Neglected Hahn-Steinthal fracture in older children

The Hahn-Steinthal fracture or type I fracture of the capitellum humerus is an articular lesion with a frontal fracture line. This fracture is uncommon in the pediatric population but can occur in adolescent and adult. The diagnosis is often missed. The avulsed fragment must be identified on good quality lateral X-rays. We present the case of a 13 years old adolescent who sustained a Hahn-Steinthal fracture of the capitellum, occurring at the time of basketball competition. It was treated operatively by open reduction and internal fixation using screws. At the time of the latest follow up, the result was satisfactory.
