Ankle sprains are one of the most common sports-related injuries, and almost all heal without persistent pain or chronic disability.1,2 Two common sources of chronic pain and disability are persistent ankle instability and impingement. 

These entities may occur separately or may coexist. Ankle impingement is defined as entrapment of an anatomic

structure that leads to pain and decreased range of motion of the ankle and can be classified as either soft tissue or osseous.3 

Osseous impingement can result from spur formation along the anterior margin of the distal tibia and talus or as a result of a prominent posterolateral talar process, the os trigonum. 

Soft tissue impingement usually results from scarring and fibrosis associated with synovial, capsular, or ligamentous injury. Soft tissue impingement most often occurs in the anterolateral gutter, the medial ankle, or in the region of the syndesmosis.4 Although radiographs play a role in the eval‎uation of suspected osseous impingement, MR imaging is the most useful imaging modality in eval‎uating suspected soft tissue impingement or in excluding other ankle pathology

such as an osteochondral lesion of the talus. 

MR imaging can reveal evidence of previous ligamentous injury and also can demonstrate thickened synovium, fibrosis, or adjacent reactive soft tissue edema. In the majority of cases, ankle impingement is treated with conservative measures, with surgical debridement via arthroscopy or an open procedure reserved for patients who have refractory symptoms.
