Let's focus on the ulnar styloid.
0:04
It's a rather strange bird, especially in people
0:08
that have negative ulnar variance, but even in
0:10
other individuals, the styloid may be very long.
0:14
And when it is long, it can impact
0:17
on the adjacent triquetrum, leading
0:19
to ulnotriquetral abutment syndrome.
0:22
Sitting directly atop the ulnar styloid is, in this
0:26
case, a small little brightish area right there.
0:29
Known as the prestyloid recess.
0:32
That recess can be contained as it is here.
0:36
Or it can have a very narrow area of
0:39
communication with the rest of the ulnar capsule.
0:43
Or it can be hourglass-shaped with a free
0:46
communication with the rest of the capsule.
0:49
Or there can be none at all.
0:51
So there's quite a bit of
0:53
variability of this structure.
0:55
Surrounding that tissue is the rather
0:58
bland, somewhat uninteresting, nondescript,
1:02
grayish tissue, which I'm coloring in here,
1:06
representing the ulnomeniscal homolog.
1:10
The slightly brighter tissue, which,
1:13
you know what, I think I'll make white.
1:15
I'll draw white on white.
1:17
That's the capsule.
1:18
So the capsule and the homolog are kind
1:20
of mashed together in one big filler soup.
1:26
Sometimes.
1:27
You'll see a condensed linear structure.
1:30
You might be able to hallucinate
1:32
it here, you might not.
1:33
Perhaps right here, which we might refer
1:36
to as the ulnar collateral ligament.
1:39
Even though it's merely a thickening of
1:42
the ulnar capsule and not physiologically
1:46
that important in the overall stabilization
1:49
of ulnar-sided TFCC wrist structures.
1:52
Then we run into something much more
1:54
substantive, which I'm coloring in light blue.
1:59
And that is the extensor carpi ulnaris subsheath,
2:03
which helps stabilize the extensor carpi ulnaris,
2:07
which is then surrounded by a superficial retinaculum,
2:11
which you see better in the axial projection.
2:14
And that's the story of the ulnar styloid
2:17
and its surrounding peripheral structures.
