A 32-year-old man presented with simultaneous dorsal dislocations of the index-to-little finger carpometacarpal (CMC) joint with carpal bone fractures. Closed reduction was unsuccessful even after general anesthesia. During open dorsal approach, we found interposed joint capsule in the CMC joints and after removal of the joint capsule open reduction was easily achieved. We placed four Kirschner wires through the CMC joint. Furthermore, the fractured dorsal fragments of the trapezoid and hamate were fixed with mini screw in each. During 1-year followup, the patient showed good recovery and no evidence of posttraumatic arthritic changes in plain X-ray. We recommend to fix the dorsal fragment of the carpal bone with screws as well as the transarticular fixation of the CMC joint in case of concurrent CMC joint fracture-dislocation of all four fingers.
