Metacarpal and phalangeal osteotomy with miniplate fixation.

We reviewed the results of corrective oseotomies performed with power tools for symptomatic malunions of metacarpal and phalangeal fractures in 10 patients. At an average follow-up of 30 months, all patients had a healed osteotomy with correct alignment and had an average increase of 30 degrees in the flexion arc of the involved digit. We recommend a surgical technique of miniplate fixation over K-wire fixation where possible; it allows precise, intraoperative correction and rigid stabilization. A shortened immobilization time and early motion are significant advantages of plate fixation. However, plates cannot be used across open growth plates or directly over areas of tendon insertion. A careful preoperative plan should always be prepared prior to any corrective osteotomy. Problems such as post-operative tendinous adhesions did not occur, nor did nonunions or delayed unions.
