Closed reduction and percutaneous pinning of fractures of the proximal phalanx.

This study reports the results of 12 unstable extraarticular fractures of the proximal phalanx treated with transarticular intramedullary Kirschner wires. Early proximal interphalangeal joint motion was allowed and all patients achieved uneventful union, with an average total active motion of 265 degrees. Objective physical assessment revealed one significant flexion contracture, one flexor tendon adhesion and one significant rotational deformity. Excellent results were observed in ten of the 12 patients.
