Dislocations of the carpometacarpal joint are uncommon because the joint is supported by strong dorsal, volar, and interosseous ligaments and are reinforced by the broad insertions of the wrist flexions and extensors. The cause is usually due to high-speed mechanisms such as motor vehicle crashes, falls, crushes, or clenched fist trauma. If a dislocation occurs, it is usually dorsal with associated fracture. Reduction of dorsal CMC dislocations can be attempted after regional anesthesia with traction and flexion with simultaneous longitudinal pressure on the metacarpal base. Early referral after reduction is needed to determine if further fixation is needed.
