Simultaneous closed dislocations of the metacarpophalangeal joints of the index, long, and ring fingers: a case report.

A patient with simultaneous closed dislocation of the metacarpophalangeal joints of the index, long, and ring fingers and an ipsilateral fracture of the radius with an associated fracture-dislocation of the distal radioulnar joint is presented. This is the first such case to be described. The mechanism of injury was a fall on an outstretched hand. The dislocations of the metacarpophalangeal joints were successfully reduced by open relocation through dorsal approaches. The fractured radius was treated with open reduction and plate fixation. The patient was placed in a dorsal extension block splint after surgery, and active motion was encouraged. Eleven months later, the patient could make a full fist and extend all fingers. Grip strength was 110 pounds in the right hand, and 100 pounds in the injured left hand.
