Fracture of the metacarpal head with 180 degrees longitudinal rotation. Case report.

A 61-year old man fell and sustained an intracapital fracture of the 3rd metacarpal bone with an unusual dislocation. Primary radiograph showed 180 degrees longitudinal rotation of the distal fragment. To reduce the fracture the metacarpophalangeal joint was opened and the fracture stabilised. The fracture healed after four weeks, and there was no sign of necrosis at the three month follow up.
