Wrist anatomy, short axis, we're going
0:04
to talk about the wimpy, amorphous
0:08
ulnar and radial collateral ligaments.
0:11
The ulnar collateral ligament goes from the styloid
0:14
process of the ulna to the triangular fibrocartilage,
0:19
so it sends fibers into the triangular fibrocartilage,
0:22
but also to the triquetrum and to the pisiform.
0:27
So these structures are part of the ulnar
0:31
collateral ligament complex, including this one.
0:34
Right here.
0:35
The ulnar collateral complex is a rete of structures
0:41
that are condensations of the ulnar capsule.
0:44
They're interposed between the extensor carpi ulnaris
0:48
subsheath and the filler ulno meniscus homolog.
0:52
So often, you don't define the UCL
0:55
as a single isolated structure.
0:58
It's more laminated, as we see here,
1:01
buried within other structures.
1:04
It limits radial deviation.
1:06
The radial collateral ligament goes from the
1:09
styloid of the radius to the scaphoid, but also
1:15
has components that go up to the trapezium or
1:19
greater multangular, and it limits ulnar deviation.
1:23
It's even more wimpy than its ulnar counterpart.
1:26
If we try and cross-reference the radial collateral
1:29
ligament, we can see that the radial collateral
1:30
ligament, you see, it's somewhat difficult to do.
1:32
There's a gray signal intensity structure here, and
1:36
a little black condensation just peripheral to it.
1:40
The same thing is true on the ulnar side.
1:42
If we try and pick out a structure such as
1:44
this one right here, going from the ulnar
1:47
styloid to the triquetrum, we see that there
1:49
are some ill-defined gray tissue structures
1:53
on the T1 and the water-weighted image with a
1:56
condensation of lower signal more peripherally.
2:00
Not a single dominant structure that
2:03
you can pick out, nor is it critical
2:06
to do so for purposes of wrist injury.
