Okay, we've been talking about the rotator cuff and
0:02
its six major components: supraspinatus,
0:05
infraspinatus, teres minor, subscapularis,
0:07
coracohumeral ligament, and capsule.
0:10
We've also been talking about the arches,
0:13
the lateral arch underneath the acromion,
0:15
the medial arch underneath the AC joint,
0:18
and the subcoracoid or anterior arch,
0:21
which can damage or injure the lesser tuberosity,
0:24
the biceps, and the subscapularis,
0:27
the forgotten arch.
0:28
But I'm here to talk about the muscular tissue.
0:33
The muscular tissue that dynamically helps
0:36
support the stabilization of the shoulder.
0:39
Whereas the rotator cuff is a static stabilizer.
0:43
The muscles can be divided up into their
0:46
individual anatomic muscles,
0:49
supraspinatus,
0:50
infraspinatus, teres minor, subscapularis.
0:53
But also, the most important,
0:57
distinction in evaluating muscles in the rotator cuff is
1:00
whether they are volumetrically decreased
1:03
and whether they have fatty infiltration.
1:05
And of the two,
1:07
fatty infiltration is worse,
1:09
because if you have fatty infiltration, it's very hard to pull
1:12
that tendon and muscle over and fix it.
1:15
You'll probably shred it.
1:16
So many of those individuals who have severe
1:18
fatty infiltration are not candidates for surgery.
1:22
Now, volumetrically,
1:23
I will admit that that is subjective evaluation,
1:26
for instance,
1:27
this supra and infraspinatus.
1:33
There should be only slits of fat left.
1:36
So I would call this moderate to marked,
1:38
or at least moderate.
1:40
And the amount of fatty infiltration can be
1:42
compared with the trapezius
1:44
to use it as a reference point.
1:46
And I would say there's at least mild,
1:49
perhaps to moderate fatty infiltration.
1:52
But I always try to make that
1:54
distinction for the surgeon.
1:55
Most important is when it's volumetrically severe,
1:59
and even more important than that,
2:01
when the fatty infiltration is severe.
2:04
Those patients are often unsuitable for surgery.
