0:00

So our short axis diagram demonstrates

0:03

the dorsal radioulnar ligament.

0:06

It forms the posterior boundary

0:07

of the triangular fibrocartilage.

0:12

These ligaments are actually condensations

0:14

of the triangular fibrocartilage.

0:17

And as we discussed before,

0:19

we have volar ulnocarpal, ulnolunate,

0:23

and ulnotriquetral ligaments.

0:25

We similarly have dorsal ulnocarpal,

0:29

ulnolunate, and dorsal ulnotriquetral ligaments.

0:34

So again, palm up, this is dorsal, Lister's tubercle.

0:35

14 00:00:37,670 --> 00:00:41,340 This is palmar, these are palmar attachments

0:41

coming off the volar radioulnar ligament.

0:43

These are dorsal ligamentous attachments

0:46

coming off the dorsal radioulnar ligament.

0:50

So-called ligamentous-to-ligamentous attachments.

0:54

Boundaries of the triangular fibrocartilage,

0:57

anterior and posterior.
