Simultaneous ipsilateral posterior knee and hip dislocations: case report, including a technique for closed reduction of the hip.

In isolation, dislocations of the hip and knee require emergent reduction to minimize the risks of serious complications, including vascular and neurologic injury, osteonecrosis of the femoral head, and loss of motion and function. With simultaneous dislocation of the ipsilateral hip and knee, as in the situation of hip dislocation with concomitant femoral shaft fracture, reduction of the hip may prove difficult because of the inability to control the femoral segment. In this setting, general anesthesia is commonly required. We present the case of a patient who sustained an ipsilateral hip and knee dislocation who underwent closed reduction of the knee in the emergency department but required general anesthesia and the insertion of Schanz pins in the femur to reduce the hip dislocation.
