Q

how do fractures heal?

A

hematoma serves as the basis for a fibrin network, in which granulation tissue grows; capillaries extend into here, and phagocytes clean up as fibroblasts lay down new collagen fibres and chondroblasts form new cartilage; osteoblasts will also work to generate new bone

Q

muscle spasms and healing

A

may occur as local pain and irritation cause strong contractions at the fracture site and may pull the bone fragments further out of position

Q

results of muscle spasms for healing

A

fragments can be out of position, causing angulation, rotation, or overriding of bone pieces; soft tissue damage, bleeding, and inflammation may also occur

Q

ischemia and healing

A

can occur in a cast as edema increases after injury; due to compression, the area may become pale, cold, or numb if the cast is too tight

31
Q

compartment syndrome

A

may develop after fractures when there is excessive inflammation like crushing injuries; increased pressure of fluid within the fascia compresses the nerves and vessels, causing severe pain and ischemia or necrosis; may be aggravated by a cast

32
Q

fat emboli

A

are a risk when fatty marrow escapes from the bone marrow into a vein; can travel to the lungs and cause obstruction, inflammation, and respiratory distress syndrome

33
Q

first indicators of fat embolus

A

behavioral changes, confusion, and disorientation if cerebral; respiratory distress and hypoxia may also occur

34
Q

when are fat emboli’s common

A

in fractures of the pelvis or long bones such as the femur; as well when the fracture site has not been well immobilized during transportation after the injury

35
Q

why may nerve damage occur with fractures?

A

the periosteum may tear

36
Q

failure to heal word

A

nonunion

37
Q

why may failure to heal occur

A

is the bone is not stabilized with the ends closely approximated and aligned

38
Q

long-term residual effects of fractures

A

osteoarthritis or stunted growth

39
Q

signs of a fracture

A

swelling, tenderness, altered sensation, inability to move, crepitus, and pain which may lead to shock (pallor, diaphoresis, hypotension, tachycardia, nausea, and vomiting)

40
Q

crepitus

A

a grating, creaking, cracking, or popping sound that may be heard with fractures

41
Q

tests for fractures

A

X-rays

42
Q

treatment for fractures

A

immediate splinting and immobilization, reductions, or traction

43
Q

reduction

A

can be performed to restore the bones to their normal positions; can be closed or open

44
Q

closed reduction

A

is accomplished by exerting pressure and traction

45
Q

open reduction

A

requires surgery and the use of pins, plates, rods, or screws to fix the fragments in position

46
Q

traction

A

involves the application of force or weight pulling on a limb that is opposed by body weight; the force maintains the alignment of the bones, prevents spasms, and immobilizes the limb

47
Q

dislocation

A

is the separation of two bones at a joint with loss of contact between the articulating surfaces; usually one bone is out of position and one remains normal

48
Q

subluxation

A

if the bone is only partially displaced, with partial loss of contact between the surfaces

49
Q

what might a dislocation be caused by?

A

trauma such as a fall, an underlying disorder like rheumatoid arthritis or other damage like torn ligaments

50
Q

damage of a dislocation

A

there is damage to the soft tissue, the ligaments, nerves, and blood vessels as the bone is pulled away from the joint

51
Q

treatment for dislocation

A

return the original bone to its normal position, immobilization during healing, and therapy to maintain joint mobility

52
Q

sprain

A

is a tear in a ligament and near a tendon

53
Q

avulsion

A

is where the ligaments or tendons are completely separated from their bony attachments

54
Q

signs of sprains

A

tenderness, pain, swelling, and discoloration due to hematoma formation

55
Q

what develops at the site after a sprain?

A

inflammation and then granulation tissue; collagen will also form to create links with the remaining tendon or ligament

56
Q

what is the average healing time for a sprain?

A

6 weeks

57
Q

what may additional stress on a sprain cause?

A

the development of excessive fibrous tissue in the tendon, and thus shortening, less strength, and decreased flexibility at the joint

58
Q

risk factors for injury in fitness

A

inadequate equipment, training, or warm up techniques, as well as more aggressive approaches to sport and failure to allow minor injuries to heal

59
Q

tennis elbow

A

when inflammation develops at the function of the forearm muscle with teh humerus

60
Q

muscle tears

A

are tears along the muscle itself or at points of attachment; occur as a result of direct trauma or overstressing of the muscle; three types (1st, 2nd, 3rd degree)

61
Q

first degree muscle tear

A

usually involves a small percentage of the muscle; pain is mild and does not affect ROM and strength much

62
Q

second degree muscle tear

A

a larger tear that involves much of the muscle, but isn’t a complete tear; pain is severe and the muscle can loss much strength and ROM

63
Q

third degree muscle tear

A

is a complete tear across the width of the muscle; the muscle cannot contract, there will be internal bleeding, and surgery may be required

64
Q

immediate treatment after a muscle tear

A

activity should stop, cold should be applied to stop bleeding, and the limb should be elevated

65
Q

scar tissue and muscle tears

A

scar tissue always forms and will reduce the flexibility and strength of the muscle

66
Q

result of repeated injuries

A

fibrous scar tissue replaces normal structures, hindering mobility and osteoarthritis may develop

67
Q

common causes of tendonitis

A

common swinging motions of the rotator cuff like golfing, tennis, hockey or painting walls

68
Q

repetitive strain injury

A

refers to disorders affecting muscles, tendons, and nerves that develop over a period of time; often is associated with repetitive forceful or precision movements

69
Q

repetitive strain injury damage

A

it interferes with circulation to the area and damages soft tissues

70
Q

risk factors to repetitive strain injury

A

upper body areas, high stress levels, 30-50 age range, and work-related activities

71
Q

signs of repetitive strain injury

A

pain, weakness, numbness, causing disability and interference with sleep

72
Q

what is tendonitis

A

an inflammation of injury of the tendon and sheath

73
Q

carpal tunnel syndrome

A

the median nerve is compressed at the wrist between tendons and the transverse carpal ligaments

74
Q

strain vs sprain

A

a sprain is injury to the ligaments and capsule of a joint and a strain is injury to the muscles or tendons

75
Q

where does the hematoma form?

A

in the medullary canal

76
Q

examples of repetitive strain injury

A

tendonitis or carpal tunnel syndrome

77
Q

treatment for repetitive strain injury

A

rest, cold or heat, NSAIDs, PT and sometimes OT
