Posteromedial dislocation of the elbow with associated intraarticular entrapment of the lateral epicondyle.

Abstract

Traumatic elbow dislocation is relatively common in adolescents. Most cases occur in a posterolateral direction. Elbow dislocation is often accompanied by fractures, most frequently of the medial epicondyle. The authors report a rare case of posteromedial elbow dislocation and associated fracture of the lateral humeral epicondyle trapped within the joint.
