Bilateral Posterior Hip Dislocations with Femoral Head Fractures

SUMMARYAn unusual case of bilateral posterior fracture-dislocation of the hip (Pipkin Type IV) occurred in a 63–year-old man with Pagetʼs disease of the pelvis. Other injuries included a displaced humeral shaft fracture and patellar ligament disruption. Bilateral cemented total hip arthroplasty was performed to avoid the need for prolonged immobilization. Postoperative low-dose irradiation was used because of the risk of heterotopic ossification.
