Calcaneal Fracture-Dislocation: A Case Report.

Calcaneal fracture-dislocations are rare, high-energy injuries in which the sustentacular fragment typically remains stable, while the posterolateral fragment is displaced laterally. These injuries are frequently associated with additional fractures, ligamentous disruption, or tendon entrapment, and they present considerable diagnostic and surgical challenges. Accurate imaging and meticulous operative planning are essential to restoring hindfoot alignment and function. We report the case of a 45-year-old woman with a calcaneal fracture-dislocation, treated via a medial approach to enable accurate fixation of the posterolateral fragment, potentially reducing the risk of hardware-related tendon irritation.
