Ultrasound examination of ankle injuries in children.

Abstract

Fourteen children with ankle injuries, an open tibia and fibula physis, and negative radiographs had ultrasonography of their injured ankles. Five had an anterior talofibular ligament injury and five had an anterior tibiofibular ligament injury. Four had normal ultrasound examinations. Only two had a physeal injury, both of which were associated with a ligament injury. Eleven children had only lateral ankle tenderness. Ultrasound of these 11 revealed ligamentous injuries, normal examinations, and the two physeal injuries. Ligamentous injury was not associated with other tenderness patterns.
