*<unk> s are used for temporary fixation during some operations. After definitive fixation they are then removed. The pins are usually removed four weeks post operation. * They can be used for definitive fixation if the fracture fragments are small (e.g. wrist fractures and hand injuries). In some settings they can be used for intramedullary fixation of bones such as the ulna. * Tension band wiring is a technique in which the bone fragments are transfixed by<unk> s which are then also used as an anchor for a loop of flexible<unk> . As the loop is tightened the bone fragments are compressed together. Fractures of the kneecap and the olecranon process of the elbow are commonly treated by this method. *<unk>  is passed through the skin then transversely through the bone and out the other side of the limb. The<unk>  is then attached to some form of traction so that the pull is applied directly to bone. In traction of the femur for example, the protruding ends of the<unk>  are fixed to the legs of a horseshoe shaped frame which maintains tension in the<unk>  while the crook of the horseshoe is attached via line and pulleys to weights which maintain the traction. * They can be used for temporary joint immobilization. *<unk> s can be used to guide cannulated screws to a precise location.
