  1. Applying a Hare Traction Splint (3 of 3) • Connect loops of ankle hitch to end of splint as your partner continues traction. • Carefully tighten ratchet to the point that splint holds adequate traction. • Secure and check support straps. • Assess distal neurovascular function. • Secure the patient and splint to long board for transport.

  2. Applying a Sager Traction Splint (1 of 3) • Expose the injured extremity and check pulse, motor, and sensory function. • Adjust the thigh strap of the splint. • Estimate the proper splint length. • Fit the ankle pads to the patient’s ankle. • Place the splint along the inner thigh.

  3. Applying a Sager Traction Splint (2 of 3) • Secure the ankle harness. • Snug the cable ring against the bottom of the foot. • Pull out the inner shaft of the splint to apply traction.

  4. Applying a Sager Traction Splint (3 of 3) • Secure the limb to the splint. • Secure patient to a long backboard. • Check pulse, motor, and sensory function.

  5. Hazards of Improper Splinting • Compression of nerves, tissues, and blood vessels • Delay in transport of a patient with a life-threatening condition • Reduction of distal circulation • Aggravation of the injury • Injury to tissue, nerves, blood vessels, or muscle

  6. Clavicle and Scapula Injuries • Clavicle is one of the most fractured bones in the body. • Scapula is well protected • Joint between clavicle and scapula is the acromioclavicular (A/C) joint • Splint with a sling and swathe.

  7. A/C Separation With A/C separation, the distal end of the clavicle usually sticks out.

  8. Dislocation of the Shoulder (1 of 3) • Most commonly dislocated large joint • Usually dislocates anteriorly • Is difficult to immobilize

  9. Dislocation of the Shoulder (2 of 3) A patient with a dislocated shoulder will guard the shoulder, trying to protect it by holding the arm in a fixed position away from the chest wall.

  10. Dislocation of the Shoulder (3 of 3) • Splint the joint with a pillow or towel between the arm and the chest wall. • Apply a sling and a swathe.

  11. Fractures of the Humerus • Occurs either proximally, in the midshaft, or distally at the elbow. • Consider applying traction to realign a severely angulated humerus, according to local protocols. • Splint with sling and swathe, supplemented with a padded board splint.

  12. Elbow Injuries • Fractures and dislocations often occur around the elbow. • Injuries to nerves and blood vessels common. • Assess neurovascular function carefully • Realignment may be needed to improve circulation.

  13. Fractures of the Forearm (1 of 2) • Usually involves both radius and ulna • Use a padded board, air, vacuum, or pillow splint.

  14. Fractures of the Forearm (2 of 2) • A fracture of the distal radius produces a characteristic silver fork deformity.

  15. Injuries to the Wrist and Hand • Follow BSI precautions. • Cover all wounds. • Form hand into the position of function. • Place a roller bandage in palm of hand. • Apply padded board splint. • Secure entire length of splint. • Apply a sling and swathe.

  16. Fractures of the Pelvis • May involve life-threatening internal bleeding • Assess pelvis for tenderness. • Stable patients can be secured to a long backboard or scoop stretcher to immobilize isolated fractures of the pelvis.

  17. Assessment of Pelvic Fractures • If there is injury to the bladder or urethra, the patient may have lower abdominal tenderness. • They may have blood in the urine (hematuria) or at the urethral opening.

  18. Stabilizing Pelvic Fractures • A stable patient with a pelvic fracture may be placed on a long board. • If the patient is unstable, consider using a PAGS with the patient stabilized on the long board (consult your local protocols).

  19. Dislocation of the Hip • Hip dislocation requires significant mechanism of injury. • Posterior dislocations lie with hip joint flexed and thigh rotated inward • Anterior dislocations lie with leg extended straight out, and rotated, pointing away from midline. • Splint in position of deformity and transport.

  20. Fractures of the Proximal Femur (1 of 2) • Presents with very characteristic deformity • Fractures from trauma injuries best managed with traction splint or PASG and a backboard. • Isolated fracture in geriatric patients can be managed with long backboard or a scoop stretcher.

  21. Fractures of the Proximal Femur (2 of 2) • A proximal femur fracture will be rotated. • Splint the injured leg to the uninjured leg and secure the patient to a scoop stretcher or backboard.

  22. Femoral Shaft Fractures • Muscle spasms can cause deformity of the limb • Significant amount of blood loss will occur. • Stabilize with traction splint.

  23. Injuries of Knee Ligaments • Knee is very vulnerable to injury. • Patient will complain of pain in the joint and be unable to use the extremity normally. • Splint from hip joint to foot. • Monitor distal neurovascular function.

  24. Dislocation of the Knee • Produces significant deformity • More urgent injury is to the popliteal artery, which is often lacerated or compressed. • Always check distal circulation.

  25. Fractures About the Knee • If there is adequate distal pulse and no significant deformity, splint limb with knee straight. • If there is adequate distal pulse and significant deformity, splint joint in position of deformity. • If pulse is absent below level of injury, contact medical control immediately.

  26. Dislocation of the Patella • Usually dislocates to lateral side. • Produces significant deformity. • Splint in position found. • Support with pillows.

  27. Injuries to the Tibia and Fibula (1 of 2) • Usually, both bones fracture at the same time. • Open fracture of tibia common. • Stabilize with a padded rigid long leg splint or an air splint that extends from the foot to upper thigh.

  28. Injuries to the Tibia and Fibula (2 of 2) Because the tibia is so close to the skin, open fractures are quite common.

  29. Ankle Injuries • Most commonly injured joint • Dress all open wounds. • Assess distal neurovascular function. • Correct any gross deformity by applying gentle longitudinal traction to the heel. • Before releasing traction, apply a splint.

  30. Foot Injuries • Usually occur after a patient falls or jumps. • Immobilize ankle joint and foot. • Leave toes exposed to assess neurovascular function. • Elevate foot 6”. • Also consider possibility of spinal injury from a fall.

  31. Injuries from Falls Frequently after a fall, the force of the injury is transmitted up the legs to the spine, sometimes resulting in a fracture of the lumbar spine.

  32. Foot Stabilization A pillow splint can provide excellent stabilization of the foot.

  33. Review • Skeletal muscle is also referred to as: A. smooth muscle. B. striated muscle. C. autonomic muscle. D. involuntary muscle.

  34. Review Answer: B Rationale: Skeletal muscle, also called striated muscle because of its characteristic stripes (striations), attaches to the bones and usually crosses at least one joint, forming the major muscle mass of the body. This type of muscle is also called voluntary muscle because it is under direct voluntary control of the brain.

  35. Review • Skeletal muscle is also referred to as: • smooth muscle. Rationale: This is found in the walls of most tubular structures, internal organs, and the cardiovascular system. B. striated muscle. Rationale: Correct answer C. autonomic muscle. Rationale: This is not a term associated with the muscles. D. involuntary muscle. Rationale: Involuntary muscle is also called smooth muscle. It is not under voluntary control of the brain.

  36. Review 2. You respond to a soccer game for a 16-year-old male with severe ankle pain. When you deliver him to the hospital, the physician tells you that he suspects a sprain. This means that: A. there is a disruption of the joint and the bone ends are no longer in contact. B. the patient has an incomplete fracture that passes only partway through the bone. C. stretching or tearing of the ligaments with partial or temporary dislocation of the bone ends has occurred. D. the muscles of the ankle have been severely stretched, resulting in displacement of the bones from the joint.

  37. Review Answer: C Rationale: A sprain is a joint injury in which there is both partial or temporary dislocation of the bone ends and partial stretching or tearing of the supporting ligaments. Sprains are typically marked by swelling, pain, and ecchymosis.

  38. Review (1 of 2) 2. You respond to a soccer game for a 16-year-old male with severe ankle pain. When you deliver him to the hospital, the physician tells you that he suspects a sprain. This means that: • there is a disruption of the joint and the bone ends are no longer in contact. Rationale: With a sprain, there will be a partial or temporary dislocation of the bone ends. B. the patient has an incomplete fracture that passes only partway through the bone. Rationale: With a sprain, there is no fracture associated with the injury.

  39. Review (2 of 2) 2. You respond to a soccer game for a 16-year-old male with severe ankle pain. When you deliver him to the hospital, the physician tells you that he suspects a sprain. This means that: C. stretching or tearing of the ligaments with partial or temporary dislocation of the bone ends has occurred. Rationale: Correct answer D. the muscles of the ankle have been severely stretched, resulting in displacement of the bones from the joint. Rationale: A sprain is not an injury to the muscles.

  40. Review 3. A patient injured her knee while riding a bicycle. She is lying on the ground, has her left leg flexed, is in severe pain, and cannot move her leg. Your assessment reveals obvious deformity to her left knee. Distal pulses are present and strong. The MOST appropriate treatment for her injury involves: A. wrapping her entire knee area with a pillow. B. splinting the leg in the position in which it was found. C. straightening her leg and applying two rigid board splints. D. straightening her leg and applying and inflating an air splint.

  41. Review Answer: B Rationale: The patient likely has a dislocated knee. You should immobilize any joint injury in the position in which it was found—especially if distal pulses are present and strong. Attempting to straighten a dislocated joint may cause damage to the nerves and/or vasculature.

  42. Review (1 of 2) 3. A patient injured her knee while riding a bicycle. She is lying on the ground, has her left leg flexed, is in severe pain, and cannot move her leg. Your assessment reveals obvious deformity to her left knee. Distal pulses are present and strong. The MOST appropriate treatment for her injury involves: • wrapping her entire knee area with a pillow. Rationale: Providers can wrap the knee with a pillow to splint it. It is most important to splint the joint in the position it was found. B. splinting the leg in the position in which it was found. Rationale: Correct answer

  43. Review (2 of 2) 3. A patient injured her knee while riding a bicycle. She is lying on the ground, has her left leg flexed, is in severe pain, and cannot move her leg. Your assessment reveals obvious deformity to her left knee. Distal pulses are present and strong. The MOST appropriate treatment for her injury involves: C. straightening her leg and applying two rigid board splints. Rationale: The straightening of a joint injury is contraindicated if the pulses are intact. D. straightening her leg and applying and inflating an air splint. Rationale: Air splints are not effective on joint injuries that are flexed.

  44. Review 4. When treating an open extremity fracture, you should: A. apply a splint and then dress the wound. B. dress the wound before applying a splint. C. irrigate the wound before applying a dressing. D. allow the material that secures the splint to serve as the dressing.

  45. Review Answer: B Rationale: Prior to splinting an open extremity fracture, you should cover the wound with a dry, sterile dressing. This will help control any bleeding and decreases the risk of infection. Irrigating an open fracture should be avoided in the field; this also increases the risk of infection—especially if foreign material is flushed into the wound.

  46. Review 4. When treating an open extremity fracture, you should: • apply a splint and then dress the wound. Rationale: The dressing must come before the splint. B. dress the wound before applying a splint. Rationale: Correct answer C. irrigate the wound before applying a dressing. Rationale: Irrigation of an open fracture in the prehospital setting may increase the chance of infection. D. allow the material that secures the splint to serve as the dressing. Rationale: The wound must be dressed separately from the splint and before splinting is done.

  47. Review 5. Which of the following musculoskeletal injuries has the GREATEST risk for shock due to blood loss? A. Pelvic fracture B. Posterior hip dislocation C. Unilateral femur fracture D. Proximal humerus fracture

  48. Review Answer: A Rationale: The pelvic cavity can accommodate a large volume of blood. Shock in a patient with a pelvic injury is usually due to injury to femoral veins or arteries. Bilateral femur fractures can also cause severe blood loss (up to 1 liter per femur).

  49. Review 5. Which of the following musculoskeletal injuries has the GREATEST risk for shock due to blood loss? • Pelvic fracture Rationale: Correct answer B. Posterior hip dislocation Rationale: Unless the dislocation has injured the vascular system, bleeding will be contained and minimal. C. Unilateral femur fracture Rationale: A unilateral femur fracture can lose 500 -1,500 mL of blood. D. Proximal humerus fracture Rationale: Nerves and blood vessels can be injured and the blood loss could be 500 mL.
