title: Distraction-fixation in the primary treatment of metacarpal bone loss.
abstract: Nine patients seen in civilian practice with severe open injuries of the hand, including loss of portions of some or all of the metacarpals, were treated by primary restoration of metacarpal length and alignment by distraction-fixation with the use of transverse intermetacarpal Kirschner wires. An external fixation device was added in two of the nine patients. Severe associated soft tissue injuries were present in all but one patient. Two injuries were caused by firearms, and the other seven by heavy machinery. Contractures of the joints were prevented by the use of a second set of wires to position the metacarpophalangeal joints in 70 degrees of flexion and the first metacarpal in abduction and pronation. Staged closure of wounds by local or distant flaps and secondary reconstructions by bone, nerve, and tendon grafts or transfers were necessary in all and required an average of almost 2 years until treatment was completed. All except the one child and the one most recently injured patient have returned to employment or vocational retraining. Follow-up was 24 to 78 months from injury.
