Retrograde fixation of metacarpal fractures with intramedullary cannulated headless compression screws.

We analyzed the results of 20 unstable metacarpal fractures in 15 patients treated with a cannulated compression screw and no immobilization. All fractures healed within 6 weeks. One patient with multiple fractures and a flexion deficit required arthrolysis of two metacarpophalangeal joints. Another patient had an extension lag. There were no other complications. This fast and easy technique results in good outcomes for unstable metacarpal fractures. The advantages are early active motion without immobilization and stable fixation. Surgical removal of the screw is rarely needed.

LEVEL OF EVIDENCE: IV (therapeutic).
