Q

Self-Healing Nature of Bone

A
  • Break causes soft tissue swelling and a blood clot in the fracture area
  • Interruption of blood supply causes the bone section to die
  • Cells further from fracture divide rapidly forming tissue that heals the fracture and develops into new bone

Q

Injury to Bones and Connective Tissue

A

• Not all injuries can be confirmed as a fracture in the field
• Splinting an extremity with a
suspected fracture helps prevent blood loss from bone tissues

Q

Think About It: Musculoskeletal

A
  • Do my patient’s musculoskeletal injuries add up to serious multiple trauma?
  • Does my patient have circulation, sensation, and motor function distal to the suspected fracture or dislocation?

Q

Advantages of Splinting

A
  • Minimizes movement of disrupted joints and broken bone ends
  • Prevents additional injury to soft tissues (nerves, arteries, veins, muscles)
  • Decreases pain
  • Minimizes blood loss
  • Can prevent a closed fracture from becoming an open fracture

Q

Principles of Splinting

A
  • Care for life-threatening problems first
  • Expose injury site
  • Assess distal CSM
  • Align long-bone injuries to anatomical position
  • Do not push protruding bones back into place
  • Immobilize both injury site and adjacent joints
  • Choose splinting method based on severity of condition and priority decision
  • Apply splint before moving patient to stretcher
  • Pad voids

Q

Realigning Deformed Extremity

A

• Assists in restoring effective circulation to extremity and to fit it to splint
• If not realigned, splint may be ineffective, causing increased
pain and possible further injury
• If not realigned, increased chance of nerves, arteries, and veins being compromised
• Increased pain is only momentary

Q

Hazards of Splinting

A
  • “Splinting patient to death”—splinting before life-threatening conditions addressed
  • Not ensuring ABC’s
  • Too tight—compresses soft tissues
  • Too loose—allows too much movement
  • Splinting in deformed position

41
Q

Chapter Review: Musculoskeletal Trauma

A
  • Bones bleed. Fractures cause blood loss within the bone.
  • Splinting of long bone fractures involves immobilizing adjacent joints.
  • Splinting protects the patient from further injury.
42
Q

Chapter Review: Musculoskeletal Trauma

A
  • You may need to be creative while splinting. There are many correct ways to splint the same extremity.
  • Injuries to bones and joints should be splinted prior to moving the patient.
43
Q

Chapter Review: Musculoskeletal Trauma

A

• If patient has multiple trauma or appears to have shock do not waste time splinting individual fractures. Place patient on long
spine board and secure limbs to board. Splint individual fractures en route if time and priorities allow.

44
Q

Remember: Musculoskeletal Trauma

A

• Bones, joints, muscles, cartilage, tendons, and ligaments make up the musculoskeletal system.
• Bones provide the body with structure, store metabolic materials, and produce red
blood. Joints are the places where bones articulate to create movement.

45
Q

Remember: Musculoskeletal Trauma

A

• Fractures, dislocations, sprains, and strains are musculoskeletal injuries that are caused by direct force, indirect force, and twisting force. Injuries should be splinted prior to moving the patient.

46
Q

Remember: Musculoskeletal Trauma

A
  • A closed extremity injury is one in which the skin has not been broken. An open extremity injury is one in which the skin has been broken.
  • Pelvic fractures and femoral shaft fractures often indicate more severe internal injuries.
47
Q

Remember: Musculoskeletal Trauma

A

• EMTs must learn specific techniques for immobilizing particular injuries but at the
same time must foster creativity while applying the general rules of splinting.

48
Q

Questions to Consider: Musculoskeletal Trauma

A
  • Have I fully addressed life threats and maintained my priorities even in the presence of a grossly deformed extremity?
  • Does the patient have an injury that requires splinting?
49
Q

Questions to Consider: Musculoskeletal Trauma

A
  • Does the patient have multiple fractures, multiple trauma, or shock?
  • Does the patient have adequate CSM distal to the musculoskeletal injury?
  • Should I align the angulated extremity fracture?
50
Q

Critical Thinking: Musculoskeletal Trauma

A

• Patients who suffer fractures can be in extreme pain. Pain can cause anxiety and elevated pulse rates. How could you
differentiate between a patient with a rapid pulse and anxiety from pain versus a patient with rapid pulse and anxiety from
shock?

splint to stop any further injury from occurring

splinting the pt to death

A

focus on the real problem not the traumatic injury

airway - then bag
RTA
orthopedic injury will not kill the pt

fell or hear crepitus

swelling, bruising, eposes ends, here /blook vessel, compartment syndrome

review splinting hazards

wrap in the direction of venous blood flow

A

can check PMS with cap refill

74
Q

if no pulse in the extremity, realign to get it back in place

A

.

75
Q

fracture - splint - immobilize adjacent bone ends

joint below and the joint above

A

.

76
Q

traction splint

A

mid shaft femur - only thing you can use a traction splint on

measure on the good leg
muscles go into tetany - constant contraction
jagged bone ends start cutting tissue

same length as good leg or pt tells you they have some relief

never roll onto the injured side

make sure we know who you use it for mid shaft femur fracture for

77
Q

shoulder girdle

A

sling and swath

78
Q

pelvic injuries

A

tie legs together

79
Q

hip fracture / dislocation

A

most hip fracture are actually fractures of the proximal femur

neck of the femur

seldom a fracture to the socket joint

80
Q

posterior - turned in

anterior - turned out
