摘要
Simultaneous fracture/dislocation of the thumb carpometacarpal （CMC）joint and dislocation of the metacarpophalangeal （MCP） joint is considered as a rare injury pattern. We report an unusual case of dorsal disloca- tion of MCP joint of the thumb associated with extraarticular fracture of the base of the first metacarpal in a 28-year-old man. The dislocation of MCP joint had been missed during initial presentation at a peripheral centre. The patient made an uneventful recovery following open reduction and fixa- tion with 1.25 mm Kirschner wire of the MCP joint along with repair of the ulnar collateral ligament. This injury pat- tern has not been previously reported to the best of our knowledge in the English-language based medical literature.
