Bimalleolar Ankle Fracture in an Adolescent With Tillaux Fracture


The purpose of this case report is to present an unusual fracture pattern in an 11-year-old patient characterized by both a predominantly adult fracture type and an exclusively adolescent fracture type. The patient sustained a bimalleolar ankle fracture while sledding. A difficult to detect Tillaux fracture was discovered on preoperative radiograph. The fractures were operatively treated by open reduction and internal fixation. The fracture mechanism is most likely attributed to supination–external rotation injury. The patient thus far has no sign of permanent deformity or disability. This case is unique in that it illustrates an adult fracture type in an adolescent patient. The nearly hidden Tillaux fracture also emphasizes the importance of thorough radiographic examination of any fracture. (Journal of Surgical Orthopaedic Advances 18(2):103–105, 2009)
