Juvenile wakeboarder locks ankle on shore.

This report presents an adolescent wakeboarder with persistent pain after conservative treatment of a Salter Harris type II distal fibular fracture. On physical examination the pain was localised over the anterior inferior tibiofibular ligament. Additional imaging revealed that this syndesmotic impingement was caused by a loose body caught in the syndesmotic area. The loose body was successfully removed from the anterior inferior tibiofibular ligament by anterior ankle arthroscopy. With functional aftertreatment, the patient had resumed full sports activities after 8 weeks. At 1-year follow-up there were no persistent symptoms.
