So here we have a 69 year old shoulder pain,
0:04
limited range of motion and throwing injury of almost two weeks ago
0:10
with this case. We saw that, uh, you know, this, the tendons, uh,
0:15
are basically, uh, we have a full thickness, uh,
0:18
partial with tear at least of the, uh,
0:22
supraspinatus and in infraspinatus tendon. And the other thing we have, uh,
0:26
some of, some of you may have called like a small broad base, uh, suba.
0:30
These fight.
0:31
What you can see here is this little piece of extra bone that arguably is, uh,
0:35
likely probably causing some, uh, uh, impingement, right? And,
0:40
uh, impingement of the shoulder can be divided in,
0:43
divided into two broad categories. What I want you to remember is, uh,
0:48
internal and external impingement, okay? External impingement things causes,
0:52
or you want to think of those, uh, things that, uh, can, uh,
0:55
compress upon the, uh, part of the corco acromial arch. Okay?
1:01
Um, or this, uh, half ring, if you will, uh,
1:04
that can impinge upon the rotator cuff tendons. Okay? And working from a, uh,
1:09
sort of anterior to posterior fashion, we can, uh,
1:12
think about the corco process. We talked about that narrowing earlier. Okay.
1:17
Other things that can cause narrowing, uh, of the, uh,
1:21
this arch or this area are gonna be osteophytes from, uh, uh,
1:25
inferiorly directed osteophytes from, say, severe, uh,
1:28
acromioclavicular joint osteoporosis, other things that can cause, uh,
1:33
impingement, uh, maybe like a thickened cortical, uh, humeral ligament, right?
1:38
Other things are gonna be, uh, a type three, uh, or, uh,
1:43
uh, or hooked acromion, uh, as we see here, in this case,
1:47
a little bit of lateral downsloping as well in the coronal plane.
1:51
Mind you though, some are, uh, some authors including Dr.
1:54
Gentilly from here at UCSD have, have shown that that has really not proven,
1:59
uh, to pan out these, this lateral downsloping in the, uh,
2:03
in the coronal plane. But, uh, for myself, if, uh, my surgeon is still,
2:08
uh, worried about subacromial decom, uh, subacromial, uh,
2:12
impingement or subcoracoid impingement, along those lines, I will offer, uh,
2:17
a dynamic imaging under ultrasound. And again, I'll look for any bunching of,
2:21
of the, uh, tendon otic, typically tendon or partially torn tendon,
2:25
as well as bunching up of the, uh,
2:26
subacromial subdeltoid bursa or even the subcoracoid bursa. Okay?
2:30
And an abrupt release as the patient is ab ducted and a deducting
2:35
their, uh, um, their shoulder to look for that sort of impingement. But here,
2:40
just a nice case of a full thickness, uh, uh,
2:42
tear of the supraspinatus and infraspinatus tendons,
2:45
particularly centered at the, uh, junctional fibers here.
2:49
And some of you nicely measured. The, uh,
2:52
mentioned that the failure is at and near their footprint with arguably a few
2:57
tendonous fibers still remaining
2:59
Intact at their f plates or footprints.
3:01
And then also accurately measured out this, uh, tendon tearing,
3:06
which is, I don't know, about 22 or 23, uh, millimeters.
3:11
And some of you also went and had and measured this, uh, tendon tear, uh,
3:16
accurately for our surgeons, um, in the, uh,
3:21
AP plane as well. And if I, if I had to, I'd probably measure it like this,
3:24
something like that,
3:26
and provide that information to the surgeon along with any, um,
3:31
uh, muscle atrophy of the supraspinatus or involved muscle, uh, uh,
3:36
muscle bellies of the respective tendons that were torn.
3:39
So that's how I read this case. So basically, um, you know,
3:43
full thickness tears of, of these tendons, as well as, uh, some, uh,
3:48
impingement.
3:49
There's also a little bit of tearing and tendonosis of the subscapular tendon.
3:54
But, uh, arguably, obviously the main finding is gonna be this, uh, tendon tear,
3:58
full thickness of, of the, uh, more superior, uh, tendonous, uh, uh,
4:03
more superior rotator cuff tendons.
