Partial articular fractures of the distal humerus commonly involve the capitellum and may extend medially to involve the trochlea. As the complex nature of capitellar fractures has become better appreciated, treatment options have evolved from closed reduction and immobilization and fragment excision to a preference for open reduction and internal fixation. The latter is now recommended to achieve stable anatomic reduction, restore articular congruity, and initiate early motion. More complex fracture patterns require extensile surgical exposures. The fractures are characterized by metaphyseal comminution of the lateral column and have associated ipsilateral radial head fracture. With advanced instrumentation, elbow arthroscopy may be used in the management of these articular fractures. Though limited to level IV evidence, clinical series reporting outcomes following open reduction and internal fixation of fractures of the capitellum, with or without associated injuries, have demonstrated good to excellent functional results in most patients when the injury is limited to the radiocapitellar compartment. Clinically significant osteonecrosis and heterotopic ossification are rare, but mild to moderate posttraumatic osteoarthrosis may be anticipated at midterm follow-up.
