Closed posterior subtalar dislocation without any associated fracture: a case report and review of the literature.

Pure posterior subtalar dislocation without any medial or lateral displacement of foot is extremely rare and hardly reported in the literature. Such an injury is more likely to be open and associated with fractures of the surrounding bones of the foot. Here we report a rare case of closed pure posterior subtalar dislocation without any associated fracture. We discuss in detail the mechanism of such an injury and highlight the importance of prompt closed reduction and early mobilization to ensure a satisfactory long term outcome.
