Abstract
A ‘floating hip injury’ is defined as a fracture of the pelvis or acetabulum with a concomitant femur fracture. This combination of injuries is uncommon and estimated to occur once in every 10.000 fractures. This fracture/dislocation pattern occurs commonly in young males involved in high-energy automotive/motorcycle trauma.Floating hip injury caused by car accidents are leading causes of injuries. Over 5.6 million car accidents were reported in the United States in 2012. Of these, over 30,000 of were fatal and another 1.6 million involved other injuries. The hip is prone to several types of injuries (71). Injury to the pelvis occurs in approximately 8-9% percent of what is termed blunt trauma: falls, motor vehicle crashes (cars and motorcycles), bicycle wrecks, and pedestrians being struck by moving vehicles.Acetabulum fractures are more problematic. The integrity of this socket is what keeps the ball of the femur in place. Breaks in this area, depending upon location and severity, may require surgery to stabilize the joint. Dislocations can also occur. Manipulation in the emergency department or the operating room allows for “relocation” of the joint. If there are no associated fractures, further surgery is usually not warranted. Of importance, the blood supply to the “ball joint” of the femur is in this location, so early “relocation” is important.
