Technique for internal fixation of capitellum and lateral trochlea fractures

Abstract

Internal fixation for fractures of the humeral capitellum is a technically challenging procedure. Controversy exists regarding the optimal surgical approach and fixation technique. The benefit of stable fixation of the capitellum fragment is early mobilization. Our preferred technique involves anatomic reduction of the capitellar fragment and fixation with headless screws placed from anterior to posterior. When possible, the surgical exposure employed preserves the lateral ulnar collateral ligament (LUCL) and minimizes disruption of the soft tissues posterior to the capitellum.
