Dislocations of the carpometacarpal (CMC) joints are uncommon and are frequently missed on standard radiographs of the hand. Dislocations could be dorsal or palmar; dorsal dislocations are seen more frequently. Palmar dislocations can be either ulnopalmar or radiopalmar. Stable CMC dislocations could be successfully treated conservatively, while unstable dislocations are mostly treated operatively. The purpose of this report is to present a patient with an isolated ulnopalmar dislocation of the fifth CMC joint, satisfactorily treated with closed reduction and casting.

Introduction: Isolated dislocations of the fifth carpometacarpal joint (CMCJ) are uncommon injuries of the hand that is often missed but can be diagnosed correctly with a high index of suspicion and adequate imaging. Treatment for chronic cases is usually open reduction with temporary fixation using Kirschner wires, but for this case, we used Mini TightRope® as well to allow for early finger exercise. The case presented here is unique because of a delayed dislocation of a CMCJ detected 9 weeks from initial injury which was treated with a novel form of fixation with Mini TightRope®.

Isolated palmar dislocation of the 5 carpometacarpal joint (CMCJ) is a rare injury that can be easily missed and requires a high index of suspicion to detect. We report a case of an initially missed isolated ulnopalmar dislocation of the 5 CMCJ and a summary of other published case reports comparing methods of fixation and outcomes. We conclude that a delay in diagnosis will significantly reduce the chances of successfully managing this injury via closed reduction.

Introduction: Isolated pure dislocation of the fifth carpometacarpal (CMC) joint is a very rare injury and classified depending on displacement of the metacarpal base. This rare injury is often difficult to recognize and is liable to be overlooked. The purpose of this case report is to present a patient with an isolated dislocation of the fifth CMC joint that was satisfactorily treated with closed reduction and ulnar gutter pop slab.

Carpometacarpal (CMC) joint dislocations are uncommon injuries that account for less than 1% of hand injuries. Dorsal dislocations of the CMC joints are more frequent than volar dislocations. Palmar dislocations can be either ulnopalmar or radiopalmar.
