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

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.
