Fractured Diaphyseal Tibiofibular Synostosis in an Adolescent Soccer Player

Diaphyseal tibiofibular synostosis is a rare cause of symptomatic shin pain with exertion. In this case, a 14-year-old male soccer player presented with atraumatic right shin pain made worse with running. Computed tomography revealed heterotopic ossification, or synostosis, of the tibial–fibular syndesmosis. The patient's symptoms improved with rest, without the need for operative intervention.
