Atraumatic peroneal compartment syndrome: An uncommon entity

Peroneus longus ruptures are less common than ruptures of the peroneus brevis muscle and are seldom described in the literature. Ankle inversion injuries causing injury to the distal end of the peroneus longus muscle resulting in lateral compartment syndrome have been documented in the literature. We are presenting an unusual case of peroneal compartment syndrome with no overt ankle injury. The athlete was able to continue physical activity for a week before seeking medical attention. This case necessitates careful attention in assessing non-contact injuries in cases with possible lateral compartment syndrome.
