Fractures of the inferior or distal femur may be complicated by separation of the condyles, resulting in misalignment of the articular surfaces of the knee joint, or by hemorrhage from the large popliteal artery that runs directly on the posterior surface of the bone. This fracture compromises the blood supply to the leg (an occurrence that should always be considered in knee fractures or dislocations).
Treatment depends on the part of the femur that is fractured. Traction may be useful for femoral shaft fractures because it counteracts the force of the muscle pulling the two separated parts together, and thus may decrease bleeding and pain. Traction should not be used in femoral neck fractures or when there is any other trauma to the leg or pelvis.
