RESUMO

Fracture-dislocations of the ankle are very frequent in adults. The injuries described by Salter and Harris in developing patients are also common. The authors present a case of tear of the posterior-inferior tibiofibular ligament of the left ankle in a 13 year-old patient. The initial diagnosis with plain X-rays was ankle sprain; however, an ankle CT scan confirmed the patient's injury and he was treated at Morelia's Children's Hospital. CT scan is an extremely useful aid in diagnosing inferior tibiofibular diastasis because the tear of the posterior distal tibiofibular ligament of the ankle mortise is missed in these patients, who initially are diagnosed as having an ankle sprain.
