  3. 3.  Traction is the application of a pulling force to a part of the body ,which can overcome the effect of original deforming force and thus can be used to reduce a fracture or dislocation of a joint.
  4. 4.  Skin traction used extensively in Civil War for fractured femur.  Skeletal traction by a pin through bone introduced by Steinmann and Kirschner  Hippocrates- treated fracture shaft of femur and of leg with the leg straight in extension  Guy de chauliac- introduced continuous isotonic traction in the fracture of femur
  5. 5.  Percival pott- fractured limb should be placed in the position in which muscles are most relaxed  Josiah crosby – isotonic skin traction for treatment of shaft of femur  Thomas Bryant- Braynt’s traction for treatment of fracture shaft of femur in children  Thomas – Thomas splint, used for applying fixed traction
  6. 6.  Malgaigne introduced the 1st effective traction which grasped the bone itself. He used malgaigne’s hooks  Fritz-Steinmann introduced a method of applying skeletal traction to the femur by means of two pins driven into the femoral condyles.  Lorenz-Bohler – ‘The Father of Traumatology’ popularised skeletal traction by means of steinmann pins after he devised Bohler stirrup.
  7. 7.  Safe and dependable way of treating fractures for more than 100 years.  Bone reduced and held by soft tissue.  Less risk of infection at fracture site.  No devascularization.  Allows more joint mobility than plaster
  8. 8.  Skin traction The traction force applied over a large area of skin - Adhesive and Non-adhesive skin tractions  Skeletal traction Applied directly to the bone either by a pin or wire through the bone. (eg- Steinmann pin, denham pin, kirschner wire)
  9. 9.  decrease pain  minimize muscle spasms  reduce, align, and immobilize fractures  reduce deformity  increase space between opposing surfaces
  10. 10.  Costly in terms of hospital stay  Hazards of prolonged bed rest  Thromboembolism  Decubiti  Pneumonia  Requires meticulous nursing care  Can develop contractures
  11. 11.  Bed and Balkan beam  Splints  Slings and padding  Skin traction  Skeletal traction  Stirrups  Cord  Pulleys  Weights
  12. 12.  Countertraction must be used to achieve effective traction.  Countertraction is the force acting the opposite direction.  Usually, the patient's body weight and bed position adjustments supply the needed countertraction.
  13. 13.  Fixed traction- by applying force against a fixed point of body. Ex:  fixed traction by thomas splint.  Roger Anderson well leg traction.
  14. 14.  Sliding traction- by tilting bed so that patient tends to slide in opposite direction to traction force Ex:  Hamilton russell traction  Tulloch Brown traction  Agnes Hunt traction  Perkins traction
  15. 15.  Standard bed has 4-post traction frame  Ideal bed for traction with multiple injuries is adjustable height with Bradford frame  Mattress moves separate from frame
  16. 16.  Bradford frame enables bedpan and linen changes without moving pt  Alternatively bed can be flexible to allow bending at hip or knee
  17. 17.  Ideal knots can be tied with one hand while holding weight.  Easy to tie and untie.  Overhand loop knot will not slip.
  18. 18.  A slip knot tightens under tension.  Up and over, down and over, up and through.
  19. 19.  Clover hitch  Barrel hitch  Reef knot  Half hitch  Two half hitches
  20. 20.  To control the direction of weight  By altering site and by using more than 1 pulley the force exerted by a given weight can be increased  Pulleys of 5-6.25cm diameter with 6cm diameter axles are preferrable
  21. 21. Amount of weight required depends upon  Wt of the appliance  Wt of part of body suspended  Amount of friction present in the system  Mechanical advantage of the system employed for suspension
  22. 22.  The traction force is applied over a large area, this spreads the load and is more comfortable and efficient.  Force applied is transmitted from skin to the bones via superficial fascia, deep fascia and intermuscular septa  For better efficiency the traction force is applied only to the limb distal to the fracture
  23. 23. Skin damage can result from too much of traction force. Maximum weight recommended for skin traction is 6.7 kgs depending on size and weight of the patient
  24. 24.  Adhesive skin traction: Prepare the skin by shaving as well as washing & applying tincture benzoin which protects the skin and acts as an additional adhesive. Avoid placing adhesive strapping over bony prominences, if not, cover them with cotton padding and do the strapping. Leave a loop of 5 cm projecting beyond the distal end of limb to allow movement of fingers and foot.
  25. 25. Non adhesive skin traction  Useful in thin and atrophic skin  Frequent reapplication may be necessary  Attached traction wt. must not be more than 4.5 kgs.
  26. 26.  Temporary management of # of NOF and IT #  Management of # - Femoral shaft of older and hefty children  Undisplaced # of acetabulum  After reduction of dislocation of Hip  To correct minor fixed flexion deformities of hip and knee
  27. 27.  Abrasions and lacerations of skin in the area to which traction is to be applied  Varicose veins, impending gangrene  Dermatitis  When there is marked shortening of the bony fragments as the traction weight required is greater than which can be applied through the skin
  28. 28.  Allergic reactions to adhesive  Excortication of skin  Pressure sores  Common peroneal nerve palsy
  29. 29.  It may be used as a means of reducing or maintaining the reduction of a fracture  It should be reserved for those cases in which skin traction is contraindicated
  30. 30.  Rigid stainless steel pins of varying lengths 4 – 6 mm in diameter. Bohler stirrup is attached to steinmann pin which allows the direction of the traction to be varied without turning the pin in the bone
  31. 31.  Identical to stienmann pin except for a short threaded length in the center . This threaded portion engages the bony cortex and reduce the risk of the pin sliding  Used in cancellous bone like calcaneum and osteoporitic bones
  32. 32.  They are easy to insert and minimize the chance of soft tissue damage and infections  It easily cuts out of the bone if a heavy traction weight is applied  Most commonly used in upper limb eg. Olecranon traction
  33. 33.  Follow regular OT procedures  Use GA or LA  Paint the skin with iodine and spirit  Mount the pin/wire on the hand drill  Hold the limb in same degree of lateral rotation as the normal limb and with ankle at right angles.  Identify the site of insertion and make a stab wound  Hold the pin horizontally at right angles to the long axis of the limb.
  34. 34.  Apply small cotton woolen pads soaked in tincture around the pins to seal the wound  The pin should pass only through skin, SC tissue and bone avoiding muscles and tendons
  35. 35.  Introduction of infection into bone  Distraction at fracture site  Ligamentous damage  Damage to epiphyseal growth plates  Depressed scars

  40. 40.  Direction of traction force can be controlled  No movement between skull and fixation pins  Allows the pt out of bed while traction maintained  Used for c-spine or t- spine fx
  41. 41.  Ring with threaded holes  Allow 1-1.5 cm clearance around head  Place below equator  Spacer discs used to position ring  Central anterior and 2 most posterior
  42. 42.  Two anterior pins  Placed in frontal bone groove  Sup and lat to supraorbital ridge  Two posterior pins  Placed posterior and superior to external ear  Tighten pins to 5-6 inch- pounds with screwdriver
  43. 43.  Traction pull  more anterior for extension  more posterior for flexion  Use same weight as with tong traction
