Open Fracture Dislocation of the Talus With Partial Talar Extrusion: A Case Report.

We report a case of open talar fracture-dislocation (Gustilo-Anderson type IIIA) associated with a posterior tibial artery injury. The limb was aligned and splinted in the emergency department. In the operating theater, the posterior tibial artery was ligated, the talar neck fracture was reduced, and it was fixed with two Kirschner wires (K-wires). After K-wire removal, the patient underwent rehabilitation to regain function and resumed activities of daily living (ADL). At nine months of follow-up, the patient has a good ankle range of motion (ROM) and a congruent ankle joint but has developed avascular necrosis (AVN) of the talus. This case report highlights the high risk of talus AVN after open talar fracture dislocation. Preservation of the extruded talus and anatomical reduction can maintain ankle alignment, which is essential for arthrodesis in cases of AVN complications.
