The operator fixes the proximal end of the limb with one hand, and holds the distal end with the other hand, then turns the limb in a direction just opposite to the way of displacement for reduction. It is suitable for the oblique fracture with reverse displacement (The two fragments of fracture reversibly overlap because of rotation displacement) which can not be reduced by pulling manipulation only. Before operation, the way of rotation in reverse displacement must be determined according to traumatic mechanism and original X-ray films. The turning back manipulation should be done reversibly. If entanglement of soft tissues occurs during the operation, the way of displacement might be wrongly judged, then the direction of turning back manipulation should be changed. The force of turning should not be vigorous and abrupt lest it should injure the blood vessels and nerves. The manipulation can also relieve incarceration of tissues in the ends of fracture.
