This exhibit will: 1. Review the definition and classification of the various impingement syndromes about the ankle joint. 2. Review the pertinent ligamentous anatomy of the ankle joint. 3. Provide an overview of the clinical presentations, common causes, and imaging manifestations of impingement at and about the ankle joint. Main teaching points: 1. The ankle impingement syndromes are caused by entrapment of an anatomic structure of the ankle joint by pathologic soft tissue or bony conditions leading to chronic pain and restricted mobility. 2. MRI is best used to assess the soft tissue etiologies of impingement and radiography can be used to evaluate for osseous abnormalities.
