[Fracture of the tibial apophysis--a typical sports injury in adolescents]. / Die Fraktur der Tibia-Apophyse--Eine typische Sportverletzung bei Jugendlichen.

Avulsion fractures of the tibial tuberosity occurred in 7 adolescents. Their ages ranged from 13 to 16 years. With one exception the fracture occurred while the patients were engaged in vigorous sports, particularly soccer and jumping. Open reduction was necessary in 4 patients with dislocation of the tibial tuberosity. Closed reduction was successful in 1 patient while two patients were treated via cast immobilisation. In all patients there was a total disappearance of symptoms within 3 months to 4 years. A classification scheme and the indications for surgery are discussed.
