0:00

Wrist extrinsic ligamentous anatomy focusing on the thumb.

3 00:00:05,710 --> 00:00:08,750 I'm going to skip over the formal collaterals right now.

0:06

5 00:00:08,950 --> 00:00:12,520 for that will be a story that is dedicated to the metacarpals.

0:10

7 00:00:12,740 --> 00:00:15,259 But I want to point out the strongest ligamentous

0:15

attachment of the carpometacarpal junction.

0:19

Which is found on the dorsal aspect of the first CMC.

0:23

And is known as the dorsal radial ligament.

0:27

It's seen right here.

0:28

And it lies just deep

0:31

to the insertion of the abductor pollicis

0:33

longus tendon, which will sit just radial to it.

0:40

This strong ligament is best

0:42

seen in the sagittal projection.

0:44

So let's have a look on MRI.
