Simultaneous bilateral tibial tuberosity avulsion fractures in adolescence: case report and review of 60 years of literature.

Simultaneous bilateral avulsion fracture of the tibial tuberosity is a rare injury. Since the first reported case in the 1950s only 21 such cases have been reported in literature. When they do occur, it is usually in an adolescent athletic male, generally in the absence of any underlying pathology although rarely it may be associated with an underlying connective tissue disorder. The age range of the injury corresponds to the time of growth plate closure and maturation of the fibro-cartillagenous attachment of the tuberosity. Most of the fractures require open reduction and internal fixation and usually heal well without any significant complications.
