Epiphyseal injury of the lateral condyle related to throwing in a young baseball player: a report of a rare case

Repeated throwing can lead to osteochondral injuries of the elbow in young baseball players with skeletal immaturity.3 Tremendous valgus stress during the late cocking, and acceleration phases of throwing motion produce a distracting force on the ulnar collateral ligament and can lead to avulsion of the medial epicondylar apophysis.6 However, lateral radiocapitellar compression stress and shearing force can lead to osteochondritis dissecans (OCD) of the humeral capitellum.4,13 These osteochondral injuries are well known as throwing-related injuries occurring in skeletally immature baseball players.
