TY - JOUR T1 - Acute Osteochondral Shear Fracture of the Capitellum in a Twelve-Year-Old PatientA Case Report AU - Sodl, Jeffrey F. AU - Ricchetti, Eric T. AU - Huffman, G. Russell Y1 - 2008/03/01 N1 - 10.2106/JBJS.G.00017 JO - The Journal of Bone & Joint Surgery SP - 629 EP - 633 VL - 90 IS - 3 N2 - The exact prevalence of radiocapitellar joint injuries in adolescents is unknown. The most common elbow disorders in young athletes include overuse injuries, such as osteochondritis dissecans and Panner disease. Fractures of the capitellum and radial neck can also occur in this age group as a result of direct trauma. Marion and Faysse reported only one capitellar fracture in a series of 2,000 elbow fractures in children1. Two fracture patterns of the capitellum have traditionally been described. The first type, a coronal shear fracture often referred to as the Hahn-Steinthal fracture, usually contains a large portion of cancellous bone from the lateral humeral condyle and may include the lateral crista of the trochlea as well2,3. The second type, a pure articular fracture called the Kocher-Lorenz fracture, has little or no subchondral bone attached to the fragment4,5 and is rarely seen in children6.
