Volar dislocation of second, third, and fourth carpometacarpal joints: a rare and easily missed diagnosis

摘要

Volar carpometacarpal dislocation is a rare form of hand injury that can be easily missed without applying a high level of suspicion and performing a meticulous examination. In this case report, we present a rare case of compound volar dislocation of the second, third, and fourth carpometacarpal joints in a 40-year-old male. This was managed by closed reduction and the use of a mini external fixator. The patient regained a good range of motion in 6?weeks with no pain. It is important to diagnose and treat this injury in order to avoid the considerable morbidity associated with this condition.
