Acute ulnar carpometacarpal dislocations. Can it be treated conservatively? A review of four cases.

Dislocations of the ulnar carpometacarpal (CMC) joints are uncommon injuries. Initially, the injury is often overlooked or not found as an injury at all. Most cases presented in the literature advocate reduction with operative stabilization to prevent secondary dislocation. We present four cases of acute fourth and fifth CMC dislocations treated conservatively by closed reduction and splint immobilization.
