Peroneus longus and brevis rupture in a collegiate athlete.

Peroneal tendon injuries should be considered in the differential diagnosis of lateral ankle pain and instability. The spectrum of injury to the peroneal tendons includes tenosynovitis, tendinitis, subluxation, dislocation and tears. The mechanism, presentation and treatment of isolated peroneal brevis and longus injuries has been described in the literature. This is a case study of a rare combined peroneus brevis and longus injury in a young healthy collegiate athlete.
