Bilateral femoral head fracture with posterior hip dislocation.

Bilateral posterior hip dislocations with femoral head fractures are rare. We report the case of a 71-year-old woman who was an unrestrained driver involved in a head-on motor vehicle collision. The right hip was stable after reduction, while the left hip was felt to be unstable. Bilateral bipolar endoprostheses were inserted via standard posterior approaches. Fracture fragments composed approximately 35% of the femoral head in both hips. We believe an elderly polytrauma patient with a significant femoral head fracture may benefit from primary arthroplasty as a treatment option, especially in cases of bilateral injury.
