Abstract

Pediatric ankle fractures are defined as damage to the metaphysis, epiphyseal plate, and epiphysis of the distal tibia and fibula. Although the injury mechanism could be similar, the fracture patterns and treatment of pediatric ankle fractures are different from those of adults. In children, growth plate injuries are more common with a force that would cause sprains in adults because the ligaments are stronger than the growth plate cartilage in children. In the adolescent period, unique fractures, called “transitional fractures”, occur while the physis is closed. For a diagnosis, plain images of the anteroposterior, lateral, and mortise views are essential. Stress radiographs, ultrasound, and magnetic resonance imaging can be used for suspected ligament injuries. The treatment goal is to restore the articular congruity, normal bony alignment, and preserve the epiphyseal plate to ensure normal growth. Pediatric ankle fractures frequently lead to premature physeal arrest, angular deformities, malunion, and posttraumatic arthritis even after anatomic reduction. Treating surgeons should follow-up children for a sufficient time and explain to the caregiver the possible complications before treatment.
