Document Summary

Anular ligament - if dislocation go back into place dislocation. Joints of the hand: the movements take place at the carpal and digit joints. The wrist (carpus), the proximal segment of the hand is a complex of 8 carpal bones. The carpus articulates proximally with the forearm at the wrist joint and distally with 5 metacarpals. The joints formed by the carpus include the wrist (radiocarpal joint and the intercarpal, carpometacarpal, and intermetacarpal joints. Distal end of radius and articular disc with proximal row of carpal bones (except pisiform) Fibrous layer of joint capsule surrounds joint and attaches to distal ends of radius and ulna and proximal row of carpal bones; lined by synovial membrane. Small amount of gliding movement, possible flexion and abduction of hand occur at intercarpal joint. Ulnar collateral ligament attaches to the styloid process of ulna and triquetrum radial collateral ligament attaches to the styloid process of radius and scaphoid.
