The adolescent Tillaux fracture is an avulsion fracture of the anterolateral corner of the distal tibial epiphysis caused by external rotation of the foot. This type of fracture occurs during epiphyseal fusion in adolescence. A difficult to detect Tillaux fracture was discovered on a preoperative radiograph, such fractures have rarely been reported to accompany a predominantly adult-type ankle fracture. Especially, to the best of our knowledge, no case of a trimalleolar ankle fracture in an adolescent with a Tillaux fracture has been reported. Thus, we present a case of a trimalleolar ankle fracture in a 15-year-old adolescent with a Tillaux fracture who was successfully treated surgically.
