Fractures of the lateral process of the talus

A retrospective review of nine patients with fractures of the lateral process of the talus indicates that a substantial portion of patients will have persistent symptoms if the fracture is not diagnosed and appropriately treated soon after the injury. When a patient is evaluated for the symptoms of a "sprained ankle," these fractures are often overlooked on the initial roentgenograms. If untreated, these fractures often fail to heal, and persistent pain over the lateral aspect of the ankle following an inversion injury should be investigated for the possibility of this diagnosis. Prompt treatment of acute fractures appears to lead to the best result. Nondisplaced fractures heal well in a short-leg cast, with six weeks of immobilization. Large displaced fracture fragments require surgical treatment: single large fragments should be reduced and internally fixed, and large comminuted fragments should be excised.
