Another study comparing US and CT arthrography for the diagnosis of anterior talofibular ligament injury showed an accuracy of 61% using US and 71% for CT arthrography [58]. US also has the dynamic capability of stressing the ligament and looking for laxity or frank separation of the injured ligament [1,59]. With regard to interosseous membrane tears, US has a proven sensitivity of 89% and specificity of 94.5% in diagnosing interosseous membrane tears shown at surgery [55,60]. Radiography Stress radiographs can be used to assess ankle instability [1,2]; however, some have questioned their accuracy [3,4]. One study evaluating anterior talofibular ligament injury demonstrated a diagnostic accuracy of 67% for stress radiography [15]. Oae et al [15] compared stress radiography to arthroscopic findings and found the former has an accuracy of 67% for evaluating anterior talofibular ligament injuries. Subtalar stress radiography using forced dorsiflexion and supination [4] or talar rotation [61] can be used to evaluate subtalar laxity. CT Arthrography CT arthrography showed an accuracy of 71% for diagnosing anterior talofibular ligament injury [58]. CT CT CT is not routinely used for the evaluation of ligamentous integrity. Arthrography Arthrography is not routinely used for the evaluation of ligamentous integrity. Image-guided Anesthetic Injection Image-guided anesthetic injection is not routinely used for the evaluation of ligamentous integrity. Bone Scan Bone scan is not routinely used for the evaluation of ligamentous integrity. Chronic Ankle Pain Variant 6: Chronic ankle pain. Ankle radiographs normal or nonspecific, suspected ankle impingement syndrome. Next study. Imaging can also be used to diagnose ankle impingement syndromes, which can occur in the anterolateral, anterior, anteromedial, posteromedial, and posterior aspects of the ankle joint [62-71].
