38.789 --> 00:11:41.009 instability. Can't bear weight at all, usually. 00:11:41.230 --> 00:11:44.490 Often impossible or severely painful. And during 00:11:44.490 --> 00:11:46.590 your examination, you will detect substantial 00:11:46.590 --> 00:11:49.379 instability of the joint. It's this grade in 00:11:49.379 --> 00:11:51.899 particular where meticulous and careful management 00:11:51.899 --> 00:11:54.919 is absolutely critical to prevent the transition 00:11:54.919 --> 00:11:57.919 to long -term chronic instability and other complications 00:11:57.919 --> 00:11:59.960 we'll discuss later. Makes sense. Understanding 00:11:59.960 --> 00:12:02.240 these grades is truly fundamental for any clinician 00:12:02.240 --> 00:12:04.860 as it directly guides your immediate therapeutic 00:12:04.860 --> 00:12:07.779 approach and helps in setting realistic expectations 00:12:07.779 --> 00:12:10.419 for the patient's recovery trajectory. That distinction 00:12:10.419 --> 00:12:12.740 between the specific mechanisms and then the 00:12:12.740 --> 00:12:15.580 subsequent severity grading is incredibly helpful 00:12:15.580 --> 00:12:18.320 for navigating what patients present with. It 00:12:18.320 --> 00:12:21.220 transforms a vague twisted ankle into a precise 00:12:21.220 --> 00:12:24.259 diagnosis. Now, let's pivot and consider the 00:12:24.259 --> 00:12:27.100 why behind these injuries. What are the typical 00:12:27.100 --> 00:12:29.799 scenarios that often lead to ankle sprains, and 00:12:29.799 --> 00:12:32.340 what should we as clinicians be acutely aware 00:12:32.340 --> 00:12:34.600 of regarding both intrinsic patient -related 00:12:34.600 --> 00:12:37.360 factors and extrinsic environmental risk factors? 00:12:37.899 --> 00:12:40.820 What makes someone more vulnerable? It's a fantastic 00:12:40.820 --> 00:12:43.440 question because understanding the etiology is 00:12:43.440 --> 00:12:45.559 paramount, not just for acute management, but 00:12:45.559 --> 00:12:48.350 crucially for prevention. The primary cause of 00:12:48.350 --> 00:12:51.149 an ankle sprain is almost always a sudden, uncontrolled, 00:12:51.330 --> 00:12:53.590 and forceful twisting motion of the foot or ankle. 00:12:53.750 --> 00:12:56.070 Right. This can manifest in a myriad of common 00:12:56.070 --> 00:12:59.009 scenarios. Think of simply misstepping on uneven 00:12:59.009 --> 00:13:01.710 terrain, that unexpected dip in a pavement, or 00:13:01.710 --> 00:13:04.169 a rogue tree root on a trail run. Tripping or 00:13:04.169 --> 00:13:06.129 falling is another ubiquitous cause, where the 00:13:06.129 --> 00:13:08.470 foot can unexpectedly roll inward or outward 00:13:08.470 --> 00:13:10.990 upon impact, or as you lose balance. Happens 00:13:10.990 --> 00:13:14.090 to everyone. It really does. However, a very 00:13:14.090 --> 00:13:16.700 significant proportion of ankle sprains especially 00:13:16.700 --> 00:13:19.460 the more severe ones, occur during sports and 00:13:19.460 --> 00:13:22.679 high impact activities. Any sport that demands 00:13:22.679 --> 00:13:25.580 sudden directional changes, rapid pivoting, quick 00:13:25.580 --> 00:13:28.419 cuts, or repetitive jumping, is inherently high 00:13:28.419 --> 00:13:30.860 risk. We're talking about basketball, volleyball, 00:13:31.259 --> 00:13:34.200 tennis, football, rugby, netball, essentially 00:13:34.200 --> 00:13:36.460 any dynamic sport where the foot can get caught 00:13:36.460 --> 00:13:38.899 or twisted while the body continues its motion. 00:13:39.120 --> 00:13:41.340 Landing awkwardly from a jump, perhaps? Very 00:13:41.340 --> 00:13:43.620 common mechanism. In the more severe cases of 00:13:43.620 --> 00:13:45.460 ligament tearing, patients will often vividly 00:13:45.460 --> 00:13:48.399 report hearing or feeling a distinct pop or snap 00:13:48.399 --> 00:13:51.580 at the very moment of injury. Ah, the pop always 00:13:51.580 --> 00:13:53.759 makes your ears prick up. It certainly should. 00:13:54.360 --> 00:13:57.039 This auditory sensory feedback is a strong indicator 00:13:57.039 --> 00:13:59.580 of a significant ligamentous event, often a complete 00:13:59.580 --> 00:14:02.059 rupture, and should immediately raise your index 00:14:02.059 --> 00:14:05.029 of suspicion during history taking. Beyond these 00:14:05.029 --> 00:14:07.350 direct causes, we also identify a number of key 00:14:07.350 --> 00:14:09.809 risk factors that predispose individuals to ankle 00:14:09.809 --> 00:14:12.429 sprains or to recurrent sprains. These are broadly 00:14:12.429 --> 00:14:14.669 categorized into patient -related or intrinsic 00:14:14.669 --> 00:14:17.350 factors and environmental -related or extrinsic 00:14:17.350 --> 00:14:20.509 factors. Okay, intrinsic first. Yes. On the intrinsic 00:14:20.509 --> 00:14:22.789 side, we frequently observe individuals with 00:14:22.789 --> 00:14:25.970 preexisting biomechanical limitations. For example, 00:14:26.330 --> 00:14:28.909 limited dorsiflexion. That's a restricted upward 00:14:28.909 --> 00:14:31.190 movement of the foot towards the shin. Skiffness 00:14:31.190 --> 00:14:34.649 going upwards. Exactly. It significantly increases 00:14:34.649 --> 00:14:37.590 risk because it limits the anchor's ability to 00:14:37.590 --> 00:14:41.610 absorb shock and adapt to uneven surfaces. Similarly, 00:14:42.470 --> 00:14:45.509 decreased proprioception. The body's subconscious 00:14:45.509 --> 00:14:48.070 awareness of its position in space and a general 00:14:48.070 --> 00:14:50.789 balance deficiency are major contributors. So 00:14:50.789 --> 00:14:54.399 poor balance control. Precisely. If your body 00:14:54.399 --> 00:14:56.299 isn't getting accurate feedback on where your 00:14:56.299 --> 00:14:58.899 foot is in relation to the ground, or if your 00:14:58.899 --> 00:15:01.419 reflexive muscle responses are slow, you're far 00:15:01.419 --> 00:15:04.159 more likely to roll your ankle. Furthermore, 00:15:04.639 --> 00:15:07.320 a subtle cavivarous foot alignment, a foot structure 00:15:07.320 --> 00:15:09.759 characterized by a high arch and a heel that 00:15:09.759 --> 00:15:12.039 turns slightly inward. High arch is heel turned 00:15:12.039 --> 00:15:14.960 in. Yes. That can place the ankle in a persistently 00:15:14.960 --> 00:15:17.059 more vulnerable position for recurrent inversion 00:15:17.059 --> 00:15:19.779 injuries. This is a structural predisposition 00:15:19.779 --> 00:15:21.720 that puts the lateral ligaments under greater 00:15:21.720 --> 00:15:23.940 baseline tension. Making them more prone to injury. 00:15:24.320 --> 00:15:27.659 Inherently more prone. As for the extrinsic factors, 00:15:27.870 --> 00:15:30.029 Indoor court sports have historically presented 00:15:30.029 --> 00:15:32.870 the highest risk, primarily due to the combination 00:15:32.870 --> 00:15:35.850 of rapid multi -directional movements on often 00:15:35.850 --> 00:15:38.710 hard, unforgiving surfaces that offer high friction, 00:15:39.330 --> 00:15:40.950 sometimes causing the foot to stick while the 00:15:40.950 --> 00:15:43.690 body rotates. Like basketball or netball court. 00:15:43.970 --> 00:15:47.450 Exactly. Recognizing these modifiable risk factors 00:15:47.450 --> 00:15:50.159 is absolutely paramount. It's not just about 00:15:50.159 --> 00:15:52.620 treating the acute injury, it's about implementing 00:15:52.620 --> 00:15:55.720 effective long -term prevention strategies, particularly 00:15:55.720 --> 00:15:58.679 within athletic populations, to break that cycle 00:15:58.679 --> 00:16:01.320 of recurrent sprains. It's fascinating how those 00:16:01.320 --> 00:16:03.840 subtle biomechanical environmental factors can 00:16:03.840 --> 00:16:06.500 contribute to such a common injury. Now, when 00:16:06.500 --> 00:16:08.539 a patient actually walks into our clinic with 00:16:08.539 --> 00:16:10.750 a suspected ankle sprain, often in quite a bit 00:16:10.750 --> 00:16:13.470 of pain and distress, what are the absolute key 00:16:13.470 --> 00:16:16.029 symptoms we should be looking out for? And crucially, 00:16:16.190 --> 00:16:18.090 what are the essential elements of our clinical 00:16:18.090 --> 00:16:20.250 and imaging evaluations to ensure we arrive at 00:16:20.250 --> 00:16:23.049 an accurate diagnosis and, perhaps even more 00:16:23.049 --> 00:16:25.350 importantly, rule out anything more sinister, 00:16:25.450 --> 00:16:28.389 like a fracture or a more complex injury? This 00:16:28.389 --> 00:16:30.309 is truly where our clinical judgment shines, 00:16:30.450 --> 00:16:32.990 isn't it? When a patient presents, the symptoms 00:16:32.990 --> 00:16:34.950 they report will naturally guide your initial 00:16:34.950 --> 00:16:37.830 assessment. The most prevalent symptoms include 00:16:37.830 --> 00:16:40.480 acute pain, which can range from a dull ache 00:16:40.480 --> 00:16:43.860 to a sharp incapacitating pain, present at rest, 00:16:44.379 --> 00:16:47.019 exacerbated with weight -bearing, or during any 00:16:47.019 --> 00:16:49.139 movement of the ankle. Pain is obviously number 00:16:49.139 --> 00:16:52.059 one. Almost always. You'll almost invariably 00:16:52.059 --> 00:16:54.539 observe varying degrees of swelling and ecomosis 00:16:54.539 --> 00:16:57.539 or bruising around the affected area. This can 00:16:57.539 --> 00:17:00.179 be anything from mild puffiness to extensive 00:17:00.179 --> 00:17:03.200 disfiguring bruising that spreads widely across 00:17:03.200 --> 00:17:06.230 the foot and ankle. A very strong diagnostic 00:17:06.230 --> 00:17:09.029 indicator is tenderness to touch, specifically 00:17:09.029 --> 00:17:12.329 localized over the involved ligaments. This pinpoint 00:17:12.329 --> 00:17:14.869 tenderness directly over the ATFL or CFL, for 00:17:14.869 --> 00:17:17.230 example, is highly suggestive of their involvement. 00:17:17.289 --> 00:17:20.150 Finding that exact spot. Yes, it's very helpful. 00:17:20.509 --> 00:17:22.369 Patients will often describe a feeling of ankle 00:17:22.369 --> 00:17:24.549 instability or a sensation of the ankle giving 00:17:24.549 --> 00:17:26.950 way, particularly during movement or weight -bearing 00:17:26.950 --> 00:17:30.089 activities, even if it's a subtle feeling. Restricted 00:17:30.089 --> 00:17:31.990 range of motion is also extremely common due 00:17:31.990 --> 00:17:34.470 to pain, swelling, and muscle guarding. They 00:17:34.470 --> 00:17:37.329 just don't want to move it. Understandably. Less 00:17:37.329 --> 00:17:40.289 commonly, but important to note, some individuals 00:17:40.289 --> 00:17:42.730 might report numbness or tingling sensations 00:17:42.730 --> 00:17:45.049 in the foot or ankle, which warns consideration 00:17:45.049 --> 00:17:47.670 of nerve involvement. Great flag there. Potentially, 00:17:47.869 --> 00:17:51.470 yes. Needs careful assessment. And for those 00:17:51.470 --> 00:17:53.470 with recurrence sprains, they might describe 00:17:53.470 --> 00:17:56.289 new or persistent catching or popping sensations, 00:17:56.509 --> 00:17:59.670 which can signal associated intraarticular pathology, 00:17:59.910 --> 00:18:03.049 perhaps a loose body or cartilage damage. Now, 00:18:03.180 --> 00:18:05.400 Moving on to the clinical evaluation itself. 00:18:05.960 --> 00:18:08.339 It begins, as always, with a meticulous history. 00:18:09.140 --> 00:18:11.059 Understanding the precise mechanism of injury 00:18:11.059 --> 00:18:13.640 is crucial, how exactly the foot twisted, the 00:18:13.640 --> 00:18:16.279 direction of force, the surface, any immediate 00:18:16.279 --> 00:18:18.680 sounds or sensations like that pop we discussed. 00:18:18.920 --> 00:18:20.960 Getting the story straight. Absolutely. This 00:18:20.960 --> 00:18:22.920 immediately helps you narrow down which ligaments 00:18:22.920 --> 00:18:24.859 might be affected and the potential severity. 00:18:25.380 --> 00:18:27.680 The physical examination, while potentially painful 00:18:27.680 --> 00:18:29.839 for the patient due to acute inflammation and 00:18:29.839 --> 00:18:33.880 swelling, is absolutely essential. First, Observation. 00:18:34.339 --> 00:18:36.380 Visually assess the injured ankle. Crucially 00:18:36.380 --> 00:18:38.460 compare it to the contralateral uninjured ankle. 00:18:38.700 --> 00:18:41.079 Always compare. Always. Look for the extent of 00:18:41.079 --> 00:18:43.960 swelling. The exact location and pattern of ecumosis. 00:18:44.319 --> 00:18:46.960 Is it the classic horseshoe bruise? Is it more 00:18:46.960 --> 00:18:51.539 diffuse? Then palpation. Gently but systematically 00:18:51.539 --> 00:18:54.710 palpate around the entire ankle. Pinpointing 00:18:54.710 --> 00:18:57.329 tenderness directly over specific injured ligaments 00:18:57.329 --> 00:19:00.650 like the ATFL just anterior to the lateral malleolus 00:19:00.650 --> 00:19:03.730 or the CFL inferior to it is a key diagnostic 00:19:03.730 --> 00:19:06.250 step. You're also palpating around the malleoli 00:19:06.250 --> 00:19:08.289 and the base of the fifth metatarsal and navicular 00:19:08.289 --> 00:19:11.049 bone to rule out bony tenderness. Checking those 00:19:11.049 --> 00:19:13.269 Ottawa rules points. Exactly. We'll come back 00:19:13.269 --> 00:19:16.180 to those. Next, range of motion testing. Gently 00:19:16.180 --> 00:19:18.460 assess both active and passive movement of the 00:19:18.460 --> 00:19:21.279 ankle in all planes. While this will often be 00:19:21.279 --> 00:19:23.460 limited by pain and swelling in the acute phase, 00:19:23.980 --> 00:19:25.759 it gives you a baseline for functional impairment. 00:19:26.359 --> 00:19:28.950 Next, range of motion testing. Finally, and critically, 00:19:29.269 --> 00:19:31.289 stability testing helps assess the integrity 00:19:31.289 --> 00:19:33.730 of the ligaments. The interior drawer test is 00:19:33.730 --> 00:19:36.109 performed to check for excessive anterior displacement 00:19:36.109 --> 00:19:38.849 of the talus relative to the tibia. It's often 00:19:38.849 --> 00:19:41.490 best tested with the foot in slight plantar flexion 00:19:41.490 --> 00:19:43.970 when assessing the ATFL and endorsiflexion for 00:19:43.970 --> 00:19:46.650 the CFL. Testing that forward glide. Correct. 00:19:47.170 --> 00:19:49.230 However, its usefulness can be somewhat limited 00:19:49.230 --> 00:19:51.109 in the acute setting due to patient pain and 00:19:51.109 --> 00:19:54.609 muscle guarding. The TALR tilt test evaluates 00:19:54.609 --> 00:19:57.150 excessive ankle inversion typically. A difference 00:19:57.150 --> 00:19:59.450 greater than 15 degrees compared to the uninjured 00:19:59.450 --> 00:20:02.069 side is considered significant. 15 degrees difference. 00:20:02.269 --> 00:20:05.009 Yes, that's the threshold often cited. It strongly 00:20:05.009 --> 00:20:08.789 indicates injury to both the ATFL and CFL. This 00:20:08.789 --> 00:20:10.829 test is particularly valuable for diagnosing 00:20:10.829 --> 00:20:13.789 CFL injury by directly assessing overall ankle 00:20:13.789 --> 00:20:16.880 instability in the coronal plane. Now, regarding 00:20:16.880 --> 00:20:20.059 imaging studies, radiographs or x -rays are almost 00:20:20.059 --> 00:20:23.059 always your first -line imaging modality. Their 00:20:23.059 --> 00:20:25.740 primary purpose is to rule out fractures, which 00:20:25.740 --> 00:20:27.759 can often present with symptoms very similar 00:20:27.759 --> 00:20:30.819 to severe sprains. Crucial first step. Absolutely. 00:20:31.200 --> 00:20:33.440 The indications for x -rays are brilliantly guided 00:20:33.440 --> 00:20:36.500 by the widely adopted Ottawa ankle rules. These 00:20:36.500 --> 00:20:39.119 rules are incredibly sensitive, boasting a sensitivity 00:20:39.119 --> 00:20:42.819 between 96 % and 99 % for ruling out clinically 00:20:42.819 --> 00:20:45.400 significant ankle fractures. Very sensitive indeed. 00:20:45.470 --> 00:20:47.349 meaning if the patient doesn't meet the criteria, 00:20:47.890 --> 00:20:50.049 you can generally confidently exclude a fracture 00:20:50.049 --> 00:20:52.910 without x -rays, thereby reducing unnecessary 00:20:52.910 --> 00:20:55.410 radiation exposure. You should order x -rays 00:20:55.410 --> 00:20:57.470 if the patient presents with an inability to 00:20:57.470 --> 00:20:59.490 bear weight both immediately after the injury 00:20:59.490 --> 00:21:02.250 and in the emergency department or clinic, or 00:21:02.250 --> 00:21:03.990 if there's point tenderness over the posterior 00:21:03.990 --> 00:21:07.589 edge or tip of either the medial or lateral malleolus, 00:21:07.809 --> 00:21:09.970 or tenderness of the base of the fifth metatarsal 00:21:09.970 --> 00:21:12.579 or the navicular bone. So weight -bearing ability 00:21:12.579 --> 00:21:14.960 and those specific bony points. Those are the 00:21:14.960 --> 00:21:18.420 key criteria. Standard views include AP, lateral, 00:21:18.559 --> 00:21:20.380 and mortis views, with weight -bearing views 00:21:20.380 --> 00:21:22.799 where possible to assess joint space integrity 00:21:22.799 --> 00:21:25.539 under load. For suspected high ankle sprains, 00:21:25.900 --> 00:21:28.220 stress x -rays can be particularly useful for 00:21:28.220 --> 00:21:30.619 diagnosing syndesmosis injury. Stress views for 00:21:30.619 --> 00:21:33.849 the high sprains. Yes. You're specifically looking 00:21:33.849 --> 00:21:36.890 for asymmetric widening of the mortis, specifically 00:21:36.890 --> 00:21:39.349 a medial clear space widening greater than 4 00:21:39.349 --> 00:21:42.490 millimeters, and a tibiofibular clear space widening 00:21:42.490 --> 00:21:45.190 of 6 millimeters or more. These measurements 00:21:45.190 --> 00:21:48.329 indicate a diastasis, or separation, of the tibia 00:21:48.329 --> 00:21:51.309 and fibula. Varus stress fuse can also be used 00:21:51.309 --> 00:21:54.529 to diagnose CFL injury by assessing for an increased 00:21:54.529 --> 00:21:58.069 talar tilt. MRI is generally not routinely needed 00:21:58.069 --> 00:21:59.890 for the initial diagnosis of a straightforward 00:21:59.890 --> 00:22:02.430 ankle sprain. However, you should definitely 00:22:02.430 --> 00:22:05.150 consider an MRI if pain and instability persist 00:22:05.150 --> 00:22:07.029 for six to eight weeks following the initial 00:22:07.029 --> 00:22:09.650 sprain, despite appropriate conservative management. 00:22:09.710 --> 00:22:11.890 If things aren't getting better. Exactly. Or 00:22:11.890 --> 00:22:14.329 if you strongly suspect associated injuries that 00:22:14.329 --> 00:22:17.339 plain x -rays can't visualize. It's an excellent 00:22:17.339 --> 00:22:19.519 modality for evaluating soft tissue structures 00:22:19.519 --> 00:22:21.859 like perineal tendon pathology problems with 00:22:21.859 --> 00:22:24.200 the tendons on the outer ankle, osteochondral 00:22:24.200 --> 00:22:26.400 lesions of the talus, which are areas of damaged 00:22:26.400 --> 00:22:29.660 cartilage and underlying bone, occult or hidden 00:22:29.660 --> 00:22:31.759 syndesmotic injuries that weren't clear on x 00:22:31.759 --> 00:22:34.940 -ray, anterior or anterolateral synovitis, which 00:22:34.940 --> 00:22:37.359 is inflammation of the joint lining, or anterior 00:22:37.359 --> 00:22:39.559 ankle impingement, where soft tissues get pinched 00:22:39.559 --> 00:22:42.299 in the front of the ankle. So MRI for the complications 00:22:42.299 --> 00:22:44.519 or persistent symptoms. That's the general rule. 00:22:44.829 --> 00:22:47.289 Lastly, quick word on referral considerations. 00:22:48.139 --> 00:22:50.359 Orthopedic referrals are warranted for specific 00:22:50.359 --> 00:22:53.119 situations. This includes any suspected fractures 00:22:53.119 --> 00:22:55.380 that aren't clearly benign or simple on x -ray, 00:22:55.980 --> 00:22:58.599 any signs of neurovascular compromised numbness, 00:22:58.920 --> 00:23:01.019 tingling, diminished pulses. Durgent referral 00:23:01.019 --> 00:23:03.660 for those. Absolutely. Suspected tendon ruptures, 00:23:03.900 --> 00:23:06.720 such as the Achilles or perennial tendons, symptoms 00:23:06.720 --> 00:23:09.079 that are disproportionate to the trauma observed, 00:23:09.440 --> 00:23:11.420 perhaps indicating a more complex underlying 00:23:11.420 --> 00:23:14.640 issue, or if there's persistent diagnostic uncertainty 00:23:14.640 --> 00:23:17.039 after your initial thorough clinical and imaging 00:23:17.039 --> 00:23:19.619 workup. These are the cases that truly demand 00:23:19.619 --> 00:23:21.900 specialist input to ensure optimal outcomes. 00:23:22.240 --> 00:23:25.559 That's a truly comprehensive and incredibly practical 00:23:25.559 --> 00:23:29.039 roadmap for diagnosis, Professor. It really demystifies 00:23:29.039 --> 00:23:31.849 the initial clinical encounter. So once we've 00:23:31.849 --> 00:23:34.210 accurately diagnosed an ankle sprain and we've 00:23:34.210 --> 00:23:36.430 got a clear picture of its type and severity, 00:23:36.890 --> 00:23:39.670 the next critical hurdle is effective management. 00:23:40.230 --> 00:23:42.670 How do we best approach treatment from those 00:23:42.670 --> 00:23:44.809 initial conservative measures that apply to the 00:23:44.809 --> 00:23:47.450 vast majority of patients to considering surgical 00:23:47.450 --> 00:23:49.990 intervention for those specific, often more complex 00:23:49.990 --> 00:23:52.769 circumstances? I imagine it's a careful balance, 00:23:52.809 --> 00:23:55.329 particularly with athletes keen to return to 00:23:55.329 --> 00:23:58.190 play. It is indeed a careful balance and a multi 00:23:58.190 --> 00:24:00.660 -phased approach is key. For the overwhelming 00:24:00.660 --> 00:24:02.740 majority of low ankle sprains, including many 00:24:02.740 --> 00:24:05.559 severe grade three ligament tears, robust and 00:24:05.559 --> 00:24:07.920 effective healing can absolutely be achieved 00:24:07.920 --> 00:24:10.200 without the need for surgery provided they are 00:24:10.200 --> 00:24:12.859 appropriately immobilized initially and crucially 00:24:12.859 --> 00:24:16.000 diligently rehabilitated. So non -operative first 00:24:16.000 --> 00:24:19.099 for most. The vast majority. Non -operative treatment 00:24:19.099 --> 00:24:21.619 typically begins with initial management or phase 00:24:21.619 --> 00:24:24.579 one. This is where the well -known RICE protocol 00:24:24.579 --> 00:24:28.470 has historically held sway. Rest. Advise patients 00:24:28.470 --> 00:24:30.730 to avoid weight bearing on the injured ankle 00:24:30.730 --> 00:24:32.809 or resuming sports activities that aggravate 00:24:32.809 --> 00:24:35.650 it. For more severe sprains, particularly grade 00:24:35.650 --> 00:24:38.210 two or three, crutches may be recommended for 00:24:38.210 --> 00:24:40.609 a period to avoid weight bearing completely and 00:24:40.609 --> 00:24:44.029 allow initial healing. Ice. Immediate application 00:24:44.029 --> 00:24:46.190 helps significantly to reduce swelling and pain. 00:24:46.750 --> 00:24:49.109 Recommend applying an ice pack for 20 to 30 minutes, 00:24:49.289 --> 00:24:51.549 three to four times daily, ensuring it's wrapped 00:24:51.549 --> 00:24:53.730 in a cloth to prevent direct skin contact and 00:24:53.730 --> 00:24:57.039 potential ice burns. Compression. Using elastic 00:24:57.039 --> 00:24:59.559 bandages and ace wrap or compression stocking 00:24:59.559 --> 00:25:01.839 can help to both immobilize and support the ankle 00:25:01.839 --> 00:25:04.859 while also actively managing edema. Elevation. 00:25:05.220 --> 00:25:06.859 Instruct patients to raise their ankle above 00:25:06.859 --> 00:25:08.980 heart level as often as possible during the first 00:25:08.980 --> 00:25:11.819 48 hours. This uses gravity to help drain excess 00:25:11.819 --> 00:25:13.799 fluid and control swelling. Right, see everyone 00:25:13.799 --> 00:25:17.059 knows it. Everyone knows it. Now here's a critical 00:25:17.059 --> 00:25:20.089 insight that's shifting clinical practice. While 00:25:20.089 --> 00:25:23.109 rice has been a cornerstone for decades, recent 00:25:23.109 --> 00:25:25.549 evidence suggests its isolated effectiveness 00:25:25.799 --> 00:25:28.039 particularly the R for rest and the I for ice, 00:25:28.500 --> 00:25:30.519 is somewhat limited in terms of accelerating 00:25:30.519 --> 00:25:33.259 definitive healing beyond immediate pain and 00:25:33.259 --> 00:25:35.700 swelling control. Oh, interesting. So rice alone 00:25:35.700 --> 00:25:39.000 isn't the whole story. Not entirely. Strong evidence 00:25:39.000 --> 00:25:42.240 primarily supports cryotherapy, or ice, when 00:25:42.240 --> 00:25:44.200 combined with early controlled exercise therapy 00:25:44.200 --> 00:25:46.940 for truly improving functional outcomes. So it's 00:25:46.940 --> 00:25:49.759 not simply rest and ice. It's ice and move it 00:25:49.759 --> 00:25:52.220 judiciously. Bice and movement. Controlled movement, 00:25:52.400 --> 00:25:54.680 yes. It's also important to advise patients to 00:25:54.680 --> 00:25:58.000 avoid in the first two to three days. Heat, alcohol 00:25:58.000 --> 00:26:00.819 running, or excessive activity and massage, as 00:26:00.819 --> 00:26:02.640 these can exacerbate swelling and bleeding in 00:26:02.640 --> 00:26:05.500 the acute phase. Avoid harm, remember rice, with 00:26:05.500 --> 00:26:09.279 caveats. Exactly. Regarding immobilization, a 00:26:09.279 --> 00:26:11.460 short period of immobilization, perhaps around 00:26:11.460 --> 00:26:13.859 one week, in a walking boot, in an air cast, 00:26:13.940 --> 00:26:16.400 or a walking cast, may be required, particularly 00:26:16.400 --> 00:26:19.240 for gray Daseki's brains, or those with significant 00:26:19.240 --> 00:26:22.259 pain. For grade 3 sprains, a slightly longer 00:26:22.259 --> 00:26:24.599 period of casting or bracing for 10 -14 days 00:26:24.599 --> 00:26:27.500 with strict non -weight -bearing might be beneficial 00:26:27.500 --> 00:26:29.940 to protect the completely torn ligament in its 00:26:29.940 --> 00:26:33.279 initial healing phase. So immobilize, but not 00:26:33.279 --> 00:26:35.440 for too long? That's the key. The overarching 00:26:35.440 --> 00:26:37.319 principle that has emerged strongly in the last 00:26:37.319 --> 00:26:39.839 decade is that early mobilization generally facilitates 00:26:39.839 --> 00:26:42.420 a better and quicker recovery, leading to superior 00:26:42.420 --> 00:26:44.539 functional outcomes and less stiffness in the 00:26:44.539 --> 00:26:47.000 long run. So the immobilization period should 00:26:47.000 --> 00:26:49.839 always be as brief as clinically necessary, guided 00:26:49.839 --> 00:26:51.920 by the patient's pain levels and the stability 00:26:51.920 --> 00:26:54.819 of the injury. For medication, non -steroidal 00:26:54.819 --> 00:26:58.180 anti -inflammatory drugs or NSAIDs, such as ibuprofen, 00:26:58.220 --> 00:27:01.359 naproxen, or Celecoxib, are widely used for pain 00:27:01.359 --> 00:27:04.099 relief and swelling reduction. They are generally 00:27:04.099 --> 00:27:06.259 preferred over narcotic painkillers for mild 00:27:06.259 --> 00:27:08.680 to moderate sprains, as they improve function 00:27:08.680 --> 00:27:11.440 by addressing both pain and inflammation. Standard 00:27:11.440 --> 00:27:15.460 NSAIDs. Yes. However, And here's another nuanced 00:27:15.460 --> 00:27:17.740 insight for our listeners. It's worth noting 00:27:17.740 --> 00:27:21.140 the potential for NSI's to actually delay the 00:27:21.140 --> 00:27:23.859 natural healing process in some contexts. This 00:27:23.859 --> 00:27:26.039 is because they suppress the inflammatory response, 00:27:26.420 --> 00:27:29.559 which ironically is a necessary and initial component 00:27:29.559 --> 00:27:31.779 of the body's natural tissue repair process. 00:27:32.140 --> 00:27:34.400 Right. Inflammation is part of healing. It is. 00:27:34.680 --> 00:27:36.819 So while they provide symptomatic relief, we 00:27:36.819 --> 00:27:38.700 need to be mindful of this potential trade -off, 00:27:38.839 --> 00:27:41.059 especially in the very early stages of healing 00:27:41.059 --> 00:27:44.019 for more severe sprains. The true cornerstone 00:27:44.019 --> 00:27:46.059 of long -term recovery, particularly from phase 00:27:46.059 --> 00:27:48.619 two onwards, is dedicated physical therapy and 00:27:48.619 --> 00:27:51.319 rehabilitation. This is absolutely crucial irrespective 00:27:51.319 --> 00:27:54.200 of the initial severity. Physio is key. Absolutely. 00:27:54.839 --> 00:27:58.000 The early phase, phase two, or functional rehabilitation, 00:27:58.680 --> 00:28:01.039 begins once the initial acute swelling and pain 00:28:01.039 --> 00:28:03.680 have subsided, usually within a few days to a 00:28:03.680 --> 00:28:06.420 week. This involves gentle motion exercises, 00:28:06.859 --> 00:28:08.599 progressing quickly to isometric strengthening, 00:28:09.099 --> 00:28:11.539 proprioception training, and activity -specific 00:28:11.539 --> 00:28:14.539 exercises. It's vital that any rigid immobilization 00:28:14.539 --> 00:28:16.640 is discontinued at this stage to prevent joint 00:28:16.640 --> 00:28:19.339 stiffness and muscle atrophy. The goal here is 00:28:19.339 --> 00:28:22.490 to regain a pain -free range of motion. Strengthening 00:28:22.490 --> 00:28:25.170 phase, phase three, commences once full range 00:28:25.170 --> 00:28:27.150 of motion is achieved and pain is well under 00:28:27.150 --> 00:28:29.910 control. The primary focus here is on strengthening 00:28:29.910 --> 00:28:32.309 the peroneal muscles, the muscles on the outside 00:28:32.309 --> 00:28:34.930 of your lower leg, which are key dynamic stabilizers 00:28:34.930 --> 00:28:37.309 of the ankle and actively resistant version. 00:28:37.569 --> 00:28:41.329 Strengthening those outer muscles. Crucial. Neuromuscular 00:28:41.329 --> 00:28:43.950 training, which helps improve the brain's communication 00:28:43.950 --> 00:28:47.089 with the muscles, is integrated. Gradual incorporation 00:28:47.089 --> 00:28:49.869 of resistance exercises using bands, weights, 00:28:49.930 --> 00:28:53.339 or body weight is key. Water -based exercises 00:28:53.339 --> 00:28:56.220 like aqua jogging or exercises in a pool can 00:28:56.220 --> 00:28:58.380 be incredibly useful for patients who are still 00:28:58.380 --> 00:29:00.880 experiencing pain during land -based weight -bearing 00:29:00.880 --> 00:29:04.259 exercises as the buoyancy reduces load. Hydrotherapy 00:29:04.259 --> 00:29:07.440 can be great. Very helpful. Proprioception balance 00:29:07.440 --> 00:29:09.920 training is an absolutely essential component, 00:29:10.380 --> 00:29:12.660 particularly given that poor balance is a significant 00:29:12.660 --> 00:29:15.400 well -established risk factor for recurrent sprains 00:29:15.400 --> 00:29:18.180 and chronic instability. These exercises are 00:29:18.180 --> 00:29:20.119 designed to enhance the body's awareness of joint 00:29:20.119 --> 00:29:22.799 position and movement. Think of simple exercises 00:29:22.799 --> 00:29:24.559 like standing on the affected foot with eyes 00:29:24.559 --> 00:29:27.259 open, then progressing to eyes closed. Wobble 00:29:27.259 --> 00:29:30.259 boards and things like that. Exactly. Or using 00:29:30.259 --> 00:29:32.559 unstable surfaces like a wobble board or foam 00:29:32.559 --> 00:29:35.430 pad. These drills are not just about balance. 00:29:36.089 --> 00:29:37.990 They help to re -educate the nervous system, 00:29:38.329 --> 00:29:40.950 training faster, more reactive responses from 00:29:40.950 --> 00:29:43.230 the peroneal muscles during dynamic activities, 00:29:43.650 --> 00:29:46.210 helping the ankle to catch itself before it rolls. 00:29:46.970 --> 00:29:48.970 Endurance and agility exercises are gradually 00:29:48.970 --> 00:29:51.470 introduced once the patient is pain -free and 00:29:51.470 --> 00:29:54.059 has achieved good strength and balance. Examples 00:29:54.059 --> 00:29:56.099 include progressively smaller figure of eight 00:29:56.099 --> 00:29:58.819 running drills, side -to -side shuffles, or ladder 00:29:58.819 --> 00:30:01.339 drills. These improve agility, ankle strength, 00:30:01.559 --> 00:30:04.000 and calf endurance, simulating sport -specific 00:30:04.000 --> 00:30:06.859 movements. A functional brace that specifically 00:30:06.859 --> 00:30:09.240 controls inversion and eversion is typically 00:30:09.240 --> 00:30:10.859 recommended for use during the strengthening 00:30:10.859 --> 00:30:13.240 period and often as a prophylactic measure for 00:30:13.240 --> 00:30:15.539 high -risk activities, particularly in the early 00:30:15.539 --> 00:30:18.200 return to sport phase. Bracing for sport. Often 00:30:18.200 --> 00:30:21.299 advisable, especially initially. In terms of 00:30:21.299 --> 00:30:23.859 outcomes for non -operative treatment, consistent 00:30:23.859 --> 00:30:26.240 evidence shows that early functional rehabilitation 00:30:26.240 --> 00:30:28.920 consistently leads to the quickest return to 00:30:28.920 --> 00:30:31.660 physical activity and superior long -term outcomes. 00:30:31.950 --> 00:30:34.630 While supervised physical therapy shows early 00:30:34.630 --> 00:30:37.170 benefits in terms of patient confidence and adherence, 00:30:37.650 --> 00:30:39.710 there isn't convincing evidence of a significant 00:30:39.710 --> 00:30:42.210 long -term difference in outcome compared to 00:30:42.210 --> 00:30:44.529 a well -structured unsupervised home program 00:30:44.529 --> 00:30:47.250 for mild to moderate sprains, provided the patient 00:30:47.250 --> 00:30:50.109 is compliant. So home exercises can work well 00:30:50.109 --> 00:30:53.390 if done properly. They certainly can. Also, it's 00:30:53.390 --> 00:30:55.130 an important point for clinicians that there's 00:30:55.130 --> 00:30:57.130 no convincing evidence that the future development 00:30:57.130 --> 00:30:59.410 of chronic ankle instability can be reliably 00:30:59.410 --> 00:31:02.769 predicted solely by history, acute physical examination, 00:31:03.269 --> 00:31:06.190 or initial radiographic parameters. So a seemingly 00:31:06.190 --> 00:31:08.650 minor sprain can still lead to long -term issues 00:31:08.650 --> 00:31:10.970 if not rehabilitated properly. You can't always 00:31:10.970 --> 00:31:13.910 tell at the start. Not reliably, no. Return to 00:31:13.910 --> 00:31:16.369 play or activity varies significantly and must 00:31:16.369 --> 00:31:19.029 be individualized. It depends heavily on the 00:31:19.029 --> 00:31:21.670 sprains grade, whether there's syndesmosis involvement 00:31:21.670 --> 00:31:24.549 as high ankle sprains take longer, any associated 00:31:24.549 --> 00:31:27.309 injuries, and critically, the patient's compliance 00:31:27.309 --> 00:31:29.829 and progression through the rehabilitation program. 00:31:30.990 --> 00:31:33.910 As a general guideline, Grade 1 sprains typically 00:31:33.910 --> 00:31:37.210 allow return within 1 -2 weeks. Grade 2 sprains 00:31:37.210 --> 00:31:40.369 usually take 2 -4 weeks. Grade 3 sprains generally 00:31:40.369 --> 00:31:42.910 require 4 -8 weeks. And high ankle sprains? They 00:31:42.910 --> 00:31:45.349 take longer. For high ankle sprains managed with 00:31:45.349 --> 00:31:47.569 immobilization, recovery can be 6 -12 weeks. 00:31:48.430 --> 00:31:50.650 If screw fixation is required for a high ankle 00:31:50.650 --> 00:31:53.170 sprain to stabilize the syndesmosis, it could 00:31:53.170 --> 00:31:55.190 even be a season -ending injury for an athlete 00:31:55.190 --> 00:31:57.769 requiring 4 -6 months before return to sport. 00:31:58.379 --> 00:32:00.380 Overall, recovery can range from as little as 00:32:00.380 --> 00:32:03.000 two weeks for very minor sprains to three, six 00:32:03.000 --> 00:32:05.339 months for more severe complex injuries. Quite 00:32:05.339 --> 00:32:07.759 a range. A very wide range. Now, for operative 00:32:07.759 --> 00:32:10.119 treatment, it is thankfully rarely required for 00:32:10.119 --> 00:32:12.619 the majority of ankle sprains. Surgery is typically 00:32:12.619 --> 00:32:15.259 considered only for specific, well -defined circumstances. 00:32:15.500 --> 00:32:17.700 When does surgery come into play? The primary 00:32:17.700 --> 00:32:20.180 indications for surgery include persistent pain 00:32:20.180 --> 00:32:24.259 and chronic ankle instability. Despite an extensive 00:32:24.259 --> 00:32:26.599 and rigorous course of non -operative management, 00:32:27.039 --> 00:32:29.880 and we're talking about months of dedicated supervised 00:32:29.880 --> 00:32:32.859 rehabilitation, not just a few weeks. After failed 00:32:32.859 --> 00:32:35.119 conservative treatment. Yes, genuine failure 00:32:35.119 --> 00:32:38.059 despite best efforts. It might also be considered 00:32:38.059 --> 00:32:40.759 for great third sprains if there's a significant 00:32:40.759 --> 00:32:42.759 bony avulsion, meaning a piece of bone has been 00:32:42.759 --> 00:32:45.279 pulled off by the ligament. Certain high ankle 00:32:45.279 --> 00:32:48.420 sprains with clear tibiofibular diastasis, which 00:32:48.420 --> 00:32:50.779 is that pathological widening or separation between 00:32:50.779 --> 00:32:53.259 the tibia and fibula, often indicating a complete 00:32:53.259 --> 00:32:55.960 syndesmotic disruption, are also surgical candidates. 00:32:56.339 --> 00:32:58.980 Unstable high ankle sprain. Correct. Furthermore, 00:32:59.220 --> 00:33:01.460 if there are associated significant injuries 00:33:01.460 --> 00:33:04.359 identified, such as osteochondral lesions, cartilage 00:33:04.359 --> 00:33:07.359 damage on the talus, ruptured peroneal or other 00:33:07.359 --> 00:33:09.700 tendons, or significant impingement syndromes 00:33:09.700 --> 00:33:12.259 that don't respond to conservative care, then 00:33:12.259 --> 00:33:15.019 surgery may be necessary to address these concomitant 00:33:15.019 --> 00:33:19.339 issues. As for the types of surgery, arthroscopy 00:33:19.339 --> 00:33:22.220 is a minimally invasive keyhole procedure, often 00:33:22.220 --> 00:33:24.380 performed prior to open ligament reconstruction. 00:33:24.680 --> 00:33:27.299 It allows the surgeon to inspect the entire joint 00:33:27.299 --> 00:33:30.400 meticulously, identify and debride any impinging 00:33:30.400 --> 00:33:33.259 scar tissue or synovitis, or remove loose fragments 00:33:33.259 --> 00:33:35.559 of bone or cartilage that might be causing ongoing 00:33:35.559 --> 00:33:37.880 pain, catching, or mechanical symptoms. We look 00:33:37.880 --> 00:33:40.400 inside first. Often very helpful, yes. It's an 00:33:40.400 --> 00:33:42.579 excellent diagnostic tool as well as therapeutic. 00:33:42.910 --> 00:33:45.410 For the ligament repair or reconstruction itself, 00:33:45.430 --> 00:33:47.730 there are two main approaches. The gold standard 00:33:47.730 --> 00:33:49.890 for chronic lateral ankle instability is the 00:33:49.890 --> 00:33:52.470 anatomic reconstruction, famously exemplified 00:33:52.470 --> 00:33:54.890 by the Gould modification of the Brostrum procedure. 00:33:55.390 --> 00:33:58.650 That's the one. This procedure involves shortening 00:33:58.650 --> 00:34:02.509 and reinserting the ATFL and CFL to their anatomical 00:34:02.509 --> 00:34:05.190 origins and insertions, often reinforced with 00:34:05.190 --> 00:34:08.110 the inferior extensor retinaculum and distal 00:34:08.110 --> 00:34:11.030 fibular periosteum, which are local soft tissues 00:34:11.030 --> 00:34:13.630 providing additional strength. In more recent 00:34:13.630 --> 00:34:16.269 years, suture tape augmentation, where a strong 00:34:16.269 --> 00:34:18.829 tape is placed alongside the repair, has been 00:34:18.829 --> 00:34:21.070 shown to further increase the strength and early 00:34:21.070 --> 00:34:23.769 stability of this repair, allowing for potentially 00:34:23.769 --> 00:34:26.010 faster rehabilitation. Adding extra support. 00:34:26.550 --> 00:34:29.010 Exactly. A critical point to remember with this 00:34:29.010 --> 00:34:31.030 procedure is that if the ligaments are overtly 00:34:31.030 --> 00:34:33.590 lightened, it can unfortunately lead to a restricted 00:34:33.590 --> 00:34:36.090 range of dorsiflexion post -operatively causing 00:34:36.090 --> 00:34:38.860 stiffness. The outcomes for the Brostrom Gold 00:34:38.860 --> 00:34:41.219 are generally very good, with good to excellent 00:34:41.219 --> 00:34:43.880 results reported in about 90 % of cases. High 00:34:43.880 --> 00:34:47.099 success rate. Generally, yes. Alternatively, 00:34:47.639 --> 00:34:49.400 particularly in cases of severe instability, 00:34:50.079 --> 00:34:52.440 failed previous repairs, or significant tissue 00:34:52.440 --> 00:34:55.739 laxity, there are tendon transfer or tenodesis 00:34:55.739 --> 00:34:58.920 procedures. Examples include the Watson -Jones, 00:34:59.260 --> 00:35:01.800 Christman -Snoek, Colville, or Evans techniques. 00:35:02.039 --> 00:35:04.780 These are considered non -anatomic reconstructions 00:35:04.780 --> 00:35:07.280 because they don't recreate the original ligament 00:35:07.280 --> 00:35:09.739 anatomy directly. Instead, they use a segment 00:35:09.739 --> 00:35:13.059 of a healthy local tendon, often one of the peroneal 00:35:13.059 --> 00:35:15.360 tendons, which is then passed through bone tunnels 00:35:15.360 --> 00:35:18.840 to create a new functional restraint. Using a 00:35:18.840 --> 00:35:20.900 tendon instead of repairing the ligament. Correct. 00:35:21.139 --> 00:35:22.940 It's absolutely critical that any pre -existing 00:35:22.940 --> 00:35:25.320 foot or ankle malalignment, such as a hindfoot 00:35:25.320 --> 00:35:27.619 virus where the heel turns inward, is identified 00:35:27.619 --> 00:35:29.659 and corrected, often assessed with something 00:35:29.659 --> 00:35:32.420 like Coleman block testing before these procedures 00:35:32.420 --> 00:35:34.900 are undertaken, as malalignment can jeopardize 00:35:34.900 --> 00:35:36.639 the success of the reconstruction. You need to 00:35:36.639 --> 00:35:38.989 fix the alignment first. Absolutely essential. 00:35:39.510 --> 00:35:41.550 A common complication with these non -anatomic 00:35:41.550 --> 00:35:44.929 reconstructions due to their altered biomechanics 00:35:44.929 --> 00:35:47.989 can be subtalar stiffness, which can affect foot 00:35:47.989 --> 00:35:51.949 mobility. Postoperative recovery following surgery 00:35:51.949 --> 00:35:54.590 invariably involves a period of immobilization 00:35:54.590 --> 00:35:57.289 in a cast or protective boot typically for four 00:35:57.289 --> 00:36:00.110 to six weeks to safeguard the delicate repaired 00:36:00.110 --> 00:36:03.389 ligaments during their initial healing. Strict 00:36:03.389 --> 00:36:05.369 adherence to non -weight -bearing protocols during 00:36:05.369 --> 00:36:08.570 this crucial initial phase is absolutely critical 00:36:08.570 --> 00:36:11.469 to prevent re -tear of the surgical repair. Protecting 00:36:11.469 --> 00:36:14.409 the repair. Vitally important. Rehabilitation 00:36:14.409 --> 00:36:17.250 then commences, focusing intently on regaining 00:36:17.250 --> 00:36:19.570 strength and range of motion, similar in principle 00:36:19.570 --> 00:36:22.150 to conservative rehab, but often more gradual 00:36:22.150 --> 00:36:24.909 initially. Recovery takes weeks to many months, 00:36:25.250 --> 00:36:27.150 depending on the extent of the original injury 00:36:27.150 --> 00:36:30.250 and the specific type of surgery performed. While 00:36:30.250 --> 00:36:32.690 some newer mobilization protocols advocate for 00:36:32.690 --> 00:36:34.610 earlier postoperative mobilization to improve 00:36:34.610 --> 00:36:37.250 functional scores, it's a careful balance, as 00:36:37.250 --> 00:36:39.449 they can also potentially lead to increased ankle 00:36:39.449 --> 00:36:41.889 laxity and a slightly higher risk of wound healing 00:36:41.889 --> 00:36:44.969 complications if not managed meticulously. That 00:36:44.969 --> 00:36:47.329 distinction between non -operative and operative 00:36:47.329 --> 00:36:49.869 strategies and the intricate nuances within each 00:36:49.869 --> 00:36:52.809 is incredibly insightful, profess. It highlights 00:36:52.809 --> 00:36:55.329 the depth of decision -making involved. But as 00:36:55.329 --> 00:36:57.610 the old saying goes, and it holds so true here, 00:36:57.849 --> 00:37:01.150 prevention is always better than cure. How can 00:37:01.150 --> 00:37:03.469 we as clinicians truly empower our patients, 00:37:03.690 --> 00:37:05.969 especially our athletes, like our hypothetical 00:37:05.969 --> 00:37:08.469 netball player Sarah, who just wants to get back 00:37:08.469 --> 00:37:10.949 on court without constant fear to proactively 00:37:10.949 --> 00:37:13.489 reduce their risk of both initial ankle sprains 00:37:13.489 --> 00:37:16.010 and critically those debilitating recurrent injuries? 00:37:16.469 --> 00:37:19.239 This is indeed a vital area. and one where we 00:37:19.239 --> 00:37:21.340 can make a tremendous impact on a patient's long 00:37:21.340 --> 00:37:23.679 -term quality of life. It genuinely requires 00:37:23.679 --> 00:37:26.179 a multifaceted approach, empowering patients 00:37:26.179 --> 00:37:28.179 to be proactive and consistently maintaining 00:37:28.179 --> 00:37:30.380 their ankle strength, balance, and flexibility. 00:37:30.980 --> 00:37:33.500 For us as clinicians, the focus must be on targeting 00:37:33.500 --> 00:37:36.360 and modifying any identifiable intrinsic and 00:37:36.360 --> 00:37:39.019 extrinsic risk factors. Tackling those risk factors 00:37:39.019 --> 00:37:41.980 we talked about. Exactly. One of the most fundamental, 00:37:42.199 --> 00:37:45.400 yet often overlooked, aspects is footwear selection. 00:37:45.690 --> 00:37:48.550 This is absolutely crucial for providing adequate 00:37:48.550 --> 00:37:51.309 support and stability. For individuals whose 00:37:51.309 --> 00:37:53.969 feet pronate excessively or who have naturally 00:37:53.969 --> 00:37:57.369 low arches, often referred to as flat feet, advise 00:37:57.369 --> 00:37:59.750 them to opt for shoes that offer robust arch 00:37:59.750 --> 00:38:02.110 and front foot support, coupled with a stable, 00:38:02.409 --> 00:38:04.710 firm heel counter. Supporting the flat foot? 00:38:05.130 --> 00:38:07.989 Yes, controlling that inward roll. Conversely, 00:38:08.070 --> 00:38:10.989 those with stiffer feet or high arches, a cavalvaris 00:38:10.989 --> 00:38:13.809 alignment, for example, may benefit more from 00:38:13.809 --> 00:38:15.909 cushioned and softer platforms, as their feet 00:38:15.909 --> 00:38:18.829 are inherently less shock -absorbent. It goes 00:38:18.829 --> 00:38:20.489 without saying that sport -specific shoes are 00:38:20.489 --> 00:38:22.789 highly recommended. A runner needs running shoes 00:38:22.789 --> 00:38:25.349 designed for gait, a basketball or netball player 00:38:25.349 --> 00:38:27.469 needs court shoes with good lateral support and 00:38:27.469 --> 00:38:30.070 grip, and so on. Right tool for the job. Precisely. 00:38:30.219 --> 00:38:32.860 General cross -training shoes, while versatile, 00:38:33.099 --> 00:38:35.340 may not offer the precise support and stability 00:38:35.340 --> 00:38:37.380 needed for specific high -demand activities, 00:38:37.840 --> 00:38:40.320 and importantly, advise regular replacement of 00:38:40.320 --> 00:38:42.300 athletic shoes typically every six months for 00:38:42.300 --> 00:38:44.840 regular runners, or even more frequently if the 00:38:44.840 --> 00:38:47.280 tread wears out or the shoe's cushioning and 00:38:47.280 --> 00:38:50.059 support degrade prematurely. A simple check is 00:38:50.059 --> 00:38:52.460 if the midsole feels flat or compressed. Don't 00:38:52.460 --> 00:38:54.840 wear worn -out trainers. A simple but effective 00:38:54.840 --> 00:38:58.260 message. Beyond footwear, Exercise -based prevention 00:38:58.260 --> 00:39:01.679 truly forms the core of a robust program. Strengthening 00:39:01.679 --> 00:39:04.099 exercises are key to improving dynamic ankle 00:39:04.099 --> 00:39:06.639 stability. This includes simple calf raises, 00:39:07.320 --> 00:39:09.820 resistance band ankle exercises to target various 00:39:09.820 --> 00:39:12.699 planes of motion, dorsiflexion, plantar flexion, 00:39:12.940 --> 00:39:15.619 inversion, and aversion, and critically specific 00:39:15.619 --> 00:39:17.880 and dedicated strengthening of the evertoor muscles, 00:39:18.039 --> 00:39:20.639 particularly the peroneals. Again, those peroneal 00:39:20.639 --> 00:39:23.460 muscles. They're the active stabilizers, resisting 00:39:23.460 --> 00:39:26.849 that inversion force. Propreception exercises 00:39:26.849 --> 00:39:29.710 are absolutely essential. Given that poor balance 00:39:29.710 --> 00:39:32.489 and diminished joint awareness are such significant 00:39:32.489 --> 00:39:35.110 risk factors for recurrent sprains, exercises 00:39:35.110 --> 00:39:37.369 that enhance the conscious and subconscious awareness 00:39:37.369 --> 00:39:39.829 of joint position and movement are paramount. 00:39:40.030 --> 00:39:42.849 Think of single leg balance exercises. Progressively 00:39:42.849 --> 00:39:45.170 perform first with eyes open, then with eyes 00:39:45.170 --> 00:39:48.090 closed to remove visual cues, or using unstable 00:39:48.090 --> 00:39:50.429 surfaces like a wobble board, balance disc, or 00:39:50.429 --> 00:39:53.349 foam pad. Training that balance reaction. Exactly. 00:39:53.579 --> 00:39:56.460 These drills are profound. They help to re -educate 00:39:56.460 --> 00:39:59.519 the nervous system, training faster, more accurate 00:39:59.519 --> 00:40:01.960 neuromuscular responses from the peroneal and 00:40:01.960 --> 00:40:04.739 other stabilizing muscles during dynamic activities, 00:40:05.219 --> 00:40:07.460 helping the ankle to catch itself and correct 00:40:07.460 --> 00:40:09.980 its position milliseconds before a sprain occurs. 00:40:10.940 --> 00:40:13.119 A structured warm -up routine, including dynamic 00:40:13.119 --> 00:40:15.260 stretches and light cardiovascular activity targeting 00:40:15.260 --> 00:40:17.960 the lower limbs, should always proceed any physical 00:40:17.960 --> 00:40:20.510 activity. This prepares the muscles and ligaments 00:40:20.510 --> 00:40:23.050 for the demands of the activity, increasing blood 00:40:23.050 --> 00:40:25.710 flow and elasticity, thereby reducing injury 00:40:25.710 --> 00:40:28.429 risk. And for those returning to sport or higher 00:40:28.429 --> 00:40:30.889 -level activities, incorporating progressive 00:40:30.889 --> 00:40:32.909 drills like quick support drills, shuttle runs, 00:40:32.989 --> 00:40:35.849 and dynamic landings can further enhance neuromuscular 00:40:35.849 --> 00:40:38.670 control, agility, and stability in sport -specific 00:40:38.670 --> 00:40:41.329 contexts. These drills mimic the demands of their 00:40:41.329 --> 00:40:44.610 sport, building confidence and resilience. Maintenance 00:40:44.610 --> 00:40:46.849 and activity modification are also critical for 00:40:46.849 --> 00:40:49.619 long -term success. Encourage patients to regularly 00:40:49.619 --> 00:40:51.719 include balance and strengthening exercises in 00:40:51.719 --> 00:40:53.760 their routine, perhaps two to three times per 00:40:53.760 --> 00:40:55.960 week, even when they feel completely well and 00:40:55.960 --> 00:40:58.500 pain -free. Keep doing the exercises. It isn't 00:40:58.500 --> 00:41:01.320 just rehabilitation. It's preventative maintenance. 00:41:01.980 --> 00:41:04.300 Furthermore, advise them to be mindful of and, 00:41:04.340 --> 00:41:07.079 whenever possible, avoid high -risk situations, 00:41:07.400 --> 00:41:10.579 stepping on uneven or slippery surfaces, especially 00:41:10.579 --> 00:41:13.440 when fatigued or distracted, significantly increases 00:41:13.440 --> 00:41:16.960 vulnerability to injury. Sometimes, just being 00:41:16.960 --> 00:41:19.219 aware of your environment can prevent an incident. 00:41:19.860 --> 00:41:21.719 Finally, when we consider return to activity 00:41:21.719 --> 00:41:24.320 for athletes like Sarah, it must be a meticulously 00:41:24.320 --> 00:41:26.780 gradual transition to sport -specific activities, 00:41:27.179 --> 00:41:29.300 ensuring full functional recovery, confidence, 00:41:29.699 --> 00:41:31.699 and assessed readiness before resuming previous 00:41:31.699 --> 00:41:34.260 intensity levels. For athletes with a history 00:41:34.260 --> 00:41:36.679 of prior sprains, a comprehensive prevention 00:41:36.679 --> 00:41:39.329 program is particularly important. And this may 00:41:39.329 --> 00:41:41.869 indeed include the consistent use of semi -rigid 00:41:41.869 --> 00:41:44.230 ankle orthosis or taping, especially for those 00:41:44.230 --> 00:41:46.789 who demonstrate a cavovirus foot alignment to 00:41:46.789 --> 00:41:48.550 provide that essential additional mechanical 00:41:48.550 --> 00:41:51.329 support and proprioceptive feedback. Bracing 00:41:51.329 --> 00:41:53.570 or taping for those at higher risk? It can make 00:41:53.570 --> 00:41:55.530 a real difference. Implementing these measures 00:41:55.530 --> 00:41:57.590 consistently can dramatically reduce the risk 00:41:57.590 --> 00:41:59.909 of both initial ankle sprains and, crucially, 00:42:00.110 --> 00:42:02.309 that frustrating cycle of recurrence. That's 00:42:02.309 --> 00:42:04.550 a truly powerful message on Prevention Prof, 00:42:04.969 --> 00:42:07.429 emphasizing that our role extends far beyond 00:42:07.429 --> 00:42:10.010 merely treating the acute injury. It's about 00:42:10.010 --> 00:42:13.070 empowering patients to stay robust. But even 00:42:13.070 --> 00:42:15.750 with the best care, diligent rehab, and robust 00:42:15.750 --> 00:42:19.150 prevention strategies, complications can, unfortunately, 00:42:19.429 --> 00:42:22.789 arise. What are the potential long -term complications 00:42:22.789 --> 00:42:25.530 of ankle sprains, and how do we, as clinicians, 00:42:25.869 --> 00:42:28.289 best identify and manage them to ensure optimal 00:42:28.289 --> 00:42:30.750 patient outcomes, avoiding that debilitating 00:42:30.750 --> 00:42:33.389 cycle of reinjury and chronic issues? This is 00:42:33.389 --> 00:42:35.510 a critical discussion, because while the majority 00:42:35.510 --> 00:42:38.150 of ankle sprains do heal well with proper management, 00:42:38.489 --> 00:42:40.730 we absolutely cannot overlook the significant 00:42:40.730 --> 00:42:42.820 potential for long -term term consequences if 00:42:42.820 --> 00:42:45.159 they are not correctly identified, managed or 00:42:45.159 --> 00:42:48.019 rehabilitated. The most immediate and significant 00:42:48.019 --> 00:42:49.960 risk following an ankle sprain, especially if 00:42:49.960 --> 00:42:51.920 the ankle isn't adequately healed and strengthened 00:42:51.920 --> 00:42:54.599 before resuming full physical activity, is re 00:42:54.599 --> 00:42:57.280 -injury. Going over on it again. Exactly. The 00:42:57.280 --> 00:42:59.519 structural integrity of the ankle has been compromised, 00:42:59.739 --> 00:43:02.440 even if subtly, making it inherently more susceptible 00:43:02.440 --> 00:43:05.719 to future sprains. Each re -injury can progressively 00:43:05.719 --> 00:43:09.030 worsen the joint's stability. A notable and pervasive 00:43:09.030 --> 00:43:11.710 long -term consequence affecting a significant 00:43:11.710 --> 00:43:14.409 proportion of patients is chronic ankle instability, 00:43:14.929 --> 00:43:18.170 or CAI. This develops in an estimated 15 % to 00:43:18.170 --> 00:43:20.829 20 % of patients, particularly when an initial 00:43:20.829 --> 00:43:23.289 ankle sprain, especially a severe one like a 00:43:23.289 --> 00:43:25.809 grade II or III, isn't allowed to heal completely 00:43:25.809 --> 00:43:28.630 or isn't adequately rehabilitated. 15 to 20 % 00:43:28.630 --> 00:43:32.139 is quite high. It is worryingly high. CAI is 00:43:32.139 --> 00:43:34.159 clinically characterized by persistent pain, 00:43:34.659 --> 00:43:36.880 ongoing swelling that seems to come and go, and 00:43:36.880 --> 00:43:39.619 most tellingly, the ankle repeatedly giving way 00:43:39.619 --> 00:43:41.860 or feeling profoundly unstable during weight 00:43:41.860 --> 00:43:43.880 -bearing activities, even on flat ground. That 00:43:43.880 --> 00:43:46.880 feeling of untrustworthiness. Precisely. It can 00:43:46.880 --> 00:43:49.659 be the result of a single, severe, inadequately 00:43:49.659 --> 00:43:52.239 rehabilitated sprain or the cumulative effect 00:43:52.239 --> 00:43:54.380 of multiple recurrence sprains that progressively 00:43:54.380 --> 00:43:57.190 stretch and weaken the ligaments. This chronic 00:43:57.190 --> 00:43:59.389 instability often leads to debilitating chronic 00:43:59.389 --> 00:44:01.809 pain, significant difficulty with activities 00:44:01.809 --> 00:44:04.389 like walking, running, or playing sports, and 00:44:04.389 --> 00:44:07.010 in the very long term dramatically increases 00:44:07.010 --> 00:44:09.469 the risk of developing early onset osteoarthritis 00:44:09.469 --> 00:44:11.670 and further damage to the underlying articular 00:44:11.670 --> 00:44:14.130 cartilage and bone within the joint due to abnormal 00:44:14.130 --> 00:44:16.769 loading patterns. Leading to arthritis down the 00:44:16.769 --> 00:44:19.570 line. A very real risk. When we look at long 00:44:19.570 --> 00:44:22.210 -term symptom statistics, the data is quite sobering. 00:44:22.239 --> 00:44:25.280 Research indicates that between 5 % and 46 % 00:44:25.280 --> 00:44:27.699 of patients report lingering pain years after 00:44:27.699 --> 00:44:30.559 their initial injury, and a staggering 33 % to 00:44:30.559 --> 00:44:34.199 55 % continue to experience a sensation of instability 00:44:34.199 --> 00:44:36.860 or giving way. Wow, over half in some studies. 00:44:37.760 --> 00:44:40.619 Yes. While acute pain typically decreases rapidly 00:44:40.619 --> 00:44:43.119 within the first two weeks post -injury, a notable 00:44:43.119 --> 00:44:46.820 percentage between 5 % and 33 % still report 00:44:46.820 --> 00:44:49.679 some level of pain even at one -year follow -up. 00:44:49.929 --> 00:44:52.789 This powerfully highlights that simply getting 00:44:52.789 --> 00:44:55.250 over the acute pain is by no means indicative 00:44:55.250 --> 00:44:57.929 of full recovery or resolution of the underlying 00:44:57.929 --> 00:45:00.750 issue. A significant and often overlooked cause 00:45:00.750 --> 00:45:03.090 of persistent chronic pain following an ankle 00:45:03.090 --> 00:45:06.019 sprain is actually a missed initial injury. These 00:45:06.019 --> 00:45:08.440 are often subtle but clinically significant pathologies 00:45:08.440 --> 00:45:11.300 that weren't picked up in the acute phase. Exactly. 00:45:12.199 --> 00:45:14.159 This can include missed fractures, such as those 00:45:14.159 --> 00:45:16.280 to the base of the fifth metatarsal, the anterior 00:45:16.280 --> 00:45:18.719 process of the calcaneus, or more subtle fractures 00:45:18.719 --> 00:45:21.139 of the lateral or posterior process of the talus. 00:45:21.539 --> 00:45:23.480 Osteochondral lesions, which are areas of damage 00:45:23.480 --> 00:45:25.599 to the articular cartilage and the underlying 00:45:25.599 --> 00:45:28.539 bone, most commonly affecting the talus. These 00:45:28.539 --> 00:45:31.260 can cause persistent pain, catching, or locking 00:45:31.260 --> 00:45:33.699 sensations. Injuries to the coronial tendons, 00:45:33.920 --> 00:45:35.960 which are key dynamic stabilizers. These can 00:45:35.960 --> 00:45:38.579 involve tenosynovitis, subluxation, or even full 00:45:38.579 --> 00:45:41.480 ruptures. An undiagnosed or inadequately treated 00:45:41.480 --> 00:45:44.099 syndesmosis injury, high ankle sprain, which 00:45:44.099 --> 00:45:46.119 as we discussed is far more severe and takes 00:45:46.119 --> 00:45:48.440 much longer to heal. Tarsal coalition, which 00:45:48.440 --> 00:45:50.840 is an abnormal fibrous, cartilaginous, or bony 00:45:50.840 --> 00:45:53.019 connection between two or more bones in the hindfoot. 00:45:53.219 --> 00:45:55.519 It can predispose to sprains and become symptomatic 00:45:55.519 --> 00:45:57.639 after trauma. Various impingement syndromes, 00:45:57.739 --> 00:46:00.179 such as anterior or anterolateral synovitis, 00:46:00.440 --> 00:46:01.980 inflammation of the joint lining in the front 00:46:01.980 --> 00:46:04.639 of the ankle, or impingement of the anterior 00:46:04.639 --> 00:46:07.099 or inferior tibiofibular ligaments from scar 00:46:07.099 --> 00:46:09.960 tissue. Interlying hindfoot varus malalignment, 00:46:10.179 --> 00:46:12.320 which places chronic stress on the lateral ankle 00:46:12.320 --> 00:46:15.400 structures. Or even stretch neuropraxia. where 00:46:15.400 --> 00:46:18.039 a peripheral nerve, often the superficial peroneal 00:46:18.039 --> 00:46:20.460 nerve, has been stretched or compressed during 00:46:20.460 --> 00:46:23.260 the spraying, leading to neuropathic pain or 00:46:23.260 --> 00:46:25.940 altered sensation in its distribution. Quite 00:46:25.940 --> 00:46:28.619 a list of potential missed problems. It requires 00:46:28.619 --> 00:46:32.340 a high index of suspicion. A truly thorough clinical 00:46:32.340 --> 00:46:35.179 evaluation is thus paramount to prevent these 00:46:35.179 --> 00:46:38.519 crucial oversights. The overall prognosis for 00:46:38.519 --> 00:46:40.960 ankle sprains is generally positive with proper 00:46:40.960 --> 00:46:43.980 treatment and dedicated rehabilitation. However, 00:46:44.239 --> 00:46:46.579 the ultimate success of recovery is highly dependent 00:46:46.579 --> 00:46:49.300 on the initial sprain grade, the presence or 00:46:49.300 --> 00:46:51.699 absence of any other associated injuries, both 00:46:51.699 --> 00:46:53.840 diagnosed and those that might have been initially 00:46:53.840 --> 00:46:56.659 missed, and, critically, the patient's unwavering 00:46:56.659 --> 00:46:59.320 commitment to their rehabilitation program. Patient 00:46:59.320 --> 00:47:02.260 compliance is vital. Absolutely vital. Incomplete 00:47:02.260 --> 00:47:04.940 rehabilitation is, without doubt, the most common 00:47:04.940 --> 00:47:07.780 single cause of chronic ankle instability and 00:47:07.780 --> 00:47:10.659 subsequent re -injury. Patients who discontinue 00:47:10.659 --> 00:47:13.260 their strengthening and balance exercises prematurely 00:47:13.260 --> 00:47:15.199 will inevitably find their injured ligaments 00:47:15.199 --> 00:47:18.400 and the surrounding dynamic stabilizers weaken, 00:47:18.659 --> 00:47:20.820 putting them at exceedingly high risk for future 00:47:20.820 --> 00:47:23.880 sprains. It's also crucial to counsel patients 00:47:23.880 --> 00:47:25.920 that while surgical interventions are sometimes 00:47:25.920 --> 00:47:28.360 absolutely necessary for chronic instability 00:47:28.360 --> 00:47:31.199 or other associated complications, they do carry 00:47:31.199 --> 00:47:33.659 their own inherent risks. These can include the 00:47:33.659 --> 00:47:35.980 general risk of surgery like infection or nerve 00:47:35.980 --> 00:47:38.460 damage, a potentially prolonged recovery period 00:47:38.460 --> 00:47:40.880 with strict immobilization, and the unfortunate 00:47:40.880 --> 00:47:43.059 possibility of some residual loss of ankle range 00:47:43.059 --> 00:47:45.579 of motion postoperatively, even with the best 00:47:45.579 --> 00:47:47.539 surgical technique. Surgery isn't without its 00:47:47.539 --> 00:47:50.260 own issues. Never. So the decision for surgery 00:47:50.260 --> 00:47:52.619 is always a careful considered one, weighing 00:47:52.619 --> 00:47:54.659 these risks and potential benefits against the 00:47:54.659 --> 00:47:56.519 patient's individual circumstances and goals. 00:47:57.440 --> 00:47:59.420 Our aim is always to guide the patient to the 00:47:59.420 --> 00:48:01.800 best long -term outcome, whether that's with 00:48:01.800 --> 00:48:06.840 or without a scalpel. often long -term impact 00:48:06.840 --> 00:48:09.840 of seemingly simple injuries and highlights the 00:48:09.840 --> 00:48:12.539 absolute imperative for comprehensive, diligent, 00:48:12.840 --> 00:48:15.960 and patient -centered care. Prof. Moimam, you've 00:48:15.960 --> 00:48:18.260 guided us through an incredibly detailed and 00:48:18.260 --> 00:48:21.139 remarkably insightful deep dive into ankle sprains. 00:48:21.440 --> 00:48:23.460 From the foundational anatomical understanding 00:48:23.460 --> 00:48:26.840 and nuanced classification through to the comprehensive 00:48:26.840 --> 00:48:29.360 treatment strategies and crucially, those vital 00:48:29.360 --> 00:48:32.500 prevention methods, you've provided an invaluable 00:48:32.500 --> 00:48:35.610 actionable overview for all of us as mid -senior 00:48:35.610 --> 00:48:38.010 medical professionals. What really stands out 00:48:38.010 --> 00:48:40.630 from our conversation today is the absolute importance 00:48:40.630 --> 00:48:42.809 of a thorough clinical approach right from the 00:48:42.809 --> 00:48:45.510 outset, meticulously ruling out those missed 00:48:45.510 --> 00:48:47.690 injuries, coupled with an unwavering commitment 00:48:47.690 --> 00:48:50.230 to comprehensive and often prolonged rehabilitation. 00:48:50.929 --> 00:48:53.610 These elements are unequivocally key to mitigating 00:48:53.610 --> 00:48:55.570 those potential long -term complications we've 00:48:55.570 --> 00:48:57.449 discussed, ensuring our patients don't get caught 00:48:57.449 --> 00:48:59.510 in that frustrating cycle of chronic pain and 00:48:59.510 --> 00:49:02.010 instability. We genuinely hope this deep dive 00:49:02.010 --> 00:49:03.789 has offered you some new perspectives, perhaps 00:49:03.789 --> 00:49:06.159 at clarified some complex areas or reinforced 00:49:06.159 --> 00:49:08.000 critical best practices in your own clinical 00:49:08.000 --> 00:49:10.639 encounters. If you found this deep dive valuable, 00:49:11.059 --> 00:49:12.860 please consider rating and sharing it with your 00:49:12.860 --> 00:49:15.059 colleagues. It truly helps us reach more professionals 00:49:15.059 --> 00:49:17.599 like you. My pleasure entirely. To leave you 00:49:17.599 --> 00:49:21.300 with a final thought. While ankle sprains are 00:49:21.300 --> 00:49:23.760 indeed ubiquitous and almost daily occurrence 00:49:23.760 --> 00:49:26.659 in our clinics, our continually evolving understanding 00:49:26.659 --> 00:49:29.840 of ankle biomechanics, the sophisticated rehabilitation 00:49:29.840 --> 00:49:32.719 principles we now have at our disposal, and the 00:49:32.719 --> 00:49:34.820 advanced surgical techniques available offer 00:49:34.820 --> 00:49:38.159 us genuinely significant opportunities. The true 00:49:38.159 --> 00:49:40.380 challenge for us as orthopedic professionals 00:49:40.380 --> 00:49:42.599 lies not just in knowing these advancements, 00:49:42.780 --> 00:49:45.300 but in the consistent, meticulous, and diligent 00:49:45.300 --> 00:49:47.639 application of these principles in every single 00:49:47.639 --> 00:49:49.679 clinical encounter. Because ultimately, this 00:49:49.679 --> 00:49:51.380 isn't just about treating an injury, it's about 00:49:51.380 --> 00:49:53.519 fundamentally preventing debilitating long -term 00:49:53.519 --> 00:49:56.340 consequences, and more broadly, significantly 00:49:56.340 --> 00:49:58.380 enhancing our patient's overall quality of life.
