title: Ankle impingement syndromes: a review of etiology and related implications.
abstract: Ankle injuries are common occurrences in athletics involving and requiring extreme ranges of motion. Ankle sprains specifically occur with a 1 in 10,000 person rate in active individuals each day. If trauma is repetitive, the ankle structures have potential to experience secondary injury and dysfunction. Included in this category of dysfunction are both anterior and posterior ankle impingement syndromes where disruption of the bony structures, joint capsule, ligaments, and tendons typically occurs. Ankle impingement is described as ankle pain that occurs during athletic activity, with recurrent, extreme dorsiflexion or plantar flexion with the joint under a load. Ankle impingements can be classified according to what structures become involved both anteriorly and posteriorly. Osseous impingement, soft tissue impingement, impingement of the distal fascicle of anterior inferior tibiofibular ligament, and meniscoid lesions are all documented causes of ankle impingement. These changes tend to be brought about and exacerbated by extreme ranges of motion. Understanding various impingement types will better enable the clinician to prevent, identify, treat, and rehabilitate affected ankles. Acknowledging activities that predispose to ankle impingement syndrome will enhance prevention and recovery processes. Description of ankle impingement etiology and pathology is the objective of the current review.
