Abstract：Objective: To evaluate clinical application of MRI on posterior ankle impingement syndrome. Methods: The MR images of 14 ankle joints in 12 patients clinically confirmed posterior ankle impingement syndrome, were retrospectively analyzed. MRI characteristics and the occurrence rate were respectively summarized according to the sorts of bone and soft tissue impingement. Results: Of all the bone impingement factors, there were 7 cases(7/14, 50%) with os trigonum existence or/and lesion, 7 cases(7/14, 50%) with over length or hyperplasia of posterior process of talus. Of all the soft tissue impingement factors, there were 2 cases(2/14, 14.29%) with the posterior tibiofibular ligament injury, 5 cases(5/14, 35.71%) with posterior ligament injury, 2 cases(2/14, 14.29%) with the ankle ligament injury, 12 cases(12/14, 85.71%) with tenosynovitis of the flexor hallucis longus, 14 cases(14/14, 100%) with tibiotalar and talocalcaneal joint arthritis and synovitis, and 13 cases(13/14, 92.86%) with fat tissue swelling around os trigonum. Conclusion: MRI can be the first choice of examination and can provide objective imaging evidence in diagnosis of posterior ankle impingement syndrome.
