Bone edema at the lateral dorsal aspect of the lateral malleolus. Hemorrhage around the peroneal tendons in the retromalleolar groove. The longus tendon shows lateral subluxation.

Small cortical avulsion at the dorsal lateral malleolus, corresponding to the bony insertion of the SPR.
Case Discussion
This type of injury may lead to chronic peroneal tendon instability and subluxation.
