(1) Skull traction:
Have the patient's hair cut completely, do routine disinfection on the scalp, and let patient lie on his back. Take the point of intersection between skull midline and coronal line joining two mastoid processes as midpoint, 3.5 cm apart from the midpoint in both sides as inserting points of nail tip of icetongs. Under local anesthesia, respectively cut skin incisions about 1 to 2 cm, using a bone drills with safety screw nut to bore at the angle of 45°with the skull into skull lamina (about 4 mm for adults and 3 mm for children). Take care not to injure brain tissues by putting through the skull. Then, put icetong nail into the bone hole, screw and fix it, cover the wound with alcohol gauze, raise the head of bed, tie traction rope to the icetongs and do traction through pulleys. It is suited for fracture dislocation of cervical spine, 4 g for the first and second cervical vertebrae, adding 1 g for each lower vertebra, 4 g for maintenance after reposition.
 
(2) Limb traction:
Do routine disinfection. Under local anesthesia, penetrate a steel pin into olecranon of ulna, or supracondyle of femur, or tubercle of tibia, or calcaneus, put sterile absorbent gauze on the mouth of the pin, and install traction bow, then put the diseased limb on the corresponding traction frame, and do continuous traction. The traction force in this method is greater. It is suited for various unstable fractures in adults. Attention should be paid to the fact that hypertraction might cause separation of broken ends of fracture and influence healing of fracture. It is important to select right penetrating point and master proper penetrating technique for avoiding injury of blood vessels and nerves.

In skeletal traction through the superacondyle of femur, the point at superacondylar part of femur at the level of superior aspect of patella should be selected, and the pin should be inserted from the medial to the lateral. In skeletal traction through the tubercle of tibia, the point at the site on finger-breadth posterior to the tubercle should be selected, and the pin should be inserted from the lateral to the medial. In skeletal traction through the calcaneus, the point at the midpoint of the line connecting the median malleolus and the top of calcaneus should be selected, and the pin should be inserted from the medial to the lateral. In skeletal traction through the olecranon of ulna, the point 2 cm below border of ulna skin should be selected, and the pin should be inserted from the medial to the lateral. Generally, the weight is 4 to 5 kg for traction of upper limb, and 1/10 to 1/6 of the body weight for traction of lower limb.
