Traction •Process of drawing or pulling apart… •May involve distraction and gliding •Pulling 2 articulating surfaces away from each other  Axis ◦ Traction in line with the long axis of a part Types of Traction 1  Head traction ◦ Traction applied to the head for injuries to the cervical vertebrae, intervertebral discs, nerves or muscles Types of Traction Types of Traction  Weight ◦ Traction application through the use of:  Weights  Pulleys  Ropes 2 Immobilization  Fractures that cannot be immobilized in a cast utilize traction for immobilization Immobilization  The muscles of the limb act as an internal splint to protect the fracture ◦ And provide mechano- receptive input for pain relief 3  Skin traction ◦ Applied with something that encircles the extremity  Used when not more than 5-6 pounds of pull is required  Used for longitudinal pull on the LE  Used for femoral shaft fractures in pediatrics Immobilization  Skeletal traction ◦ Drilling a small hole transversely into the bone and inserting a small diameter wire (1/8 inch) through the bone  Makes it possible for increased tolerances of weight for traction ◦ Femoral shaft on an adult would require 20-30# of pull Immobilization 4 Immobilization  Skeletal Traction ◦ Can be applied to distal areas ◦ Comfortable for patients Immobilization  Skeletal Traction ◦ For femoral fractures it is most commonly applied through t
