Abstract
Dislocations of the carpometacarpal (CMC) joints without fracture are rare injuries. They commonly involve the fourth and fifth metacarpals of the dominant hand. Missed and incorrect diagnoses are quite frequent due to subtle clinical and radiological findings. Untreated cases may result in chronic disability due to long term pain and weakness in grip strength. Closed reduction is possible when performed early but can be unstable. We present a rare case of unstable dislocation of fourth and fifth carpometacarpal joints treated by closed reduction and percutaneous pinning.
