Posterolateral dislocation of the ankle without fracture.
We report an unusual case of open posterolateral dislocation of the ankle without fracture following a motor vehicle accident. Most of previously reported cases are posteromedial dislocation. The anterolateral, posterolateral, and purely superior dislocations of the talus make up smaller percentage. The mechanism of this injury appears to be forced eversion of the foot when it is maximally plantar flexed and axially loaded. Our case was treated by manual reduction and percutaneous fixation and anatomical repair of the disrupted deltoid ligament at the time of initial débridement, also achieved good long-term functional and radiographic results.
