Late Isolated Comminuted Trapezium Fracture with Carpometacarpal Subluxation

Trapezium fracture is the third most commonly occurring fracture in carpal bones, in most author series, but isolated and severely comminuted fracture with carpometacarpal subluxation is extremely rare. We report a case of a 24-year-old man who sustained a closed comminuted trapezium fracture on his left hand, with trapezio-metacarpal subluxation, presented 3 weeks after injury. He was treated by open reduction and fixation by two mini screws and provisional stabilisation of first carpometacarpal joint by two Kirshner wires. Satisfactory outcome was achieved at 6-month follow-up.
