Discussion

Patient had lateral tenderness. Os peroneum looked irregular on plain film. MRI showed edema and irregularity in the sinus tarsi. Tear of the cervical ligament and partial tear of the talocalcaneal interosseous ligament as well as superficial extensor retinaculum. Also sprain of calcaneocuboid capsular ligament (I think the dorsal capsular ligament). Will be treated conservatively and then reimaged if needed.
