Fractures of the Lateral Process of the Talus With Associated Ankle Instability: A Report of 2 Cases.

Fractures of the lateral process of the talus are uncommon, but often overlooked. They can result in significant functional deficit with residual nonunion and arthritis if not recognized and treated appropriately. We describe 2 cases of such injuries, one with acute recognition and management, and one with delayed diagnosis and nonunion. In both cases, pain from the fracture was accompanied by symptoms of instability requiring simultaneous lateral ligament reconstruction along with fracture fixation. Evaluation of patients with lateral process fractures should include assessment of the lateral ligaments; ankle instability may need to be surgically addressed along with intervention for fracture fixation.
