Isolated volar dislocations of the fifth carpometacarpal joints are an uncommon injury. They are classified as ulnopalmar or radiopalmar dislocations. It can be easily missed on standard radiographs. A high degree of suspicion and accurate reduction is pivotal in restoring the functional outcome of the hand. In our case report, a forty year old man presented with ulnopalmar dislocation of the fifth carpometacarpal joint and was treated with open reduction and K wiring. We review the literature and discuss the available methods of management.
