Fractures of capitellum and trochlea.

The principles of management of capitellar and trochlear fractures are similar to any other intra-articular fracture. Accurate anatomic reduction, rigid internal fixation, and early mobilization of the elbow are prerequisites for a good functional result. Small fragments with minimal subchondral bone, not amenable to rigid internal fixation, are best treated by surgical resection. This article outlines the diagnosis, treatment, controversies, postoperative results, and complications of these rare elbow fractures.
