Isolated Adult Tillaux Fracture Associated With Volkmann Fracture-A Unique Combination of Injuries: Report of Two Cases and Review of the Literature.

Abstract

Avulsion fractures of the anterior inferior tibiofibular ligament from its tibial attachment, Tillaux fractures, are usually seen in adolescents during the interval of the distal tibial epiphyseal closure. However, this pattern of fracture is rare in adult patients, because the ligaments will usually fail before the bone fails. Avulsion fracture of the posterior inferior tibiofibular ligament from its tibial attachment, Volkmann fracture, is the posterolateral counterpart of a similar injury. In the present study, the cases of 2 adult patients with simultaneous Tillaux and Volkmann fractures are reported and the mechanism of injury, diagnosis, and treatment discussed. This fracture pattern is extremely rare and, to the best of our knowledge, has not been previously reported.
