Athletes' ankle injuries: diagnosis and management.

Ankle injuries are common in the general and athletic populations. These injuries constitute 21% of all sports-related injuries. The wide spectrum of sports-related ankle injuries includes ligamentous injuries, soft-tissue and osseous impingement, osteochondral lesions of the talus, tendon injuries, and fractures. Occult lesions (eg, fractures of the lateral process of the talus, fractures of the anterior process of the calcaneus, fractures of the base of the fifth metatarsal, os trigonum, stress fractures) may be missed on initial physical examination, and patients with such injuries often present to a sports clinic with persistent pain around the ankle. Because of increasing participation in sporting events, health care professionals involved in the care of athletes at all levels must have a thorough understanding of the anatomy, pathophysiology, and initial management of ankle injuries. In this review, we describe the pertinent anatomy, pathology, diagnosis, and treatment of sports-related injuries of the ankle.
