Transcript:

00:00:00:22 - 00:00:03:22
There's a 68-year-old male. 68.

00:00:04:05 - 00:00:05:29
Pain for a month.

00:00:05:29 - 00:00:08:01
Do 68-year-olds get instability?

00:00:08:01 - 00:00:10:13
Are they moving their arm enough to get it?

00:00:10:13 - 00:00:12:01
Of course, they are.

00:00:12:01 - 00:00:15:01
This patient plays golf and he's got pain

00:00:15:04 - 00:00:17:25
in the mid to latter portion of his golf swing,

00:00:17:25 - 00:00:20:00
and he's got good reason for it.

00:00:20:00 - 00:00:22:25
The first thing you do is you look at the anatomy on T1-weighted

00:00:22:25 - 00:00:26:11
bone fat weighted sequence.

00:00:26:17 - 00:00:29:18
and you see the patient has a goatee or a goat-beard deformity.

00:00:29:24 - 00:00:32:09
There's glenohumeral arthropathy.

00:00:32:09 - 00:00:37:09
This patient complains of inability to complete his golf swing.

00:00:37:09 - 00:00:39:09
His back swing is diminished.

00:00:39:09 - 00:00:40:26
His follow-through is diminished.

00:00:40:26 - 00:00:44:24
So in some respects, he's got decreased range of motion. Why?

00:00:45:24 - 00:00:48:24
This spur is inhibiting his range of motion.

00:00:49:17 - 00:00:52:10
So, it is not uncommon

00:00:52:10 - 00:00:55:11
for you to hear, especially in middle-aged patients

00:00:55:27 - 00:00:58:25
or in individuals who are young and are guarding the shoulder,

00:00:58:25 - 00:01:02:21
that even though they have instability, they have decreased range of motion.

00:01:03:18 - 00:01:08:00
This is a very counterintuitive clinical concept.

00:01:08:28 - 00:01:11:27
Let's look at the sequela

00:01:11:27 - 00:01:17:01
of this patient's instability on MR imaging.
