Open Ankle Dislocation Without Fractures With Tibialis Posterior Tendon Interposition Through the Interosseous Space

摘要

Open ankle dislocations without fracture are rare injuries. Dislocation or interposition of adjacent tendons are a rare associated feature of ankle fracture-dislocation. We report an extremely unusual case of open ankle dislocation without fracture with concurrent tibialis posterior tendon interposition through the interosseous space that was detected incidentally on computed tomography. We highlight the clinical, radiologic, and intraoperative features to avoid missing similar diagnoses. (C) 2017 by the American College of Foot and Ankle Surgeons. All rights reserved.
