Q

bone aging

A
  • birth to adult (18-20)- transition from flexible to firm bone
  • adult to elderly (40+):
  • reduction in collagen matrix and calcium salts diminution of bone strength
  • spinal curvature

Q

general considerations with musculoskeletal injuries

A
  • neurological compromise
  • decrease stability
  • muscle spams
22
Q

bone repair cycle

A
  • osteocytes produce osteoblasts
  • deposition of salts
  • increasing strength of matrix
23
Q

inflammatory and degenerative conditions

A
  • bursitis
  • tendonitis
  • arthritis:
  • osteoarthritis- degenerative
  • rheumatoid arthritis- chronic, systemic, progressive, debilitating
  • gout- inflammation of joints produced by accumulation of uric acid crystals

arthritis

A
  • osteoarthritis- degenerative
  • rheumatoid arthritis- chronic, systemic, progressive, debilitating
  • gout- inflammation of joints produced by accumulation of uric acid crystals
25
scene size up
- clues to specific injuries - pelvic fractures or bilateral femur fractures are "load and go" - control major bleeding - history may suggest other injuries
26
initial assessment
- categories of urgency: - life and limb threatening injury - life threatening injury and minor musculoskeletal injury - non life threatening injuries but serious musculoskeletal injuries - non life threatening injuries and only isolated minor musculoskeletal injuries
27
musculoskeletal injury assessment
- rapid trauma assessment -only press on pelvis if no clinical signs of injury are present such as pain - focused H&P- 6 Ps: pain, pallor, paralysis, paresthesia, pressure, pulses - detailed physical exam - ongoing assessment - sports injury considerations
28
detailed exam of extremities
- deformity - contusions - abrasions - penetrations - burns - tenderness - lacerations - swelling - also check PMS*
29
general principles of musculoskeletal injury management
- protecting open wounds - positioning the limb - immobilizing the injury - checking neurovascular function - pulse- palpate and utilize pulse oximetry - motor - sensation
30
splinting devices
- rigid splints - formable splints- vacuum splints, air splints - soft splints - traction splints - other splinting aids- cravats or velcro splints
31
musculoskeletal injury management
- splinting devices - fracture care - joint care - muscular and connective tissue care
32
fracture management: pelvis
- scoop stretcher - pelvic sling device - fluid resuscitation
33
femur fracture management
- traction splints- contraindicated in hip/knee injuries - high force injury - high potential for shock
34
tibia fibula fracture management
- frequently open fractures - cove bone ends with moist dressing - depending on level of fracture, use: - rigid splint - air splint - pillow
35
clavicle fracture management
- most frequently fractured bone in the body - transmitted to 1st and 2nd rib - alert lung injury
36
care for specific joint injuries
- hip - knee - ankle - foot - shoulder - elbow - wrist/hand - finger - be alert for neurological compromise
37
hip fractures
- common in the elderly - may be able to support weight- ability to walk does not rule out fracture - leg often externally rotated - may refer pain to the knee - use other leg for splint - use vacuum mattress if available
38
hip dislocation
- orthopedic emergency - posterior dislocation most common - hip flexed and leg rotated internally - severe pain on attempts to straighten
39
hip dislocation management
- splint in most comfortable position - document sensation and pulse - prompt transport - be alert for associated knee injuries or fractures
40
knee fracture or dislocation
- orthopedic emergency - frequently causes vascular injury - dislocation associated with 50% rate of amputation of leg
41
knee fracture or dislocation management
- obvious dislocation without distal pulse -> apply gentle traction along the long axis of the joint - if gentle traction does not restore the pulse -> splint in place - prompt transport
42
foot or hand injury
- common industrial injury - often disabling - rarely life threatening - splint foot with pillow - splint hand in position of function
43
shoulder injury
- AC separation- sling and swathe - shoulder dislocation- use pillow with sling and swathe - fracture- use sling and swathe
44
elbow injury
- fracture or dislocation may because neurovascular injury - splint in position found - transport promptly
45
rigid splint
-keep hand in position of function
46
air splint
-may be hard to reassess circulation
47
forearm/wrist injury
use a pillow
48
soft and connective tissue injuries
- tendon - ligament - muscle
49
other injury considerations: musculoskeletal injury management
- pediatric musculoskeletal injury - athletic musculoskeletal injury - patient refusals and referral - psychological support
50
tendon
-muscle to bone
51
ligament
-bone to bone
