Abstract
Unilateral pure dislocation of the fifth carpometacarpal joint (CMCJ) is a very rare
injury. We are reporting the second case of an ulnar type of unilateral dislocation
of a fifth CMCJ. Indian salutation (Namaskar) test and radiographs aid in diagnosis.
Closed reduction and internal fixation by K-wires restored the normal anatomic relationships
of the fifth CMC joint. This type of injury is prone to be missed in an emergency
room due to soft tissue swelling, and particular attention should be paid to diagnose
it in polytrauma patients. A review of the literature is presented.
