Anteromedial Subtalar Dislocation

Subtalar dislocation is the simultaneous dislocation of the distal articulations of the talus at both the talocalcaneal and talonavicular joints. It can occur in any direction and can always produce significant deformity. The medial dislocation is most common. Less common presentations are lateral, anterior, and posterior dislocations. These dislocations are associated with osteochondral fractures. Closed reduction and immobilization remain the mainstays of treatment. Proper radiographs and computed tomography scan confirm the postreduction alignment stability of subtalar joints and intraarticular fracture fragments. We report a case of anteromedial subtalar dislocation with no osteochondral fracture fragments in a 25-year-old man.
