We're on wrist anatomy.

Extrinsics.
0:04
Yeah, they're hard.
0:05
We're looking at a short axis view with
0:09
the red arrow pointing to the volar radioulnar
0:11
ligament and the yellow arrow pointing
0:14
to the dorsal radioulnar ligament.
0:17
We know we're dorsal with the palm facing
0:19
up because here's Lister's tubercle
0:21
as a potential landmark.
0:24
Now we've said in the past that coming off, not the
0:27
ulna itself, but actually coming off this ligament.
0:30
So it's a ligamentous, the ligamentous origin is the
0:34
volar ulnocarpal ligaments, and the volar ulnolunate
0:39
ligaments, and the volar ulnotriquetral ligaments.
0:43
So injuries of this volar radioulnar
0:46
ligament can be a very destabilizing thing
0:49
because there are multiple volar ligaments
0:52
that come off it.
0:54
And these are actually coming at you, going from
0:57
proximal to distal, attaching to respective areas,
1:01
namely to the scapholunate ligament, to the lunate,
1:06
and to the triquetrum, is where they are headed.
1:09
Now the volar radioulnar ligament is
1:13
involved in stabilization of the radius
1:16
and ulna, specifically in supination.
1:19
And it is particularly compromised when
1:22
there is both a radioulnar volar ligament
1:25
transection and an interosseous membrane injury.
1:28
Let's have a look on MRI.
