Osteochondral fracture of the talar dome is an uncommon lesion occurring after ankle inversion and tearing of the lateral ligaments.

Symptoms may persist for many months if accurate radiographic diagnosis is delayed. Prompt arthrotomy is indicated to prevent post-traumatic arthritis of the ankle joint.
