00:00:00.000 --> 00:00:03.120
Welcome to the deep dive. You know, the shoulder

00:00:03.120 --> 00:00:06.200
is this incredible piece of biological engineering,

00:00:06.780 --> 00:00:09.720
just the most mobile joint in the human body.

00:00:09.820 --> 00:00:12.300
It really is amazing. Today we're going to unpack

00:00:12.300 --> 00:00:14.380
how specialists are using these cutting edge

00:00:14.380 --> 00:00:17.600
techniques, arthroscopy and endoscopy to, well,

00:00:18.359 --> 00:00:20.980
understand and fix its many quirks and injuries.

00:00:21.399 --> 00:00:24.300
We've got a fantastic, really in -depth textbook

00:00:24.300 --> 00:00:27.000
as our source. And our goal is basically to pull

00:00:27.000 --> 00:00:29.199
out the most useful and fascinating insights

00:00:29.199 --> 00:00:31.699
into how these minimally invasive procedures

00:00:31.699 --> 00:00:35.090
are actually done. That's right. What's remarkable

00:00:35.090 --> 00:00:37.429
about this field is just the sheer scope of what

00:00:37.429 --> 00:00:40.270
can now be addressed without those large incisions.

00:00:40.450 --> 00:00:43.429
This textbook really lays out everything from,

00:00:43.429 --> 00:00:45.090
you know, the basic anatomy, you need to get

00:00:45.090 --> 00:00:47.750
your head around to the really advanced surgical

00:00:47.750 --> 00:00:50.189
solutions for all sorts of shoulder problems

00:00:50.189 --> 00:00:53.130
like rotator cuff tears, instability, a whole

00:00:53.130 --> 00:00:55.170
gamut. Yeah. And it's not just about what's possible

00:00:55.170 --> 00:00:57.570
now. The author's enthusiasm for the future of

00:00:57.570 --> 00:00:59.929
shoulder surgery is, well, it's pretty infectious.

00:01:00.229 --> 00:01:02.710
He genuinely believes the field is advancing

00:01:02.710 --> 00:01:06.319
so rapidly. that this entire book might need

00:01:06.319 --> 00:01:09.560
a complete overhaul within the next decade. That

00:01:09.560 --> 00:01:11.780
gives you a real sense of how much innovation

00:01:11.780 --> 00:01:13.599
is happening, doesn't it? It certainly does.

00:01:13.620 --> 00:01:16.640
It's moving fast. Okay, let's unpack this. We

00:01:16.640 --> 00:01:18.739
can't really talk about fixing the shoulder without

00:01:18.739 --> 00:01:20.799
understanding what makes it tick. Absolutely

00:01:20.799 --> 00:01:23.560
fundamental. Let's start with the arthroscopic

00:01:23.560 --> 00:01:26.680
anatomy, this incredibly mobile glenohumeral

00:01:26.680 --> 00:01:29.340
joint that's where your upper arm bone meets

00:01:29.340 --> 00:01:31.819
your shoulder blade. How does it manage to be

00:01:31.819 --> 00:01:37.010
so flexible yet stay stable. It's a clever combination

00:01:37.010 --> 00:01:39.629
of what we call passive and active stabilizers.

00:01:39.930 --> 00:01:42.769
So think of the passive structures as the underlying

00:01:42.769 --> 00:01:44.909
framework. Okay. You've got the glenoid, which

00:01:44.909 --> 00:01:46.810
is the shallow socket on your shoulder blade,

00:01:47.310 --> 00:01:49.689
the head of the humerus, the ball of your arm

00:01:49.689 --> 00:01:52.549
bone fitting into that socket, the labrum. That

00:01:52.549 --> 00:01:54.750
cartilage ring? Exactly, that cartilage ring

00:01:54.750 --> 00:01:57.230
around the glenoid that deepens the socket. Then

00:01:57.230 --> 00:01:59.310
there's the joint capsule, the fibrous tissue

00:01:59.310 --> 00:02:01.730
enclosing the whole joint, and the ligaments,

00:02:01.870 --> 00:02:04.189
those tough bands connecting bone to bone. So

00:02:04.189 --> 00:02:06.269
that's the static support, the framework. Now

00:02:06.269 --> 00:02:09.069
for the active part, the muscles. Exactly. These

00:02:09.069 --> 00:02:11.270
are the dynamic controllers, allowing for movement

00:02:11.270 --> 00:02:14.030
and providing crucial stability. The rotator

00:02:14.030 --> 00:02:16.990
cuff muscles, supraspinatus, infraspinatus, teres

00:02:16.990 --> 00:02:19.849
minor, and substabularis are key players here,

00:02:20.030 --> 00:02:22.669
along with the long head of the biceps, the deltoid,

00:02:22.750 --> 00:02:24.990
the big muscle on the outside of your shoulder,

00:02:25.169 --> 00:02:27.789
and all the muscles that control how your scapula,

00:02:27.830 --> 00:02:30.990
your shoulder blade moves. It's this coordinated

00:02:30.990 --> 00:02:33.930
muscle action that allows you to reach for things,

00:02:34.030 --> 00:02:36.710
throw a ball, everything in between, all while

00:02:36.710 --> 00:02:39.060
keeping the joint secure. Now here's a detail

00:02:39.060 --> 00:02:41.340
that apparently surprises even some experienced

00:02:41.340 --> 00:02:44.919
surgeons, telling the supraspinatus and infraspinatus

00:02:44.919 --> 00:02:47.979
muscles apart during an arthroscopic procedure.

00:02:49.610 --> 00:02:52.349
It can be tricky. It really can be. One helpful

00:02:52.349 --> 00:02:54.710
landmark is often a subtle contour line that

00:02:54.710 --> 00:02:56.849
naturally separates the two muscles. Ah, okay.

00:02:57.009 --> 00:02:59.729
Also, if we see cysts or bony spurs, what we

00:02:59.729 --> 00:03:02.830
call osteophytes, around the greater cuporosity,

00:03:03.069 --> 00:03:04.689
that's that bony bump on the outside of your

00:03:04.689 --> 00:03:07.009
upper arm bone, it can suggest long -standing

00:03:07.009 --> 00:03:09.969
subacromial impingement. Impingement. That's

00:03:09.969 --> 00:03:12.090
the narrowing of this space. Right. A narrowing

00:03:12.090 --> 00:03:14.969
of the space above the rotator cuff. And this

00:03:14.969 --> 00:03:17.650
can sometimes give us an indirect clue about

00:03:17.650 --> 00:03:19.870
potential issues with the underlying rotator

00:03:19.870 --> 00:03:23.009
cuff muscles themselves. OK. So once we have

00:03:23.009 --> 00:03:26.370
a sense of the anatomy, how do we actually get

00:03:26.370 --> 00:03:29.310
a look inside a living shoulder? Radiological

00:03:29.310 --> 00:03:31.330
investigations are obviously crucial. And it

00:03:31.330 --> 00:03:33.610
sounds like good old x -rays are still the starting

00:03:33.610 --> 00:03:36.189
point. Absolutely. X -rays are fantastic for

00:03:36.189 --> 00:03:38.389
that initial overview, especially for identifying

00:03:38.389 --> 00:03:41.550
things like dislocations and fractures. Different

00:03:41.550 --> 00:03:44.169
views let us see the bones from various angles,

00:03:44.229 --> 00:03:46.949
which is key for diagnosing specific problems.

00:03:47.069 --> 00:03:50.810
Makes sense. For example, the standard AP, anteroposterior,

00:03:50.969 --> 00:03:54.129
scapular Y, and axillary views are pretty essential

00:03:54.129 --> 00:03:57.449
for evaluating acute shoulder dislocations. Then

00:03:57.449 --> 00:03:59.629
you have specialized views like the West Point

00:03:59.629 --> 00:04:02.330
and striker notch views. These are particularly

00:04:02.330 --> 00:04:04.500
helpful for visualizing fractures on the front

00:04:04.500 --> 00:04:07.659
of the glenoid socket or those hill -sax lesions.

00:04:07.680 --> 00:04:10.080
Those little dents on the humeral head from dislocation.

00:04:10.240 --> 00:04:12.280
Exactly those, the ones that can happen when

00:04:12.280 --> 00:04:14.900
the shoulder dislocates forward. And when we

00:04:14.900 --> 00:04:17.259
need to really see the soft tissues of muscles,

00:04:17.519 --> 00:04:20.839
tendons, ligaments, that's where MRI and MRA

00:04:20.839 --> 00:04:22.500
come in, right? What's the difference there?

00:04:22.819 --> 00:04:25.680
So MRI, magnetic resonance imaging, gives us

00:04:25.680 --> 00:04:27.660
incredibly detailed pictures of all the soft

00:04:27.660 --> 00:04:30.649
tissue structures. MRA or MR arthrogram takes

00:04:30.649 --> 00:04:33.290
it a step further. How so? By injecting a contrast

00:04:33.290 --> 00:04:35.949
dye directly into the joint before the MRI scan.

00:04:36.730 --> 00:04:39.189
This contrast really highlights the outlines

00:04:39.189 --> 00:04:41.550
of structures like the labrum and ligaments,

00:04:41.949 --> 00:04:44.910
making tears much easier to spot. Clever. For

00:04:44.910 --> 00:04:47.269
instance, putting the arm in a specific position

00:04:47.269 --> 00:04:50.610
called ABER, that's abduction and external rotation

00:04:50.610 --> 00:04:53.370
during an MRA, can significantly improve our

00:04:53.370 --> 00:04:56.029
ability to detect tears in the antero -inferior

00:04:56.029 --> 00:04:58.230
labrum, the front and bottom part of that cartilage.

00:04:58.250 --> 00:05:01.170
I see. This can help us identify specific types

00:05:01.170 --> 00:05:04.089
of injuries, like ALPSA lesions. What are those

00:05:04.089 --> 00:05:05.949
again? That's where the torn labrum isn't just

00:05:05.949 --> 00:05:08.170
torn, but it also gets pushed and kind of rolled

00:05:08.170 --> 00:05:10.529
onto the neck of the scapula. Yeah. MRI also

00:05:10.529 --> 00:05:13.009
helps see ruptures of the inferior glenohumeral

00:05:13.009 --> 00:05:16.310
ligament, or IGHL, the key stabilizer. Got it.

00:05:16.649 --> 00:05:18.709
Now CT orthography is another imaging technique

00:05:18.709 --> 00:05:21.730
mentioned. Where does that fit in? CT arthrography,

00:05:21.810 --> 00:05:24.709
which combines a CT scan with that contrast injection

00:05:24.709 --> 00:05:27.209
into the joint, is really good for seeing the

00:05:27.209 --> 00:05:29.750
bony architecture in great detail. OK, so more

00:05:29.750 --> 00:05:33.449
for bone. Primarily, yes. It's particularly useful

00:05:33.449 --> 00:05:35.589
for assessing the amount of bone loss in the

00:05:35.589 --> 00:05:37.870
glenoid socket, which is crucial information

00:05:37.870 --> 00:05:41.009
in cases of recurrent instability. However, it's

00:05:41.009 --> 00:05:44.610
generally not as sensitive as a direct MRA for

00:05:44.610 --> 00:05:47.709
picking up small, non -displaced tears in the

00:05:47.709 --> 00:05:51.560
labrum. these MRI scans isn't always black and

00:05:51.560 --> 00:05:53.839
white, is it? I read there are anatomical variations

00:05:53.839 --> 00:05:56.160
that can sometimes look like tears. That's a

00:05:56.160 --> 00:05:58.240
really important point, especially in the antero

00:05:58.240 --> 00:06:00.300
-superior part of the labrum, roughly the top

00:06:00.300 --> 00:06:02.759
and front of the socket. There are a few common

00:06:02.759 --> 00:06:05.379
anatomical variations that can sometimes be mistaken

00:06:05.379 --> 00:06:09.139
for SLAPs. SLAP tears. Superior labrum tears.

00:06:09.259 --> 00:06:12.019
Right, tears of the superior labrum. These variations

00:06:12.019 --> 00:06:14.339
include the Buford complex. Okay, Buford complex.

00:06:14.439 --> 00:06:16.819
That's where a portion of the antero -superior

00:06:16.819 --> 00:06:19.819
labrum is missing, and the middle glenohumeral

00:06:19.819 --> 00:06:21.959
ligament is thickened and sort of cord -like.

00:06:22.459 --> 00:06:25.240
We also see things like a sublaboral sulcus,

00:06:25.360 --> 00:06:28.279
which is a small groove beneath the labrum, and

00:06:28.279 --> 00:06:31.100
a sublaboral foramen, a small hole in the labrum.

00:06:31.319 --> 00:06:33.240
That Buford complex sounds interesting. What's

00:06:33.240 --> 00:06:36.160
the key thing for surgeons and maybe patients

00:06:36.160 --> 00:06:38.860
to know about it? Well, the key thing is recognizing

00:06:38.860 --> 00:06:41.899
it as a normal variation so you don't mistakenly

00:06:41.899 --> 00:06:44.620
diagnose a labral tear that isn't actually there.

00:06:44.740 --> 00:06:47.040
Right. Avoid unnecessary treatment. Exactly.

00:06:47.769 --> 00:06:49.990
Interestingly, though, some recent research suggests

00:06:49.990 --> 00:06:52.529
that this specific anatomical setup, the Buford

00:06:52.529 --> 00:06:55.350
complex, might actually make individuals a bit

00:06:55.350 --> 00:06:57.850
more prone to developing SLAP lesions later on,

00:06:57.850 --> 00:07:00.649
perhaps due to altered biomechanics in the shoulder.

00:07:00.990 --> 00:07:04.310
Okay. Beyond the soft tissues, the shape of the

00:07:04.310 --> 00:07:06.310
acromion, that bony prominence on the top of

00:07:06.310 --> 00:07:08.110
your shoulder blade, that can also play a role

00:07:08.110 --> 00:07:10.709
in shoulder problems, can't it? Absolutely. We

00:07:10.709 --> 00:07:12.709
classify the shape of the acromion into three

00:07:12.709 --> 00:07:14.750
types, based on what it looks like from underneath

00:07:14.750 --> 00:07:19.209
on a specific x -ray view. 3 -type. Yep. Type

00:07:19.209 --> 00:07:22.029
1 is essentially flat, type 2 has a gentle curve,

00:07:22.170 --> 00:07:25.230
and type 3 is also curved, but with a hook -like

00:07:25.230 --> 00:07:27.649
projection pointing downward. Ah, the hooked

00:07:27.649 --> 00:07:30.750
one. Right. It's this type 3 acromeon that has

00:07:30.750 --> 00:07:33.449
the strongest link to subacromial impingement,

00:07:33.610 --> 00:07:35.949
that compression of the rotator cuff tendons,

00:07:36.230 --> 00:07:39.329
and consequently rotator cuff tears. The hook

00:07:39.329 --> 00:07:41.689
shape basically narrows the space where the tendons

00:07:41.689 --> 00:07:44.189
have to glide. And there's also the acromial

00:07:44.189 --> 00:07:46.170
index, a measurement we can take on x -rays.

00:07:46.519 --> 00:07:49.220
What does that tell us? The acromial index or

00:07:49.220 --> 00:07:52.980
AI is a ratio. It compares two distances measured

00:07:52.980 --> 00:07:55.600
on a frontal x -ray of the shoulder. It's the

00:07:55.600 --> 00:07:57.500
distance from the edge of the glenoid socket

00:07:57.500 --> 00:08:00.000
to the outer edge of the acromion, divided by

00:08:00.000 --> 00:08:01.819
the distance from the glenoid to the outer edge

00:08:01.819 --> 00:08:04.259
of the greater tuberosity. So a bigger number

00:08:04.259 --> 00:08:06.800
means the acromion sticks out more. Exactly.

00:08:07.199 --> 00:08:09.540
A higher AI value means the acromion extends

00:08:09.540 --> 00:08:12.339
further laterally, or sideways. Studies have

00:08:12.339 --> 00:08:14.459
shown that people with a higher acromial index

00:08:14.459 --> 00:08:17.300
are more likely to experience subacromial impingement

00:08:17.300 --> 00:08:19.939
and have rotator cuff problems. Interesting correlation.

00:08:20.360 --> 00:08:22.160
For example, people who don't have any shoulder

00:08:22.160 --> 00:08:24.819
issues tend to have a lower AI while those with

00:08:24.819 --> 00:08:27.579
significant rotator cuff tears often have a higher

00:08:27.579 --> 00:08:30.360
AI. It just gives us another piece of the puzzle

00:08:30.360 --> 00:08:33.279
when evaluating shoulder pain. Let's switch gears

00:08:33.279 --> 00:08:35.720
a bit and talk about the biceps tendon. It's

00:08:35.720 --> 00:08:38.039
not just about flexing your arm. It plays a role

00:08:38.039 --> 00:08:40.659
in shoulder stability too, doesn't it? It absolutely

00:08:40.659 --> 00:08:43.919
does. The long head of the biceps tendon, or

00:08:43.919 --> 00:08:46.879
LHBT, is held in its groove at the front of the

00:08:46.879 --> 00:08:49.419
upper arm bone by a really important structure

00:08:49.419 --> 00:08:52.279
called the biceps pulley, sometimes also called

00:08:52.279 --> 00:08:54.759
the biceps sling. The pulley. Yeah, this pulley

00:08:54.759 --> 00:08:57.259
is a complex of ligaments and tendon fibers.

00:08:57.480 --> 00:09:00.620
It's primarily made up of the superior glenohumeral

00:09:00.620 --> 00:09:03.740
ligament, the coracohumeral ligament, and also

00:09:03.740 --> 00:09:06.480
fibers from the subscapularis tendon as it wraps

00:09:06.480 --> 00:09:09.100
around the front of the shoulder. OK. Interestingly,

00:09:09.129 --> 00:09:11.409
the transverse humeral ligament, which you might

00:09:11.409 --> 00:09:13.889
have heard of as holding the biceps tendon in

00:09:13.889 --> 00:09:16.669
place, is now understood to be largely composed

00:09:16.669 --> 00:09:20.149
of fibers coming from the subscapularis and supraspinatus

00:09:20.149 --> 00:09:22.149
tendons. Ah, so it's more connected than we thought.

00:09:22.690 --> 00:09:25.309
Right. And because this whole biceps pulley sits

00:09:25.309 --> 00:09:28.110
within the rotator interval, that gap between

00:09:28.110 --> 00:09:31.129
the supraspinatus and subscapularis tendons injuries

00:09:31.129 --> 00:09:34.029
in this area often involve the pulley as well.

00:09:34.320 --> 00:09:36.919
How do you spot those pulley injuries? Ultrasound

00:09:36.919 --> 00:09:38.940
can be a really useful tool here. It can actually

00:09:38.940 --> 00:09:42.080
let us see injuries to the ligaments that make

00:09:42.080 --> 00:09:44.980
up the biceps pulley, like the SGHL and CHL,

00:09:45.179 --> 00:09:47.460
and detect if the biceps tendon is slipping out

00:09:47.460 --> 00:09:50.039
of its normal position, which we call subluxation.

00:09:50.340 --> 00:09:52.500
Another common and often frustrating shoulder

00:09:52.500 --> 00:09:55.360
issue is adhesive capsulitis or frozen shoulder.

00:09:55.860 --> 00:09:58.259
How can imaging help with that diagnosis? Well,

00:09:58.320 --> 00:10:00.519
the diagnosis of adhesive capsulitis is mainly

00:10:00.519 --> 00:10:03.080
based on a patient's symptoms and a physical

00:10:03.080 --> 00:10:05.250
exam show showing that restricted movement. Right,

00:10:05.429 --> 00:10:08.470
the classic stiffness. Exactly. But MRI can be

00:10:08.470 --> 00:10:11.330
helpful as an additional tool, primarily to rule

00:10:11.330 --> 00:10:13.649
out other conditions that might be causing similar

00:10:13.649 --> 00:10:16.110
pain and stiffness. So ruling things out. Mostly.

00:10:16.549 --> 00:10:18.649
In some cases of adhesive capsulitis, though,

00:10:18.789 --> 00:10:21.350
an MRI might show a thickening of the joint capsule

00:10:21.350 --> 00:10:23.450
itself and sometimes even a small amount of fluid

00:10:23.450 --> 00:10:25.850
within the joint. But it's not always definitive

00:10:25.850 --> 00:10:28.139
just from the scan. Finally, for this section,

00:10:28.299 --> 00:10:30.679
let's touch on the acromioclavicular joint, the

00:10:30.679 --> 00:10:33.659
AC joint, where your collarbone meets the acromion.

00:10:34.419 --> 00:10:35.899
Osteoarthritis is quite common there, isn't it?

00:10:36.009 --> 00:10:39.110
It is. Achromioclavicular joint osteoarthritis,

00:10:39.289 --> 00:10:42.649
or ACJOA, can develop as a result of a direct

00:10:42.649 --> 00:10:45.210
injury to the AC joint, like a fall onto the

00:10:45.210 --> 00:10:47.470
shoulder. It's also frequently seen in people

00:10:47.470 --> 00:10:50.789
who have subachromial impingement. OK. On imaging,

00:10:51.090 --> 00:10:53.110
we might see signs of wear and tear in the joint,

00:10:53.169 --> 00:10:55.970
like the cartilage thinning, bone spurs forming

00:10:55.970 --> 00:10:58.370
those osteophytes again, and sometimes even small

00:10:58.370 --> 00:11:01.049
cysts in the bone just below the cartilage. And

00:11:01.049 --> 00:11:03.610
distinguishing old injuries from arthritis. Yeah.

00:11:03.629 --> 00:11:05.929
Early signs of ACJ degeneration. can sometimes

00:11:05.929 --> 00:11:08.470
be hard to tell apart from old, minor sprains

00:11:08.470 --> 00:11:11.110
of the AC joint, as both can show some thickening

00:11:11.110 --> 00:11:13.789
of the joint capsule. If we also see involvement

00:11:13.789 --> 00:11:16.269
of the coracoclavicular ligaments, the ones holding

00:11:16.269 --> 00:11:18.889
the clavicle down, that often suggests a more

00:11:18.889 --> 00:11:21.690
significant past injury to the AC joint. Okay,

00:11:21.710 --> 00:11:23.789
we've covered a lot of ground on anatomy and

00:11:23.789 --> 00:11:26.909
diagnosis. Let's move into treatment. Arthroscopic

00:11:26.909 --> 00:11:29.190
surgery relies heavily on the use of cannulas.

00:11:29.789 --> 00:11:31.629
What are they and why are they so important?

00:11:31.799 --> 00:11:35.019
Okay, so think of cannulas as little access tunnels

00:11:35.019 --> 00:11:37.360
into the shoulder joint. They're hollow tubes

00:11:37.360 --> 00:11:39.960
that we ensuit through small incisions. Got it.

00:11:39.980 --> 00:11:42.779
Tunnels. And they're absolutely essential for

00:11:42.779 --> 00:11:45.799
making arthroscopic surgery efficient. They allow

00:11:45.799 --> 00:11:48.279
us to easily swap different surgical instruments

00:11:48.279 --> 00:11:51.279
in and out as needed without having to make multiple

00:11:51.279 --> 00:11:53.840
large incisions or constantly repuncture the

00:11:53.840 --> 00:11:56.779
skin. Makes sense. They're also crucial for managing

00:11:56.779 --> 00:11:59.139
sutures during the procedure, preventing them

00:11:59.139 --> 00:12:01.620
from getting tangled or catching on other tissues?

00:12:01.820 --> 00:12:04.240
What kinds are there? Cannulas come in various

00:12:04.240 --> 00:12:07.379
sizes, lengths, and materials. You have soft

00:12:07.379 --> 00:12:10.320
silicone cannulas, which are less bulky and can

00:12:10.320 --> 00:12:12.779
even help with gently retracting tissues inside

00:12:12.779 --> 00:12:15.159
the joint, but you have to be careful with sharp

00:12:15.159 --> 00:12:17.440
instruments around them. Right. Then there are

00:12:17.440 --> 00:12:20.559
hard cannulas, more resistant to accidental puncture,

00:12:20.580 --> 00:12:22.679
but sometimes less maneuverable, especially if

00:12:22.679 --> 00:12:24.700
you're using several at once. Any downsides?

00:12:25.200 --> 00:12:27.740
Well, one important thing to watch out for is

00:12:27.740 --> 00:12:30.980
fluid extravasation. If a cannula accidentally

00:12:30.980 --> 00:12:33.720
slips out of the joint during surgery, the fluid

00:12:33.720 --> 00:12:36.179
we use to inflate the joint can leak out into

00:12:36.179 --> 00:12:38.940
the surrounding soft tissues. Ah, okay. Needs

00:12:38.940 --> 00:12:42.059
careful management. Now arthroscopic fixation

00:12:42.059 --> 00:12:44.779
of bony bankart lesions, that's when a piece

00:12:44.779 --> 00:12:47.100
of bone breaks off the front of the glenoid during

00:12:47.100 --> 00:12:49.460
a shoulder dislocation. That seems like a key

00:12:49.460 --> 00:12:51.259
area where these techniques have really made

00:12:51.259 --> 00:12:54.169
a difference. They absolutely have. For smaller

00:12:54.169 --> 00:12:56.570
bony bankart lesions, what we sometimes call

00:12:56.570 --> 00:12:59.950
bigliani type I or II, where the bone fragment

00:12:59.950 --> 00:13:02.450
is still in relatively good shape and hasn't

00:13:02.450 --> 00:13:06.029
shifted too much, arthroscopic reduction, basically

00:13:06.029 --> 00:13:08.750
putting the bone back in place and internal fixation

00:13:08.750 --> 00:13:11.230
holding it there with anchors and sutures is

00:13:11.230 --> 00:13:14.289
often the preferred approach. The goal is to

00:13:14.289 --> 00:13:17.529
restore that smooth, continuous surface of the

00:13:17.529 --> 00:13:19.700
glenoid socket. But there's a limit. Right, if

00:13:19.700 --> 00:13:22.759
the bone loss is too big. Exactly. If the glenoid

00:13:22.759 --> 00:13:25.659
defect is larger than about 20 to 25 percent

00:13:25.659 --> 00:13:27.960
of the socket surface area, that's generally

00:13:27.960 --> 00:13:30.659
considered a critical size. Okay. In these cases,

00:13:30.860 --> 00:13:32.860
arthroscopic repair alone might not be enough

00:13:32.860 --> 00:13:35.620
to prevent future dislocations, and other procedures

00:13:35.620 --> 00:13:38.679
like the latarjet or bone grafting might be necessary

00:13:38.679 --> 00:13:40.740
to rebuild the socket. And techniques for fixing

00:13:40.740 --> 00:13:43.700
those fragments arthroscopically. Surgeons often

00:13:43.700 --> 00:13:46.320
use specific techniques, like the double pulley

00:13:46.320 --> 00:13:49.440
technique, to get a really secure hold on those

00:13:49.440 --> 00:13:51.879
bony fragments during the arthroscopic repair.

00:13:52.259 --> 00:13:54.620
What about the success rates of these arthroscopic

00:13:54.620 --> 00:13:56.759
band cart repairs? Does it matter if the shoulder

00:13:56.759 --> 00:14:00.559
has been dislocating for a while versus a first

00:14:00.559 --> 00:14:03.909
-time dislocation? That's a good question. The

00:14:03.909 --> 00:14:06.669
research suggests that arthroscopic banker repairs

00:14:06.669 --> 00:14:09.230
tend to have better outcomes when performed after

00:14:09.230 --> 00:14:12.789
an acute or first -time dislocation compared

00:14:12.789 --> 00:14:16.049
to chronic recurrent instability. Why is that?

00:14:16.549 --> 00:14:18.529
Well, studies have shown that many patients with

00:14:18.529 --> 00:14:21.230
acute glenoid rim fractures can regain stability

00:14:21.230 --> 00:14:23.509
and get back to their previous activities after

00:14:23.509 --> 00:14:25.750
a single row of anchors is used to fix the bone

00:14:25.750 --> 00:14:28.350
and labrum. But the results for chronic cases

00:14:28.350 --> 00:14:30.710
treated with the same single row technique have

00:14:30.710 --> 00:14:33.409
sometimes been less predictable. It's possible

00:14:33.409 --> 00:14:35.590
the bone and ligaments can change over time with

00:14:35.590 --> 00:14:37.870
repeated dislocations, making them harder to

00:14:37.870 --> 00:14:39.570
repair effectively. But it's not always clear

00:14:39.570 --> 00:14:42.269
cut. No, interestingly, some studies have reported

00:14:42.269 --> 00:14:45.070
good success even in chronic cases where the

00:14:45.070 --> 00:14:47.690
bone fragments are still well -preserved. And

00:14:47.690 --> 00:14:50.470
more recently, techniques using two rows of anchors,

00:14:50.710 --> 00:14:53.710
so -called double -row repair, have shown promising

00:14:53.710 --> 00:14:56.429
results for both acute and chronic instability.

00:14:56.629 --> 00:15:00.610
Double row. More anchors, better fixation. Potentially,

00:15:00.889 --> 00:15:03.929
yes. It creates a wider area of contact. Patients

00:15:03.929 --> 00:15:05.929
report good satisfaction and improvements in

00:15:05.929 --> 00:15:08.980
how the shoulder feels and functions, but Ultimately,

00:15:09.220 --> 00:15:11.559
a really important factor in the success of any

00:15:11.559 --> 00:15:14.700
bank art repair seems to be making sure the reconstructed

00:15:14.700 --> 00:15:17.659
glenoid socket is at least 80 % of its original

00:15:17.659 --> 00:15:19.899
size. That makes sense, restoring the anatomy.

00:15:20.379 --> 00:15:22.679
Now for shoulder instability in general, surgery

00:15:22.679 --> 00:15:24.779
isn't always the first thing doctors recommend,

00:15:24.960 --> 00:15:27.059
is it? That's correct. Non -operative treatment

00:15:27.059 --> 00:15:29.220
is often the first step. This usually involves

00:15:29.220 --> 00:15:31.620
wearing a sling for a few weeks to let the initial

00:15:31.620 --> 00:15:34.519
injury calm down, followed by a structured rehabilitation

00:15:34.519 --> 00:15:37.789
program. Physical therapy. Exactly. The rehab

00:15:37.789 --> 00:15:39.730
focuses on strengthening the muscles around the

00:15:39.730 --> 00:15:42.490
shoulder, especially the rotator cuff, and gradually

00:15:42.490 --> 00:15:45.009
restoring the full range of motion. But when

00:15:45.009 --> 00:15:47.899
is surgery indicated? Surgery might be recommended

00:15:47.899 --> 00:15:50.320
if the patient continues to experience symptoms

00:15:50.320 --> 00:15:52.740
like feeling the shoulder wants to slip out of

00:15:52.740 --> 00:15:55.940
place. That's a positive apprehension sign. Or

00:15:55.940 --> 00:15:58.200
if a doctor can physically put the shoulder back

00:15:58.200 --> 00:16:00.460
in place during an exam, which is a positive

00:16:00.460 --> 00:16:04.100
relocation sign. OK. Also, if certain exam maneuvers

00:16:04.100 --> 00:16:06.600
like the augmentation test or lag sign are positive

00:16:06.600 --> 00:16:09.419
or simply if conservative treatment doesn't provide

00:16:09.419 --> 00:16:11.980
enough relief and the shoulder continues to be

00:16:11.980 --> 00:16:14.200
unstable and really limits their function. Right.

00:16:14.639 --> 00:16:16.669
Let's move on to some specific shoulder conditions

00:16:16.669 --> 00:16:19.809
and their surgical management. The Letarget procedure

00:16:19.809 --> 00:16:22.350
is a well -known option for people with shoulder

00:16:22.350 --> 00:16:26.480
instability and significant bone loss. Can that

00:16:26.480 --> 00:16:30.220
be done arthroscopically? Yes, it can. The traditional

00:16:30.220 --> 00:16:33.039
latarjet procedure, which involves taking a piece

00:16:33.039 --> 00:16:35.320
of bone called the coracoid process from the

00:16:35.320 --> 00:16:37.360
front of the shoulder blade and transferring

00:16:37.360 --> 00:16:40.000
it to the front of the glenoid to act as a bony

00:16:40.000 --> 00:16:42.179
block. Right, the bone block. That's been performed

00:16:42.179 --> 00:16:44.700
as an open surgery for a long time and has a

00:16:44.700 --> 00:16:47.120
good track record for stabilizing the shoulder.

00:16:47.389 --> 00:16:50.970
But since about 2003, surgeons have also been

00:16:50.970 --> 00:16:53.470
performing the latarjet procedure arthroscopically

00:16:53.470 --> 00:16:56.429
using smaller incisions. What are the trade -off?

00:16:57.049 --> 00:16:59.809
Well, the arthroscopic approach can offer potential

00:16:59.809 --> 00:17:03.190
benefits like less pain and maybe quicker recovery,

00:17:03.529 --> 00:17:07.349
but both the open and arthroscopic letarget procedures

00:17:07.349 --> 00:17:10.369
carry some risks. Such as? One potential complication

00:17:10.369 --> 00:17:12.609
is a fracture of the transferred coracord bone

00:17:12.609 --> 00:17:14.789
itself, which can happen in the first few months

00:17:14.789 --> 00:17:17.849
after surgery. There's also a risk of nerve injury

00:17:17.849 --> 00:17:20.130
because of the delicate dissection involved near

00:17:20.130 --> 00:17:22.829
important nerves. When the glenoid bone loss

00:17:22.829 --> 00:17:25.049
is quite substantial, are there other surgical

00:17:25.049 --> 00:17:28.789
options besides the Yes. For more significant

00:17:28.789 --> 00:17:30.950
glenoid bone loss, surgeons sometimes use what

00:17:30.950 --> 00:17:34.029
we call extra -anatomic procedures. These include

00:17:34.029 --> 00:17:36.210
the letarget -bristaux procedure, which is a

00:17:36.210 --> 00:17:38.710
variation of the letarget, or using a separate

00:17:38.710 --> 00:17:40.849
piece of bone, often from the iliac crest, your

00:17:40.849 --> 00:17:43.450
hip bone. Ah, a graft from the hip. Right. Using

00:17:43.450 --> 00:17:45.569
that as a bone block that's then fixed to the

00:17:45.569 --> 00:17:47.710
glenoid, usually with screws. But those have

00:17:47.710 --> 00:17:50.650
potential issues too. They can. Complications

00:17:50.650 --> 00:17:53.690
like the bone not healing properly. non -union,

00:17:54.170 --> 00:17:56.789
the bone graft being reabsorbed by the body over

00:17:56.789 --> 00:17:59.950
time, or problems with the screws or other hardware

00:17:59.950 --> 00:18:02.829
used to hold the bone in place can occur. So

00:18:02.829 --> 00:18:04.869
alternatives? Well, the arthroscopic j -bone

00:18:04.869 --> 00:18:07.569
grafting technique offers another approach. This

00:18:07.569 --> 00:18:10.349
involves taking a bone graft from the iliac crest,

00:18:10.670 --> 00:18:13.049
shaping it carefully to fit the glenoid defect,

00:18:13.069 --> 00:18:15.690
and then securing it arthroscopically. What's

00:18:15.690 --> 00:18:17.750
the advantage there? A key advantage is that

00:18:17.750 --> 00:18:20.799
it's arguably more anatomical. aiming to restore

00:18:20.799 --> 00:18:23.480
the natural shape of the glenoid. Plus, it doesn't

00:18:23.480 --> 00:18:26.160
leave behind permanent metal implants like screws.

00:18:26.380 --> 00:18:28.839
OK. There's also a technique mentioned called

00:18:28.839 --> 00:18:32.119
arthroscopic bone block with subscapularis augmentation,

00:18:32.359 --> 00:18:35.599
or ASA. What's that all about? The ASA procedure

00:18:35.599 --> 00:18:38.680
is a more complex arthroscopic technique. It's

00:18:38.680 --> 00:18:41.099
designed for cases of severe glenoid bone loss

00:18:41.099 --> 00:18:43.680
combined with a deficient capsule -laboral complex,

00:18:43.940 --> 00:18:45.980
meaning both the cartilida rim and the surrounding

00:18:45.980 --> 00:18:48.559
ligaments are significantly damaged. So a double

00:18:48.559 --> 00:18:51.799
whammy. Pretty much. It involves creating tunnels

00:18:51.799 --> 00:18:54.480
in the glenoid bone to precisely position and

00:18:54.480 --> 00:18:57.759
secure a bone block graft using strong button

00:18:57.759 --> 00:19:00.880
-like anchors. And the subscapularis part. Importantly,

00:19:01.099 --> 00:19:04.400
it also includes augmenting or reinforcing the

00:19:04.400 --> 00:19:07.160
subscapularis tendon, that key stabilizer on

00:19:07.160 --> 00:19:09.359
the front of the shoulder, often using a strong

00:19:09.359 --> 00:19:12.160
suture tape anchor. So it's bone block plus tendon

00:19:12.160 --> 00:19:14.819
reinforcement. Exactly. This combined approach

00:19:14.819 --> 00:19:17.759
has shown promise as a feasible and safe alternative

00:19:17.759 --> 00:19:20.200
to the traditional Letarjet procedure in these

00:19:20.200 --> 00:19:23.180
more challenging instability cases. In situations

00:19:23.180 --> 00:19:25.299
where the bone loss isn't quite critical, are

00:19:25.299 --> 00:19:27.460
there other types of grafts that might be considered

00:19:27.460 --> 00:19:30.630
like not from the hip? Yes. For glenohumeral

00:19:30.630 --> 00:19:32.930
instability with a smaller degree of bone loss,

00:19:33.250 --> 00:19:35.829
or in cases where a hill -sax lesion, that dent

00:19:35.829 --> 00:19:38.670
on the humeral head is off -track, meaning it's

00:19:38.670 --> 00:19:40.549
likely to engage with the glenoid rim during

00:19:40.549 --> 00:19:44.349
movement, an arthroscopic distal clavicle osteochondral

00:19:44.349 --> 00:19:46.650
autograft transfer might be an option. Taking

00:19:46.650 --> 00:19:49.569
bone from the collarbone. Right. This involves

00:19:49.569 --> 00:19:51.890
taking a small piece of bone and its overlying

00:19:51.890 --> 00:19:55.069
cartilage from the end of the clavicle and transplanting

00:19:55.069 --> 00:19:57.309
it to the glenoid defect. When wouldn't you use

00:19:57.309 --> 00:20:00.630
that? Well, this technique is generally not recommended

00:20:00.630 --> 00:20:03.289
for patients who have very loose joints overall,

00:20:03.750 --> 00:20:07.190
what we call global hyperlaxity, or if they have

00:20:07.190 --> 00:20:09.910
significant bone loss on the humeral head itself,

00:20:10.210 --> 00:20:12.390
or if they've had a previous resection of the

00:20:12.390 --> 00:20:15.650
end of the clavicle. Okay. What happens when

00:20:15.650 --> 00:20:19.289
a Letarjet procedure unfortunately doesn't achieve

00:20:19.289 --> 00:20:23.240
the desired stability? revision possible? Revision

00:20:23.240 --> 00:20:25.720
surgery after a failed lethargic procedure can

00:20:25.720 --> 00:20:28.119
be quite complex as you can imagine. Surgeons

00:20:28.119 --> 00:20:31.119
sometimes use a specific posterior portal, an

00:20:31.119 --> 00:20:32.720
entry point at the back of the shoulder called

00:20:32.720 --> 00:20:35.700
the Halifax portal. A specific portal? Yeah,

00:20:35.980 --> 00:20:38.619
this portal can provide better access and visualization

00:20:38.619 --> 00:20:41.200
of the surgical area during these tricky revision

00:20:41.200 --> 00:20:43.660
procedures, allowing for a more thorough assessment

00:20:43.660 --> 00:20:47.279
and repair. Now, hill -sax lesions, those indentations

00:20:47.279 --> 00:20:50.220
on the humeral head from dislocations, can also

00:20:50.220 --> 00:20:52.920
contribute to ongoing instability. The remplassage

00:20:52.920 --> 00:20:55.140
procedure is designed to address those. How does

00:20:55.140 --> 00:20:57.799
it work? The remplassage procedure aims to prevent

00:20:57.799 --> 00:21:00.119
a hill -sax lesion from catching or engaging

00:21:00.119 --> 00:21:02.640
on the edge of the glenoid socket during shoulder

00:21:02.640 --> 00:21:05.119
movement, which can cause further instability

00:21:05.119 --> 00:21:08.460
or pain. So how do you stop it catching? It involves

00:21:08.460 --> 00:21:11.160
essentially filling in the hillsack's defect

00:21:11.160 --> 00:21:14.039
with sock tissue, typically by using a portion

00:21:14.039 --> 00:21:16.279
of the infraspinatus tendon, one of the rotator

00:21:16.279 --> 00:21:18.799
cuff muscles, and anchoring it right into the

00:21:18.799 --> 00:21:20.940
bony defect on the humerus. Filling the dent.

00:21:21.140 --> 00:21:23.799
Basically, yes. This procedure is often considered

00:21:23.799 --> 00:21:26.099
in cases where there's an engaging hillsack's

00:21:26.099 --> 00:21:29.200
lesion, but less than 25 % of glenoid bone loss.

00:21:29.299 --> 00:21:32.380
It's often done alongside a bankart repair. HEGL

00:21:32.380 --> 00:21:35.039
lesions. That's when the inferior glenohumeral

00:21:35.039 --> 00:21:37.349
ligament tears away from its attachment. on the

00:21:37.349 --> 00:21:39.950
humerus, they also require specific attention,

00:21:39.970 --> 00:21:42.650
right? Yes, definitely. Arthroscopic repair of

00:21:42.650 --> 00:21:45.009
HAGL lesions where the ligament is reattached

00:21:45.009 --> 00:21:47.789
to the humerus using anchors is certainly possible

00:21:47.789 --> 00:21:49.890
and often effective. Is the recovery different

00:21:49.890 --> 00:21:52.369
depending on where the tear is? The post -operative

00:21:52.369 --> 00:21:56.000
care can differ slightly. For anterior inferior

00:21:56.000 --> 00:21:58.740
tears, on the front and bottom, immobilization

00:21:58.740 --> 00:22:02.279
in a standard sling is typical. For reverse HAGL

00:22:02.279 --> 00:22:05.160
tears on the backside, surgeons might use an

00:22:05.160 --> 00:22:07.440
external rotation brace or an abduction pillow

00:22:07.440 --> 00:22:10.019
to protect the repair, as these positions put

00:22:10.019 --> 00:22:12.359
less stress on the repaired posterior ligament.

00:22:12.960 --> 00:22:15.859
OK. Posterior shoulder instability, while less

00:22:15.859 --> 00:22:18.180
common than anterior instability, still poses

00:22:18.180 --> 00:22:20.720
challenges for diagnosis and treatment. It does.

00:22:21.240 --> 00:22:23.619
Arthroscopic assessment is really valuable in

00:22:23.619 --> 00:22:26.279
evaluating posterior shoulder instability to

00:22:26.279 --> 00:22:28.980
identify if there are any associated bone or

00:22:28.980 --> 00:22:31.259
soft tissue injuries, like a reverse bank heart

00:22:31.259 --> 00:22:35.039
lesion or posterior labral tear. Is surgery always

00:22:35.039 --> 00:22:37.720
the answer? No. Surgery is generally not recommended

00:22:37.720 --> 00:22:39.960
for patients who can voluntarily dislocate their

00:22:39.960 --> 00:22:42.599
shoulder or those who aren't likely to be cooperative

00:22:42.599 --> 00:22:44.980
or able to actively participate in the extensive

00:22:44.980 --> 00:22:47.519
rehabilitation process required afterwards. Right.

00:22:47.660 --> 00:22:50.259
In some chronic cases where pain is minimal and

00:22:50.259 --> 00:22:52.119
function is still reasonably good despite some

00:22:52.119 --> 00:22:54.799
laxity, non -operative management might actually

00:22:54.799 --> 00:22:57.900
be the preferred approach. Multidirectional instability,

00:22:58.339 --> 00:23:01.579
or MDI, is when the shoulder feels loose in multiple

00:23:01.579 --> 00:23:04.779
directions. How is that managed arthroscopically?

00:23:05.140 --> 00:23:07.720
MDI is a complex condition. It can be caused

00:23:07.720 --> 00:23:10.579
by a combination of factors, including naturally

00:23:10.579 --> 00:23:13.380
loose joints, congenital hyperlaxity. Born with

00:23:13.380 --> 00:23:16.470
loose joints? Sometimes, yes. or it can be due

00:23:16.470 --> 00:23:18.890
to repeated minor injuries like microtrauma,

00:23:19.150 --> 00:23:20.829
imbalances in the muscles around the shoulder,

00:23:21.329 --> 00:23:25.799
and certain anatomical predispositions. A key

00:23:25.799 --> 00:23:28.180
finding is often laxity in the coracor humeral

00:23:28.180 --> 00:23:30.920
ligament and an overly loose or redundant joint

00:23:30.920 --> 00:23:33.119
capsule, especially in the front and bottom parts

00:23:33.119 --> 00:23:35.480
of the joint. So how do you fix that looseness?

00:23:35.880 --> 00:23:38.619
Arthroscopic capsule replication, or ACP, is

00:23:38.619 --> 00:23:40.799
a surgical technique used to address this. It

00:23:40.799 --> 00:23:43.019
involves taking tucks or pleats in the joint

00:23:43.019 --> 00:23:45.319
capsule to effectively tighten it up and reduce

00:23:45.319 --> 00:23:47.900
the excessive laxity. These pleats are then secured

00:23:47.900 --> 00:23:50.559
with sutures or anchors. How does that compare

00:23:50.559 --> 00:23:53.710
to older open surgeries? Compared to older open

00:23:53.710 --> 00:23:57.049
surgical procedures called capsular shifts, ACP

00:23:57.049 --> 00:23:59.509
offers advantages like smaller incisions, less

00:23:59.509 --> 00:24:02.650
scarring, often less pain after surgery, avoiding

00:24:02.650 --> 00:24:05.650
the need to detach and reattach the subscapularis

00:24:05.650 --> 00:24:08.529
tendon, and potentially a quicker return to sports.

00:24:08.730 --> 00:24:10.950
And the results. Studies have reported quite

00:24:10.950 --> 00:24:13.589
promising success rates with ACP and appropriately

00:24:13.589 --> 00:24:16.230
selected patients who have true MDI. Okay, let's

00:24:16.230 --> 00:24:18.960
talk rotator cuff tears. A very common source

00:24:18.960 --> 00:24:21.539
of shoulder pain and weakness. What are some

00:24:21.539 --> 00:24:24.180
of the newer developments in arthroscopic repair

00:24:24.180 --> 00:24:26.900
techniques? Arthroscopic rotator cuff repair

00:24:26.900 --> 00:24:29.200
techniques have certainly come a long way. One

00:24:29.200 --> 00:24:31.579
promising advancement is the linked double row

00:24:31.579 --> 00:24:35.099
suture bridge or LDRS -B repair. That sounds

00:24:35.099 --> 00:24:38.099
complex, LDRS -B. It does, but the idea is to

00:24:38.099 --> 00:24:40.220
improve healing. Studies have suggested that

00:24:40.220 --> 00:24:42.259
this technique can lead to higher rates of tendon

00:24:42.259 --> 00:24:45.119
healing and potentially fewer repeat tears compared

00:24:45.119 --> 00:24:47.759
to traditional single row or even standard double

00:24:47.759 --> 00:24:50.190
row repairs. How does it work? The idea behind

00:24:50.190 --> 00:24:53.009
the suture bridge is to create a wider footprint

00:24:53.009 --> 00:24:55.950
of tendon -to -bone contact and provide more

00:24:55.950 --> 00:24:59.470
even pressure across the repair site, which theoretically

00:24:59.470 --> 00:25:01.690
promotes better healing conditions. But in knotless

00:25:01.690 --> 00:25:04.130
anchors. Yes. We're also seeing an increasing

00:25:04.130 --> 00:25:07.369
use of knotless anchors. These simplify the process

00:25:07.369 --> 00:25:10.009
of tying sutures and securing the tendon to the

00:25:10.009 --> 00:25:13.109
bone arthrostatically. This can potentially reduce

00:25:13.109 --> 00:25:16.029
the risk of complications related to knots, like

00:25:16.029 --> 00:25:18.819
irritation or suture breakage, and maybe speed

00:25:18.819 --> 00:25:22.559
up the surgery slightly. Interesting. Now, subcoracoid

00:25:22.559 --> 00:25:24.240
impingement is something many people haven't

00:25:24.240 --> 00:25:26.980
heard of, but it can be a source of pain in the

00:25:26.980 --> 00:25:29.779
front of the shoulder. How is it diagnosed and

00:25:29.779 --> 00:25:32.359
treated arthroscopically? Right, subcoracoid

00:25:32.359 --> 00:25:35.339
impingement happens when the space between the

00:25:35.339 --> 00:25:37.480
coracoid process, that little hook -like bone

00:25:37.480 --> 00:25:39.299
at the front of your shoulder blade and the humeral

00:25:39.299 --> 00:25:42.799
head becomes too narrow. This often causes friction

00:25:42.799 --> 00:25:45.279
on the subscapularis tendon which runs between

00:25:45.279 --> 00:25:47.900
them. What causes it? It can be caused by repetitive

00:25:47.900 --> 00:25:50.200
movements or certain anatomical variations where

00:25:50.200 --> 00:25:52.579
the coracoid is maybe a bit larger or angled

00:25:52.579 --> 00:25:55.460
differently. And diagnosis. Imaging, especially

00:25:55.460 --> 00:25:57.980
CT scans that can precisely measure the distance

00:25:57.980 --> 00:26:00.519
between the coracoid and humerus and calculate

00:26:00.519 --> 00:26:03.180
various indices, can be very helpful in making

00:26:03.180 --> 00:26:06.240
the diagnosis. And the arthroscopic fix. Arthroscopic

00:26:06.240 --> 00:26:09.539
coracoplasty. This involves using a small high

00:26:09.539 --> 00:26:12.259
-speed burr to carefully shave away a small amount

00:26:12.259 --> 00:26:14.920
of bone from the tip or underside of the coracoid

00:26:14.920 --> 00:26:18.140
process to widen that space and effectively relieve

00:26:18.140 --> 00:26:20.519
the impingement. How do you find the coracoid

00:26:20.519 --> 00:26:23.200
during surgery? It's crucial to identify it accurately.

00:26:23.579 --> 00:26:25.920
The technique can vary slightly depending on

00:26:25.920 --> 00:26:28.180
whether the subscapularis tendon underneath it

00:26:28.180 --> 00:26:31.759
is intact or has retracted due to a tear. A helpful

00:26:31.759 --> 00:26:33.640
landmark in cases where the subscapularis has

00:26:33.640 --> 00:26:36.119
retracted is the comma sign, which includes the

00:26:36.119 --> 00:26:38.140
coracohumeral ligament attaching near there.

00:26:38.539 --> 00:26:40.940
OK. The subscapularis tendon itself, one of the

00:26:40.940 --> 00:26:43.460
rotator cuff muscles, can also be torn. Is that

00:26:43.460 --> 00:26:45.779
being recognized more now with arthroscopic surgery?

00:26:45.920 --> 00:26:48.359
Absolutely. The subscapularis is a really important

00:26:48.359 --> 00:26:50.799
rotator cuff muscle. It plays a crucial role

00:26:50.539 --> 00:26:53.539
in shoulder movement and stability, particularly

00:26:53.539 --> 00:26:55.599
internal rotation, turning your arm inwards.

00:26:55.759 --> 00:26:58.039
And it used to be missed? Historically, yes.

00:26:58.579 --> 00:27:01.079
Tears of the subscapularis, especially partial

00:27:01.079 --> 00:27:03.579
tears on the droid side, were often missed with

00:27:03.579 --> 00:27:06.680
traditional open surgical approaches. It even

00:27:06.680 --> 00:27:09.519
got called the forgotten tendon. Wow. But the

00:27:09.519 --> 00:27:11.940
ability to directly visualize the tendon with

00:27:11.940 --> 00:27:14.700
shoulder arthroscopy has significantly increased

00:27:14.700 --> 00:27:16.900
our recognition and diagnosis of these tears.

00:27:17.240 --> 00:27:20.279
How is it repaired arthroscopically? Arthroscopic

00:27:20.279 --> 00:27:22.720
repair typically involves establishing standard

00:27:22.720 --> 00:27:25.559
entry portals around the shoulder, then performing

00:27:25.559 --> 00:27:28.460
an anterior release to carefully free up the

00:27:28.460 --> 00:27:30.839
tendon from any scar tissue before reattaching

00:27:30.839 --> 00:27:33.660
it to its insertion point on the lesser tuberosity

00:27:33.660 --> 00:27:37.339
using suture anchors. Any specific risks? Surgeons

00:27:37.339 --> 00:27:39.819
have to be particularly careful during that anterior

00:27:39.819 --> 00:27:42.579
release to avoid any injury to the nearby axillary

00:27:42.579 --> 00:27:45.789
nerve, which runs quite close. Sadly, not all

00:27:45.789 --> 00:27:48.589
rotator cuff tears are repairable. What are the

00:27:48.589 --> 00:27:51.470
options when a tear is just too big or retracted,

00:27:51.589 --> 00:27:53.880
deemed irreparable? That's a tough situation.

00:27:54.019 --> 00:27:56.339
For massive rotator cuff tears that can't be

00:27:56.339 --> 00:27:58.579
repaired directly back to the bone, there are

00:27:58.579 --> 00:28:00.779
several surgical and non -surgical management

00:28:00.779 --> 00:28:03.579
options. Like what? A subacromial balloon spacer

00:28:03.579 --> 00:28:06.480
can be inserted arthroscopically. This is like

00:28:06.480 --> 00:28:09.400
a temporary inflatable cushion placed between

00:28:09.400 --> 00:28:11.779
the humeral head and the acromion. A cushion?

00:28:11.799 --> 00:28:14.140
How does that help? It helps to keep the humeral

00:28:14.140 --> 00:28:16.920
head centered in the socket, reducing pain and

00:28:16.920 --> 00:28:19.539
improving function, especially in older patients

00:28:19.539 --> 00:28:21.880
who still have a good range of motion and a strong

00:28:21.880 --> 00:28:24.910
d - muscle, but it's not suitable for everyone

00:28:24.910 --> 00:28:27.210
and it's not a permanent fix. Other options.

00:28:27.549 --> 00:28:29.890
The long head of the biceps tendon can also be

00:28:29.890 --> 00:28:32.809
repurposed. It can be used as a vascularized

00:28:32.809 --> 00:28:35.269
graft in a technique called the biceps patch

00:28:35.269 --> 00:28:38.349
for superior capsule reconstruction where the

00:28:38.349 --> 00:28:40.910
top part of the shoulder joint capsule is reinforced

00:28:40.910 --> 00:28:43.849
or rebuilt. Using your own tissue. Exactly. Another

00:28:43.849 --> 00:28:46.670
well -established option is a latissimus dorsi

00:28:46.670 --> 00:28:49.430
tendon transfer. Moving a back muscle. Right.

00:28:49.670 --> 00:28:51.849
The latissimus dorsi muscle from your back is

00:28:51.849 --> 00:28:54.029
rerouted to the shoulder to help with external

00:28:54.029 --> 00:28:56.670
rotation and abduction, typically in younger,

00:28:56.730 --> 00:28:59.329
more active patients with tears on the back and

00:28:59.329 --> 00:29:02.670
top of the rotator cuff, provided their subscapularis

00:29:02.670 --> 00:29:05.690
tendon is intact. And newer transfers. More recently,

00:29:05.910 --> 00:29:08.250
transferring the lower trapezius tendon, often

00:29:08.250 --> 00:29:11.230
using a donated Achilles tendon as a bridge graft,

00:29:11.670 --> 00:29:14.829
has been explored as another alternative. This

00:29:14.829 --> 00:29:16.930
might offer a better line of pull for certain

00:29:16.930 --> 00:29:19.609
types of irreparable tears. Lots of ingenuity

00:29:19.609 --> 00:29:22.089
there. Let's talk about calcific tendonitis,

00:29:22.210 --> 00:29:24.569
where calcium deposits form in the rotator cuff

00:29:24.569 --> 00:29:27.430
tendons. That can be incredibly painful, right?

00:29:27.470 --> 00:29:29.869
Oh, extremely painful sometimes. The initial

00:29:29.869 --> 00:29:32.309
treatment for calcific tendonitis is usually

00:29:32.309 --> 00:29:35.269
non -surgical rest, pain medication, physical

00:29:35.269 --> 00:29:37.950
therapy, sometimes injections like cortisone

00:29:37.950 --> 00:29:40.009
or even procedures to try and break up the calcium

00:29:40.009 --> 00:29:42.990
with needles. But if that fails? If these conservative

00:29:42.990 --> 00:29:45.930
measures don't provide relief, arthroscopic removal

00:29:45.930 --> 00:29:48.269
of the calcium deposits can be a very effective

00:29:48.269 --> 00:29:51.440
option. goes in with the scope, finds a deposit,

00:29:51.640 --> 00:29:53.720
and essentially scrapes or sucks it out. Are

00:29:53.720 --> 00:29:55.720
there times when arthroscopy isn't suitable?

00:29:56.119 --> 00:29:58.579
Yes, there are a few situations. For example,

00:29:58.720 --> 00:30:00.700
if the calcium deposit is already in the process

00:30:00.700 --> 00:30:03.180
of being naturally resorbed or absorbed by the

00:30:03.180 --> 00:30:06.599
body, surgery might not be needed. Or if multiple

00:30:06.599 --> 00:30:08.859
tendons are involved, or if the patient also

00:30:08.859 --> 00:30:11.779
has significant arthritis, frozen shoulder, or

00:30:11.779 --> 00:30:15.029
has had previous shoulder surgery, It might complicate

00:30:15.029 --> 00:30:17.529
things. But generally effective. In appropriately

00:30:17.529 --> 00:30:20.589
selected cases, yes. Arthroscopic removal of

00:30:20.589 --> 00:30:23.069
a calcium has reported high success rates in

00:30:23.069 --> 00:30:26.150
reducing pain and improving function. SLAP tears,

00:30:26.869 --> 00:30:28.990
injuries to the superior labrum where the biceps

00:30:28.990 --> 00:30:31.859
tendon attaches. seem common, especially in athletes

00:30:31.859 --> 00:30:33.960
who do a lot of overhead activities. They are.

00:30:34.220 --> 00:30:37.000
SLAP tears, standing for superior labrum interior

00:30:37.000 --> 00:30:39.740
to posterior, involve a tear in the top part

00:30:39.740 --> 00:30:42.180
of the labrum, often affecting the anchor point

00:30:42.180 --> 00:30:44.420
of the long head of the biceps tendon. They're

00:30:44.420 --> 00:30:46.680
frequently caused by repetitive overhead motions,

00:30:46.940 --> 00:30:49.380
like throwing or swimming, or by sudden injuries,

00:30:49.619 --> 00:30:51.960
like falls onto an outstretched arm or a direct

00:30:51.960 --> 00:30:55.460
blow to the shoulder. Diagnosis tricky. Diagnosing

00:30:55.460 --> 00:30:57.779
SLA peers can be challenging based on physical

00:30:57.779 --> 00:31:00.660
examination alone, as the symptoms can overlap

00:31:00.660 --> 00:31:03.220
with other shoulder problems, so imaging like

00:31:03.220 --> 00:31:07.759
MRI or MRA is often helpful. and treatment. Arthroscopic

00:31:07.759 --> 00:31:10.460
repair is the main treatment approach for significant

00:31:10.460 --> 00:31:13.759
symptomatic SLAP tears, especially in younger

00:31:13.759 --> 00:31:17.160
active individuals. SLAP lesions are classified

00:31:17.160 --> 00:31:19.720
into several types based on the pattern of the

00:31:19.720 --> 00:31:21.380
tear. Like types three and four. Right, those

00:31:21.380 --> 00:31:23.920
are examples. Type three involves a bucket handle

00:31:23.920 --> 00:31:26.680
tear of the superior labrum itself where the

00:31:26.680 --> 00:31:29.579
torn piece hangs down. The biceps anchor is intact.

00:31:30.119 --> 00:31:32.339
Type four also has a bucket handle tear, but

00:31:32.339 --> 00:31:34.940
this one extends into the biceps tendon anchor.

00:31:35.130 --> 00:31:37.930
Any specific tests during an exam? There are

00:31:37.930 --> 00:31:40.349
several specific clinical tests surgeons use,

00:31:40.609 --> 00:31:42.950
like the Resisted Supination External Rotation

00:31:42.950 --> 00:31:45.589
Test and the Clunk Test, that can raise suspicion

00:31:45.589 --> 00:31:48.609
for SLA pter, but none are perfectly accurate

00:31:48.609 --> 00:31:52.349
on their own. Okay. Biceps tenodesis, a procedure

00:31:52.349 --> 00:31:54.849
to surgically fix the long head of the biceps

00:31:54.849 --> 00:31:57.509
tendon in a new location, is another common surgery.

00:31:57.680 --> 00:31:59.980
When is that typically done? Biceps tenodesis

00:31:59.980 --> 00:32:02.779
is indicated for various reasons. One common

00:32:02.779 --> 00:32:05.079
reason is pain that seems to be coming primarily

00:32:05.079 --> 00:32:08.359
from the biceps tendon itself, often called biceps

00:32:08.359 --> 00:32:11.400
tendonitis. It's also often performed when there's

00:32:11.400 --> 00:32:14.440
a significant tear in the biceps tendon or as

00:32:14.440 --> 00:32:16.920
part of the treatment for certain types of SLAP

00:32:16.920 --> 00:32:19.519
tears, particularly those where the biceps anchor

00:32:19.519 --> 00:32:22.819
is unstable or the tear extends into the tendon

00:32:22.819 --> 00:32:25.779
or even sometimes in older patients instead of

00:32:25.779 --> 00:32:29.589
repairing the SLAP. It's also used if a previous

00:32:29.589 --> 00:32:33.960
SLAP repair has failed. There aren't many absolute

00:32:33.960 --> 00:32:36.299
contraindications, but surgeons might be more

00:32:36.299 --> 00:32:38.440
cautious in patients with significant other medical

00:32:38.440 --> 00:32:40.940
problems or perhaps in older individuals with

00:32:40.940 --> 00:32:42.880
very low functional demands where the symptoms

00:32:42.880 --> 00:32:45.339
aren't too bothersome. What's the preferred technique?

00:32:45.720 --> 00:32:47.720
Techniques vary, but one preferred technique

00:32:47.720 --> 00:32:50.980
mentioned in the source is an arthroscopic intraarticular

00:32:50.980 --> 00:32:54.680
tenodesis. Here, the tendon is cut inside the

00:32:54.680 --> 00:32:57.519
joint and then reattached to the humerus right

00:32:57.519 --> 00:32:59.680
at the edge of the joint cartilage. Other ways.

00:33:00.039 --> 00:33:03.119
Yes, there are also endoscopic -assisted techniques.

00:33:03.440 --> 00:33:06.500
These involve making a small incision lower down,

00:33:06.539 --> 00:33:09.220
often in the armpit area or just below the pec

00:33:09.220 --> 00:33:12.339
muscle, and using an endoscope to help visualize

00:33:12.339 --> 00:33:15.400
and secure the tendon to the bone in the subpectoral

00:33:15.400 --> 00:33:18.119
space. Sometimes a special retractor called a

00:33:18.119 --> 00:33:20.579
homon is used to help with exposure down there.

00:33:20.839 --> 00:33:23.559
Got it. Frozen shoulder or adhesive capsulitis

00:33:23.559 --> 00:33:25.720
can be incredibly painful and limit movement

00:33:25.720 --> 00:33:28.359
significantly. When might surgery be recommended

00:33:28.359 --> 00:33:31.140
for that? Patients with frozen shoulder experience

00:33:31.140 --> 00:33:33.519
this really painful and progressive restriction

00:33:33.519 --> 00:33:36.180
in both their active and passive range of motion

00:33:36.180 --> 00:33:39.289
in the shoulder. It can be debilitating. How

00:33:39.289 --> 00:33:41.650
is it usually treated first? Initially, treatment

00:33:41.650 --> 00:33:44.670
is usually conservative. That means pain medication,

00:33:45.049 --> 00:33:47.450
maybe anti -inflammatories, intensive physical

00:33:47.450 --> 00:33:49.829
therapy focused on stretching, and sometimes

00:33:49.829 --> 00:33:52.049
cortisone injections into the jade. But if that

00:33:52.049 --> 00:33:54.309
doesn't work? If these non -surgical treatments

00:33:54.309 --> 00:33:56.509
fail to restore adequate range of motion and

00:33:56.509 --> 00:33:59.029
relieve pain after a reasonable period, often

00:33:59.029 --> 00:34:01.750
several months, then arthroscopic pancapsular

00:34:01.750 --> 00:34:04.410
release is often recommended. Pancapsular release.

00:34:04.670 --> 00:34:07.470
Yes, this involves surgically releasing the tightened

00:34:07.470 --> 00:34:09.750
and thickened joint capsule from the inside of

00:34:09.750 --> 00:34:12.730
the joint using arthroscopic instruments, essentially

00:34:12.730 --> 00:34:15.030
cutting the tight tissue all around the joint,

00:34:15.329 --> 00:34:18.250
hence pancapsular. Does it fully restore motion?

00:34:18.570 --> 00:34:21.530
It can significantly improve the range of motion,

00:34:21.690 --> 00:34:24.289
often dramatically, but it's important for patients

00:34:24.289 --> 00:34:26.530
to understand that regaining the absolute full

00:34:26.530 --> 00:34:28.809
range of motion they had before the frozen shoulder,

00:34:29.250 --> 00:34:31.170
making it perfectly comparable to their other

00:34:31.170 --> 00:34:33.670
arm, can sometimes still be a challenge even

00:34:33.670 --> 00:34:36.150
after successful surgery and rehab. As we get

00:34:36.150 --> 00:34:39.469
older, osteoarthritis of the glenohumeral joint,

00:34:40.010 --> 00:34:42.269
that wear and tear in the main shoulder joint,

00:34:42.769 --> 00:34:45.150
becomes more common. How is it managed in the

00:34:45.150 --> 00:34:48.619
earlier stages before replacement? Glenohumeral

00:34:48.619 --> 00:34:51.800
osteoarthritis, or GHOA, is a degenerative condition.

00:34:51.960 --> 00:34:53.820
And yes, unfortunately, it becomes more prevalent

00:34:53.820 --> 00:34:57.000
with age. In the earlier stages, before the arthritis

00:34:57.000 --> 00:34:59.340
is too severe and causing bone -on -bone pain,

00:34:59.980 --> 00:35:02.019
surgeons might consider conservative surgical

00:35:02.019 --> 00:35:04.800
management. This primarily involves arthroscopy

00:35:04.800 --> 00:35:07.320
to go in and essentially clean up the joint.

00:35:07.500 --> 00:35:09.690
What does cleaning up involve? It can include

00:35:09.690 --> 00:35:12.329
removing loose fragments of cartilage, smoothing

00:35:12.329 --> 00:35:14.929
out rough surfaces on the cartilage or bone spurs,

00:35:15.110 --> 00:35:17.789
maybe releasing a tight capsule, and addressing

00:35:17.789 --> 00:35:20.690
any associated soft tissue issues like biceps

00:35:20.690 --> 00:35:23.510
tendon problems or small rotator cuff tears.

00:35:23.829 --> 00:35:26.550
The goal? The goal is primarily to relieve pain

00:35:26.550 --> 00:35:28.809
and improve function, maybe delaying the need

00:35:28.809 --> 00:35:31.329
for a joint replacement. But it's important to

00:35:31.329 --> 00:35:34.210
realize it's not a long term fix for the underlying

00:35:34.210 --> 00:35:37.309
arthritis itself. It's more palliative. Flail

00:35:37.309 --> 00:35:39.690
shoulder is a very debilitating condition where

00:35:39.690 --> 00:35:43.269
the arm is essentially paralyzed. Can arthroscopy

00:35:43.269 --> 00:35:45.469
play any role in helping these patients? Flail

00:35:45.469 --> 00:35:47.949
shoulder often results from severe nerve injuries

00:35:47.949 --> 00:35:50.610
like brachial plexus injuries. or muscle paralysis,

00:35:50.969 --> 00:35:53.130
leading to a significant loss of the ability

00:35:53.130 --> 00:35:55.750
to actively move the arm. It just hangs there.

00:35:56.090 --> 00:35:58.349
So what can be done? In certain cases, where

00:35:58.349 --> 00:36:00.469
the goal is mainly to stabilize the shoulder

00:36:00.469 --> 00:36:02.550
joint to allow for better use of the hand, especially

00:36:02.550 --> 00:36:05.170
for tasks at waist level, a procedure called

00:36:05.170 --> 00:36:07.610
glenohumeral arthrodesis might be considered.

00:36:08.170 --> 00:36:10.949
Arthrodesis. Fusing the joint. Exactly. Surgically

00:36:10.949 --> 00:36:13.150
fusing the humeral head to the glenoid socket.

00:36:14.139 --> 00:36:16.039
Arthroscopic assisted techniques can be used

00:36:16.039 --> 00:36:18.659
here to help prepare the joint surfaces for fusion

00:36:18.659 --> 00:36:21.679
removing any remaining cartilage and also to

00:36:21.679 --> 00:36:24.019
help guide the placement of the wires or screws

00:36:24.019 --> 00:36:26.599
that hold the bones together rigidly while they

00:36:26.599 --> 00:36:30.420
heal into one solid piece. Sometimes loose fragments

00:36:30.420 --> 00:36:32.780
of cartilage or bone can float around inside

00:36:32.780 --> 00:36:35.219
the shoulder joint causing pain and mechanical

00:36:35.219 --> 00:36:37.880
symptoms like catching or locking. How are those

00:36:37.880 --> 00:36:40.400
addressed? Arthroscopic removal of these loose

00:36:40.400 --> 00:36:43.239
bodies is an excellent and often the preferred

00:36:43.239 --> 00:36:45.579
alternative to traditional open surgery. Why

00:36:45.579 --> 00:36:47.719
is better? It allows the surgeon to thoroughly

00:36:47.719 --> 00:36:50.539
visualize the entire inside of the joint, find

00:36:50.539 --> 00:36:52.599
all the fragments even ones hiding in corners,

00:36:53.119 --> 00:36:55.300
and precisely remove them with minimal damage

00:36:55.300 --> 00:36:58.079
to the surrounding healthy tissues. Smaller incisions,

00:36:58.239 --> 00:37:01.360
quicker recovery usually. Sadly, infections can

00:37:01.360 --> 00:37:03.059
sometimes occur in the shoulder joint. How are

00:37:03.059 --> 00:37:04.860
those managed particularly using arthroscopic?

00:37:05.000 --> 00:37:07.000
techniques. Septic arthritis of the shoulder

00:37:07.000 --> 00:37:09.219
and infection within the joint is relatively

00:37:09.219 --> 00:37:11.800
rare but has seen perhaps a slight increase in

00:37:11.800 --> 00:37:13.880
incidence following injections around the shoulder.

00:37:14.219 --> 00:37:16.420
And the treatment. The preferred treatment approach

00:37:16.420 --> 00:37:19.559
is usually plomped arthroscopic debridement and

00:37:19.559 --> 00:37:21.920
irrigation. Washing it out. Essentially, yes.

00:37:22.000 --> 00:37:24.400
It allows for a thorough cleaning and flushing

00:37:24.400 --> 00:37:27.300
out of the infected joint fluid and any pus or

00:37:27.300 --> 00:37:30.019
debris. And at the same time, the surgeon can

00:37:30.019 --> 00:37:32.960
visualize and potentially address any other associated

00:37:32.960 --> 00:37:36.320
problems like rotator cuff tears that might be

00:37:36.320 --> 00:37:39.510
present or contributing. Even bone cysts in the

00:37:39.510 --> 00:37:41.469
proximal humerus, the upper part of the arm bone,

00:37:41.889 --> 00:37:44.329
can be treated using minimally invasive techniques

00:37:44.329 --> 00:37:46.789
now. How does that work? Yes, endoscopic cure

00:37:46.789 --> 00:37:49.750
-tage is a technique used to treat certain benign

00:37:49.750 --> 00:37:52.929
bone cysts in the proximal humerus. Endoscopic.

00:37:53.150 --> 00:37:55.730
like arthroscopic, but inside the bone. Kind

00:37:55.730 --> 00:37:58.110
of. It involves making small incisions to create

00:37:58.110 --> 00:38:00.909
portals directly into the bone cyst, then using

00:38:00.909 --> 00:38:02.969
specialized instruments under endoscopic camera

00:38:02.969 --> 00:38:05.070
guidance to scrape out the lining of the cyst.

00:38:05.570 --> 00:38:08.050
The goal is to be less invasive than traditional

00:38:08.050 --> 00:38:09.949
open surgery, where you might have to make a

00:38:09.949 --> 00:38:12.170
larger window in the bone, potentially leading

00:38:12.170 --> 00:38:14.929
to faster healing and maybe a higher success

00:38:14.929 --> 00:38:17.670
rate in resolving the cyst. A vascular necrosis

00:38:17.670 --> 00:38:19.670
of the humeral head, where the blood supply to

00:38:19.670 --> 00:38:22.170
the top of the arm bone is disrupted, is a serious

00:38:22.170 --> 00:38:26.300
condition. Can arthroscopy help there too? Arthroscopic

00:38:26.300 --> 00:38:28.980
assisted cord decompression and fibular strut

00:38:28.980 --> 00:38:31.639
grafting is a technique used to try and treat

00:38:31.639 --> 00:38:34.679
humeral head avascular necrosis, particularly

00:38:34.679 --> 00:38:37.800
in its earlier stages, before the head collapses.

00:38:38.320 --> 00:38:40.920
Cord decompression. That involves drilling small

00:38:40.920 --> 00:38:43.539
channels into the affected area of the humeral

00:38:43.539 --> 00:38:46.320
head to relieve pressure and hopefully stimulate

00:38:46.320 --> 00:38:49.199
improved blood flow or healing. And the fibular

00:38:49.199 --> 00:38:52.150
graft. This is often supplemented by inserting

00:38:52.150 --> 00:38:55.210
small structural bone grafts, often taken from

00:38:55.210 --> 00:38:57.530
the fibula bone in the lower leg, into those

00:38:57.530 --> 00:39:00.170
channels. These grafts provide mechanical support

00:39:00.170 --> 00:39:02.469
and aim to prevent the humeral head from collapsing.

00:39:02.969 --> 00:39:05.570
The arthroscopic assistance allows for more precise

00:39:05.570 --> 00:39:07.789
placement of these channels and grafts with smaller

00:39:07.789 --> 00:39:10.550
incisions compared to open methods. What about

00:39:10.550 --> 00:39:12.829
patients who have already had a shoulder replacement

00:39:12.829 --> 00:39:16.230
and are now experiencing new problems? Can arthroscopy

00:39:16.230 --> 00:39:18.989
still be a useful tool for them? Yes, absolutely.

00:39:19.440 --> 00:39:21.880
Arthroscopy can definitely be valuable even after

00:39:21.880 --> 00:39:24.320
a patient has undergone shoulder arthroplasty

00:39:24.320 --> 00:39:27.079
or joint replacement What kind of problems it

00:39:27.079 --> 00:39:29.900
can be used to diagnose and sometimes treat various

00:39:29.900 --> 00:39:32.099
complications that can arise after replacement

00:39:32.099 --> 00:39:35.500
things like infection around the prosthetic joint

00:39:35.500 --> 00:39:37.780
instability where the replacement feels loose

00:39:37.780 --> 00:39:40.840
or dislocates Impingement issues where tissues

00:39:40.840 --> 00:39:44.059
are getting pinched new rotator cuff tears that

00:39:44.059 --> 00:39:46.820
can still occur and even loosening of the components

00:39:46.820 --> 00:39:50.409
of the artificial joint Is it harder to do? Performing

00:39:50.409 --> 00:39:52.590
arthroscopy in a shoulder that has already had

00:39:52.590 --> 00:39:54.670
a replacement is definitely technically more

00:39:54.670 --> 00:39:57.090
challenging. The anatomy is altered, you have

00:39:57.090 --> 00:39:59.750
the implants in the way, and scar tissue can

00:39:59.750 --> 00:40:02.309
make visualization difficult. So it really requires

00:40:02.309 --> 00:40:04.710
a surgeon with significant experience in this

00:40:04.710 --> 00:40:08.610
specific area. Often a posterior portal, an entry

00:40:08.610 --> 00:40:10.809
point from the back of the shoulder, is preferred

00:40:10.809 --> 00:40:12.929
in these cases to try and avoid the implants

00:40:12.929 --> 00:40:16.699
at the front. Okay. Dislocations of the chromioclavicular

00:40:16.699 --> 00:40:19.039
joint, the AC joint where your collarbone separates

00:40:19.039 --> 00:40:21.579
from your shoulder blade, are common injuries,

00:40:21.719 --> 00:40:24.739
especially in sports. How are those treated arthroscopically?

00:40:25.139 --> 00:40:27.500
Arthroscopic assisted reduction and fixation

00:40:27.500 --> 00:40:29.820
techniques are increasingly used to treat the

00:40:29.820 --> 00:40:33.139
more severe ACJ dislocations, the ones where

00:40:33.139 --> 00:40:35.880
the clavicle is significantly elevated. How is

00:40:35.880 --> 00:40:39.239
it fixed? These techniques often involve using

00:40:39.239 --> 00:40:41.719
strong sutures or tapes, like the commercially

00:40:41.719 --> 00:40:44.880
available tightrope and fiber tape systems, passed

00:40:44.880 --> 00:40:48.119
around the coracoid process and through or around

00:40:48.119 --> 00:40:50.719
the clavicle to pull the clavicle back down into

00:40:50.719 --> 00:40:53.179
its correct position relative to the acromion

00:40:53.179 --> 00:40:55.659
and then secure it there while the ligaments

00:40:55.659 --> 00:40:58.489
heal. does it always stay reduced? While these

00:40:58.489 --> 00:41:00.469
methods aim to restore the normal alignment,

00:41:01.010 --> 00:41:03.010
some degree of loss of the initial reduction

00:41:03.010 --> 00:41:05.349
can sometimes occur over time as things settle

00:41:05.349 --> 00:41:08.090
or stretch slightly. Interestingly, there's some

00:41:08.090 --> 00:41:10.590
evidence emerging to suggest that slightly over

00:41:10.590 --> 00:41:12.670
-reducing the joint during the initial surgery

00:41:12.670 --> 00:41:15.190
might actually be protective against the joint

00:41:15.190 --> 00:41:18.590
subluxing or dislocating again later. The corcoclavicular

00:41:18.590 --> 00:41:20.789
ligaments are crucial for the stability of that

00:41:20.789 --> 00:41:24.030
AC joint. Can those be reconstructed arthroscopically

00:41:24.030 --> 00:41:26.070
if they're completely torn and may be retracted?

00:41:26.219 --> 00:41:29.179
Yes, there are arthroscopic techniques specifically

00:41:29.179 --> 00:41:32.099
for reconstructing the coracoclavicular ligaments,

00:41:32.500 --> 00:41:34.920
which are vital for holding the AC joint stable.

00:41:35.159 --> 00:41:37.630
Using what? These procedures typically involve

00:41:37.630 --> 00:41:40.610
using donated tissue and allograft tendon to

00:41:40.610 --> 00:41:43.329
create new ligaments. The graft is passed around

00:41:43.329 --> 00:41:45.409
the coracoid and through tunnels drilled in the

00:41:45.409 --> 00:41:48.130
clavicle and then secured with strong fixation

00:41:48.130 --> 00:41:50.630
devices, all done through small arthroscopic

00:41:50.630 --> 00:41:53.730
incisions and portals. When osteoarthritis in

00:41:53.730 --> 00:41:56.590
the AC joint itself becomes painful, sometimes

00:41:56.590 --> 00:41:59.309
a small piece of the end of the clavicle is removed

00:41:59.309 --> 00:42:02.329
at distal clavicle excision. How is that done

00:42:02.329 --> 00:42:05.449
arthroscopically? Arthrostopic acromioclavicular

00:42:05.449 --> 00:42:08.289
joint resection, sometimes called a Mumford procedure

00:42:08.289 --> 00:42:11.010
arthroscopically, is a common procedure for persistent

00:42:11.010 --> 00:42:13.630
pain and sometimes instability related to ACJ,

00:42:13.670 --> 00:42:15.730
osteoarthritis, or impingement. What's involved?

00:42:16.190 --> 00:42:18.650
Using a small bur through arthroscopic portals,

00:42:18.889 --> 00:42:20.909
the surgeon removes a small portion, maybe 5

00:42:20.909 --> 00:42:23.530
to 10 millimeters, of the very end of the distal

00:42:23.530 --> 00:42:26.650
clavicle. Key considerations. A key consideration

00:42:26.650 --> 00:42:29.809
for the surgeon is how much bone to remove. Taking

00:42:29.809 --> 00:42:32.389
too little might not relieve the symptoms, but

00:42:32.389 --> 00:42:34.909
taking too much could potentially destabilize

00:42:34.909 --> 00:42:37.510
the joint, especially if the coracoclavicular

00:42:37.510 --> 00:42:40.929
ligaments aren't perfectly intact. While the

00:42:40.929 --> 00:42:43.190
arthroscopic approach offers advantages over

00:42:43.190 --> 00:42:46.150
open surgery, like smaller incisions, surgeons

00:42:46.150 --> 00:42:48.309
still need to be careful with portal placement

00:42:48.309 --> 00:42:50.829
to avoid potential complications, like nerve

00:42:50.829 --> 00:42:53.480
injury. Also, some studies have suggested that

00:42:53.480 --> 00:42:55.820
in patients who are also undergoing rotator cuff

00:42:55.820 --> 00:42:58.920
repair and happen to have ACG arthritis, performing

00:42:58.920 --> 00:43:01.400
this distal clavicle excision at the same time

00:43:01.400 --> 00:43:03.900
might not actually provide any additional benefit

00:43:03.900 --> 00:43:10.820
in terms of outcome. Sometimes it can cause pain,

00:43:11.000 --> 00:43:13.079
right? How is that addressed? Exactly. While

00:43:13.079 --> 00:43:16.300
often asymptomatic, a mobile mesoacromial fragment,

00:43:16.639 --> 00:43:19.280
essentially an unfused growth center of the acromeon,

00:43:19.320 --> 00:43:21.760
can sometimes be a source of pain, clicking,

00:43:22.059 --> 00:43:24.099
and impingement -like symptoms in the shoulder.

00:43:24.539 --> 00:43:27.320
How do you confirm it's the cause? Careful diagnosis

00:43:27.320 --> 00:43:30.219
is important. This often involves pinpointing

00:43:30.219 --> 00:43:33.300
tenderness directly over the fragment and sometimes

00:43:33.300 --> 00:43:35.960
injecting a local anesthetic like lidocaine around

00:43:35.960 --> 00:43:38.300
the suspected non -union site to see if that

00:43:38.300 --> 00:43:40.380
temporarily relieves the pain and the treatment.

00:43:41.070 --> 00:43:43.710
Arthroscopic excision, where the small separate

00:43:43.710 --> 00:43:46.730
piece of bone is surgically removed using arthroscopic

00:43:46.730 --> 00:43:49.610
instruments, is a described alternative to open

00:43:49.610 --> 00:43:51.889
surgery, either excision or trying to fix it

00:43:51.889 --> 00:43:54.849
with screws. This minimally invasive approach

00:43:54.849 --> 00:43:57.710
potentially leads to less post -operative pain

00:43:57.710 --> 00:44:00.409
and less weakness in the deltoid muscle which

00:44:00.409 --> 00:44:03.320
attaches there. snapping scapula syndrome, where

00:44:03.320 --> 00:44:06.480
you feel or hear a grinding or popping sensation

00:44:06.480 --> 00:44:08.860
as your shoulder blade moves over the ribs that

00:44:08.860 --> 00:44:10.739
can also be treated arthroscopically. How does

00:44:10.739 --> 00:44:13.260
that work? Yes, for snapping scapula syndrome,

00:44:13.360 --> 00:44:15.300
which is often caused by inflammation of the

00:44:15.300 --> 00:44:17.719
bursa between the scapula and chest wall, or

00:44:17.719 --> 00:44:20.400
sometimes a bony prominence on the scapula, both

00:44:20.400 --> 00:44:22.860
open and arthroscopic treatment options exist.

00:44:23.320 --> 00:44:26.340
Arthroscopic approaches typically involve either

00:44:26.340 --> 00:44:29.340
removing the inflamed bursa a brosectomy, or

00:44:29.340 --> 00:44:31.559
sometimes partially removing a small corner of

00:44:31.559 --> 00:44:33.960
the scapula, if that's rubbing, a partial scapelectomy.

00:44:34.139 --> 00:44:36.360
Advantages of arthroscopy. Potential advantages

00:44:36.360 --> 00:44:39.260
over open surgery include quicker recovery and

00:44:39.260 --> 00:44:42.179
less disruption to the surrounding muscles. Specific

00:44:42.179 --> 00:44:44.760
portal placements, like the medial and bell portals,

00:44:45.099 --> 00:44:47.780
are used to access that space between the scapula

00:44:47.780 --> 00:44:50.400
and the rib cage, the scapula thoracic space.

00:44:50.420 --> 00:44:52.989
Any dangers back there? Yes, surgeons need to

00:44:52.989 --> 00:44:56.070
be very careful during scapula thoracic arthroscopy

00:44:56.070 --> 00:44:59.150
to avoid injuring nearby nerves and blood vessels,

00:44:59.329 --> 00:45:02.050
like the long thoracic nerve or the dorsal scapular

00:45:02.050 --> 00:45:04.050
nerve and artery. What about other conditions

00:45:04.050 --> 00:45:06.929
affecting that scapula thoracic area, like bursitis

00:45:06.929 --> 00:45:10.389
specifically, or bony growths called osteochondromas?

00:45:10.510 --> 00:45:12.769
Scapula thoracic bursitis, just the inflammation

00:45:12.769 --> 00:45:15.050
of the bursa without necessarily a bony cause,

00:45:15.530 --> 00:45:18.010
and osteochondromas, which are benign bony growths

00:45:18.010 --> 00:45:19.710
that can occur on the underside of the scapula

00:45:19.710 --> 00:45:22.500
or on the ribs, can also be addressed arthroscopically

00:45:22.500 --> 00:45:25.619
or endoscopically. Imaging, including CT scans

00:45:25.619 --> 00:45:28.840
and MRI, is important for diagnosis, especially

00:45:28.840 --> 00:45:32.159
to see the exact location and size of an osteochondroma.

00:45:32.719 --> 00:45:35.219
Endoscopic resection of osteochondromas in the

00:45:35.219 --> 00:45:38.260
scapula thoracic space has been shown to be effective,

00:45:38.300 --> 00:45:40.539
again with potentially smaller incisions and

00:45:40.539 --> 00:45:50.679
a faster recovery compared to open surgery. is

00:45:50.679 --> 00:45:53.960
a less common condition. Can it be treated arthroscopically?

00:45:54.639 --> 00:45:56.739
Hyperactivation or tightness of the pectoralis

00:45:56.739 --> 00:45:59.219
minor muscle has been proposed as a rare cause

00:45:59.219 --> 00:46:01.920
of shoulder pain, nerve symptoms down the arm,

00:46:02.199 --> 00:46:05.280
or even thoracic outlet -like symptoms. And the

00:46:05.280 --> 00:46:08.019
fix. Arthroscopic or endoscopic release of the

00:46:08.019 --> 00:46:10.340
pectoralis minor tendon from its attachment on

00:46:10.340 --> 00:46:12.940
the coracoid process can be performed. This is

00:46:12.940 --> 00:46:15.019
sometimes done in conjunction with other procedures

00:46:15.019 --> 00:46:17.300
like the Letarjet procedure where it needs to

00:46:17.300 --> 00:46:19.900
be released anyway, or specifically for diagnosed

00:46:19.900 --> 00:46:22.639
pectoralis minor syndrome. It has shown promising

00:46:22.639 --> 00:46:25.489
results in terms of of relieving pain and improving

00:46:25.489 --> 00:46:28.070
shoulder function in the reported cases, although

00:46:28.070 --> 00:46:30.670
it's still relatively uncommon. The surgery is

00:46:30.670 --> 00:46:32.349
typically done with the patient in the beach

00:46:32.349 --> 00:46:36.789
chair position. Moving medially to the sternoclavicular

00:46:36.789 --> 00:46:39.409
joint where your collarbone meets your breastbone.

00:46:40.429 --> 00:46:43.090
What role does arthroscopy play in managing disorders

00:46:43.090 --> 00:46:45.849
there? It seems like a tight space. It is a tight

00:46:45.849 --> 00:46:49.030
space. Sternoclavicular or SC joint arthroscopy

00:46:49.030 --> 00:46:51.670
can be used for diagnosing and sometimes treating

00:46:51.670 --> 00:46:54.190
conditions like persistent pain, inflammation,

00:46:54.409 --> 00:46:56.969
or instability in that joint that haven't responded

00:46:56.969 --> 00:46:59.130
to other treatments. Contraindications. Yes,

00:46:59.150 --> 00:47:00.889
there are certain contraindications that need

00:47:00.889 --> 00:47:02.929
to be carefully considered before proceeding,

00:47:03.250 --> 00:47:05.610
like active infection or severe joint destruction.

00:47:06.150 --> 00:47:08.349
Specific surgical techniques and portal placements

00:47:08.349 --> 00:47:11.309
are used to access the SC joint and it requires

00:47:11.309 --> 00:47:14.329
specialized small instruments. What about instability?

00:47:14.349 --> 00:47:17.289
For SC joint instability, a specific arthroscopic

00:47:17.289 --> 00:47:19.550
technique has been described that aims to preserve

00:47:19.550 --> 00:47:21.889
the important fibrocartilaginous disc within

00:47:21.889 --> 00:47:24.389
the joint while using tending grafts passed through

00:47:24.389 --> 00:47:39.039
bone tunnels to stabilize it. It can be related.

00:47:39.380 --> 00:47:41.500
Surgical treatment for thoracic outlet syndrome,

00:47:41.719 --> 00:47:44.599
or TOS, might be considered if non -operative

00:47:44.599 --> 00:47:47.099
measures fail to provide relief, particularly

00:47:47.099 --> 00:47:49.420
in cases where there are clear neurological symptoms

00:47:49.420 --> 00:47:52.440
or vascular compromise. What's released? Traditionally,

00:47:52.579 --> 00:47:55.260
this involved open surgery, often removing the

00:47:55.260 --> 00:47:58.099
first rib. However, endoscopic techniques have

00:47:58.099 --> 00:48:00.519
been developed as less invasive alternatives

00:48:00.519 --> 00:48:03.000
for releasing structures that can cause compression.

00:48:03.579 --> 00:48:05.500
This might include releasing the scale muscles

00:48:05.500 --> 00:48:08.820
in the neck, scalenectomy or scalenotomy, or

00:48:08.820 --> 00:48:11.079
releasing the pectoralis minor tendon in the

00:48:11.079 --> 00:48:13.239
chest if those are identified as the compressing

00:48:13.239 --> 00:48:15.400
structures. Nerve entrapment around the shoulder

00:48:15.400 --> 00:48:17.960
itself, like when the suprascapular nerve gets

00:48:17.960 --> 00:48:21.079
compressed, can cause significant pain and weakness,

00:48:21.659 --> 00:48:24.039
especially in the rotator cuff muscles it supplies.

00:48:24.519 --> 00:48:27.360
How is that treated endoscopically? The suprascapular

00:48:27.360 --> 00:48:29.639
nerve can get entrapped at two main locations

00:48:29.639 --> 00:48:32.889
as it travels around the scapula. The spinoglenoid

00:48:32.889 --> 00:48:35.449
notch, often by assist from the joint, and the

00:48:35.449 --> 00:48:38.480
superscapular notch under a ligament. Diagnosis.

00:48:39.039 --> 00:48:41.579
Electrodiagnostic tests like nerve conduction

00:48:41.579 --> 00:48:44.699
studies and EMG are crucial to help confirm the

00:48:44.699 --> 00:48:47.360
diagnosis and pinpoint the location of the entrapment.

00:48:47.559 --> 00:48:50.480
And the endoscopic treatment. Endoscopic decompression

00:48:50.480 --> 00:48:52.360
techniques have been developed to release the

00:48:52.360 --> 00:48:54.500
pressure on the nerve at these specific locations.

00:48:55.280 --> 00:48:57.659
This often involves carefully cutting the transverse

00:48:57.659 --> 00:48:59.860
scapular ligament at the suprascapular notch

00:48:59.860 --> 00:49:03.460
or decompressing a cyst at the spinoglenoid notch,

00:49:03.820 --> 00:49:06.519
all done through small portals using endoscopic

00:49:06.519 --> 00:49:09.800
visualization. Medial scapular winging, where

00:49:09.800 --> 00:49:11.780
your shoulder blade sticks out prominently at

00:49:11.780 --> 00:49:14.199
the back, especially when pushing, is often due

00:49:14.199 --> 00:49:16.559
to a problem with the long thoracic nerve, right?

00:49:16.940 --> 00:49:19.119
Can that be addressed endoscopically? Yes. The

00:49:19.119 --> 00:49:21.420
most common etiology for medial scapular winging

00:49:21.420 --> 00:49:24.159
is indeed palsy or injury to the long thoracic

00:49:24.159 --> 00:49:27.039
nerve, which supplies the serratus anterior muscle.

00:49:27.139 --> 00:49:30.179
And the endoscopic approach. Endoscopic decompression

00:49:30.179 --> 00:49:33.000
of the long thoracic nerve along its course looking

00:49:33.000 --> 00:49:35.539
for potential points of compression has been

00:49:35.539 --> 00:49:38.199
explored and has shown potentially good results

00:49:38.199 --> 00:49:40.480
in resolving medial scapular winging in some

00:49:40.480 --> 00:49:43.639
cases. This might be compared to more invasive

00:49:43.639 --> 00:49:46.119
muscle transfer procedures like pectoralis major

00:49:46.119 --> 00:49:48.780
transfer, which is sometimes needed if the nerve

00:49:48.780 --> 00:49:51.440
damage is permanent. The endoscopic approach

00:49:51.440 --> 00:49:53.679
aims to release any compression on the nerve,

00:49:53.980 --> 00:49:56.199
allowing the serratus anterior muscle to hopefully

00:49:56.199 --> 00:49:58.519
recover and function properly again. Finally,

00:49:58.579 --> 00:50:00.320
let's touch on fractures around the shoulder.

00:50:01.019 --> 00:50:03.320
Can arthroscopy assist in their management? It

00:50:03.320 --> 00:50:05.599
seems counterintuitive for broken bones. You

00:50:05.599 --> 00:50:08.119
might think so, but absolutely. Arthroscopy can

00:50:08.119 --> 00:50:10.579
play a valuable role in managing various shoulder

00:50:10.579 --> 00:50:13.380
fractures, often in an assisted capacity. How

00:50:13.380 --> 00:50:16.239
so? For which fractures? Well, for distal clavicular

00:50:16.239 --> 00:50:19.719
fractures, specifically the unstable near type

00:50:19.719 --> 00:50:23.000
2 fractures where ligaments are torn, endoscopic

00:50:23.000 --> 00:50:26.360
or arthroscopic assisted fixation offers a minimally

00:50:26.360 --> 00:50:29.099
invasive approach. It allows for visualizing

00:50:29.099 --> 00:50:31.840
the fracture reduction and placing fixation devices

00:50:31.840 --> 00:50:35.000
like plates or suture buttons with smaller incisions,

00:50:35.320 --> 00:50:37.420
potentially leading to lower complication rates

00:50:37.420 --> 00:50:39.880
compared to open surgery. What about the humerus

00:50:39.880 --> 00:50:42.559
itself? Arthroscopic assisted techniques are

00:50:42.559 --> 00:50:44.639
also commonly used for fractures of the greater

00:50:44.639 --> 00:50:47.260
tuberosity and sometimes the lesser tuberosity.

00:50:47.300 --> 00:50:49.380
Those are the bumps where the rotator cuff tendons

00:50:49.380 --> 00:50:52.300
attach. Arthroscopy helps with accurately reducing

00:50:52.300 --> 00:50:54.599
the fracture fragments, clearing out any blood

00:50:54.599 --> 00:50:56.599
clot, and then fixing them securely in place

00:50:56.599 --> 00:50:59.340
using screws or strong suture anchors. And the

00:50:59.340 --> 00:51:02.199
main ball and socket part. Proximal humeral fractures.

00:51:02.440 --> 00:51:05.300
For proximal humeral fractures involving the

00:51:05.300 --> 00:51:08.500
top of the upper arm bone near the joint, arthroscopic

00:51:08.500 --> 00:51:11.300
assisted reduction and internal fixation, or

00:51:11.300 --> 00:51:14.420
ARF, is an option in selected cases, usually

00:51:14.420 --> 00:51:16.940
simpler two -part or some three -part fractures.

00:51:17.320 --> 00:51:19.820
However, very complex fractures with multiple

00:51:19.820 --> 00:51:22.380
fragments or poor bone quality are generally

00:51:22.380 --> 00:51:24.800
still better treated with an open approach or

00:51:24.800 --> 00:51:27.369
even replacement. Hardware removal. Arthroscopy

00:51:27.369 --> 00:51:29.809
can also be helpful later on to assist in the

00:51:29.809 --> 00:51:32.610
removal of hardware like screws or plates after

00:51:32.610 --> 00:51:34.949
a fracture has healed, especially if the hardware

00:51:34.949 --> 00:51:37.710
is causing impingement or irritation. And glenoid

00:51:37.710 --> 00:51:40.010
fractures, fractures of the socket. Even some

00:51:40.010 --> 00:51:41.869
fractures of the glenoid socket, particularly

00:51:41.869 --> 00:51:44.760
those involving the front rim. bony bankart lesions

00:51:44.760 --> 00:51:47.800
as we discussed earlier, can be managed arthroscopically

00:51:47.800 --> 00:51:50.340
using suture fixation techniques or sometimes

00:51:50.340 --> 00:51:52.820
a bony bankart bridge technique to reconstruct

00:51:52.820 --> 00:51:56.400
the rim. Wow, that really was a deep dive. It's

00:51:56.400 --> 00:51:58.179
incredible really to see the sheer number of

00:51:58.179 --> 00:52:00.980
conditions affecting the shoulder from instability

00:52:00.980 --> 00:52:04.159
and cuff tears to nerve entrapments and even

00:52:04.159 --> 00:52:06.519
fractures that can now be diagnosed and treated

00:52:06.519 --> 00:52:10.260
using these advanced minimally invasive arthroscopic

00:52:10.260 --> 00:52:12.860
and endoscopic techniques. It is quite remarkable.

00:52:12.809 --> 00:52:15.889
And as the author of our source material so optimistically

00:52:15.889 --> 00:52:18.409
pointed out, this field is constantly pushing

00:52:18.409 --> 00:52:21.329
the boundaries of what's possible. The innovation

00:52:21.329 --> 00:52:24.429
is just continuous. We can fully expect even

00:52:24.429 --> 00:52:27.309
more refined techniques, better implants, and

00:52:27.309 --> 00:52:29.869
perhaps even more innovative biological solutions

00:52:29.869 --> 00:52:31.989
to emerge in the years ahead. It's really an

00:52:31.989 --> 00:52:34.210
evolving field. It truly makes you appreciate

00:52:34.210 --> 00:52:37.389
the intricate understanding of anatomy required

00:52:37.389 --> 00:52:40.690
and the incredible ingenuity that goes into developing

00:52:40.690 --> 00:52:42.809
these surgical procedures. and the instruments

00:52:42.809 --> 00:52:45.090
need to perform them through tiny holes. Absolutely.

00:52:45.269 --> 00:52:47.909
Precision is key. So as we wrap things up, here's

00:52:47.909 --> 00:52:50.769
something for you, the listener, to ponder. Given

00:52:50.769 --> 00:52:53.670
this rapid pace of advancement in shoulder arthroscopy

00:52:53.670 --> 00:52:56.469
and endoscopy that we've discussed, what completely

00:52:56.469 --> 00:52:58.909
new frontiers might be explored in the next decade?

00:52:59.409 --> 00:53:02.289
That's a great question. What conditions that

00:53:02.289 --> 00:53:04.650
are currently considered irreparable, maybe like

00:53:04.650 --> 00:53:07.989
severe arthritis in very young people, or massive

00:53:07.989 --> 00:53:10.869
chronic cuff tears with muscle atrophy, might

00:53:10.869 --> 00:53:13.039
become a treatable through these minimally invasive

00:53:13.039 --> 00:53:15.599
approaches, perhaps combined with regenerative

00:53:15.599 --> 00:53:17.880
medicine. The potential is certainly there, maybe

00:53:17.880 --> 00:53:20.000
complex reconstructions we can't even imagine

00:53:20.000 --> 00:53:22.159
yet. It's certainly an exciting future to consider

00:53:22.159 --> 00:53:24.739
for shoulder treatment. Thanks for joining us

00:53:24.739 --> 00:53:25.639
