Sammarco et al present a case of a 29-year-old man who developed altraumatic anterolateral ankle pain and snapping caused by a hypertrophied peroneus tertius muscle and tendon sliding over the anterolateral talar dome. The patient had operative findings of anterolateral inpingement, which could have contributed to his pain; however, just removing these structures did not relieve the snapping. Postoepratively, the patient's leg was placed in a compression dressing for the first week, followed by a range of motion boot set at 10 degrees of flexion and 10 degrees of extension with 50% weight bearing during the second week and then full weight bearing and physical therapy at week 3.
