HIDE
PrevNext

0:01

The triangular fibrocartilage. Why spend so much time

0:05

time drilling on to such a tiny little structure?

0:09

Ulnar-sided wrist pain and injuries to the TFC

0:13

and its attachments are probably the most appropriate and

0:17

common indication for advanced imaging, especially MRI.

0:22

The triangular fibrocartilage is complex.

0:26

It's got attachments to the radius,

0:29

to the styloid, to the fovea.

0:31

It's got a superficial peripheral

0:33

attachment layer, a deep attachment

0:35

layer called the ligamentum subcruentum.

0:38

These are injured in people who are young

0:41

with negative ulnar variance posture.

0:43

You might say, well, what's that mean?

0:44

Well, that's why you're going to

0:45

watch the accompanying vignettes.

0:47

What's the ligamentum subcruentum?

0:49

What does variance mean?

0:51

What are some of the other complex attachments?

0:54

What are the ulnocarpal ligaments?

0:56

What's the ulnomeniscal homolog?

0:58

What's the extensor extensor carpi ulnaris subsheath? These are all subjects

1:04

we're going to attack, and you're going to learn about

1:06

in upcoming short quick-hit vignettes.

1:10

Let's have a look.
