Flashcards in Wrist primary structures Deck (13):
What structures form the anatomic snuffbox?
This structure is close to the deep surface of the flexor retinaculum. Median nerve passes through
This is the only major ligament on the dorsal aspect of the wrist
dorsal radiocarpal ligament
This retinaculum prevents tendons from bowstringing as the wrist is extended
This structure crosses the palmar aspect of the wrist, forming part of the carpal tunnel. Prevents bowstringing of tendons during wrist flexion
The flexor retinaculum serves as the attachment point for these muscles
function of the interosseous membrane
stabilizer against axial forces applied at the wrist
This ligament limits ulnar deviation and becomes taut when the wrist is in extremes of extension and flexion.
cartilaginous disc that sits between the ulna, lunate, and triquetrum
Function of TFCC
- provides stability to wrist jt
- connects radius and ulna together
- allows force distribution through wrist
Tunnel of Guyon located between
- hook of hamate
- palmar carpal ligament
- flexor retinaculum
What passes through the tunnel of Guyon?
- ulnar nerve
- ulnar artery
