The posterior dislocation of the hip accounts for about 85~90% of traumatic hip dislocations and high energy mechanisms such as traffic accidents may cause them. The traumatic dislocation and fracture-dislocation of the hip are true orthopedic emergencies and it should be considered that a femoral head has poor vascularity and the sciatic nerve is closely located to it. We report on one patient who went through the surgical treatment of the concomitant ipsilateral open fracture of the femoral shaft and hip fracture-dislocation accompanying sciatic nerve injury with the review of the literatures.
