Q

How do you perform the neurovascular exam?

A

6 P’s
Pain (early sign): worst with passive touch or movement, elevating the limb, or any pressure, stretching increases the pain, and pain meds are not relieving

Paresthesia (early sign): the patient may report it feels like the extremity distal to the fractire feels like its falling asleep “pins and needles”sensation, can they feel you touch their extremity? check unaffected extremity to compare

Pallor: extremity should be pink and have normal capillary refill less than 2 seconds, In compartment syndrome, may appear pale or dusky and have a capillary refill greater than 2 seconds

paralysis: can the patient move the distal extremity from the fracture or has the movement decreased

poikilothermia: occurs when the affected extremity distal from the fracture feels cooler to the touch compared to the unaffected extremity, cannot regulate its temperature

pulselessness: always mark the pulses with a black marker and have a doppler available to monitor the sound of the pulse (this is a late sign)

Q

what is osteoarthritis

A

also called degenerative joint disease (DJD); is a noninflammatory, localized progressive deterioration and loss of cartilage and bone in one or more joints
It is not systemic and it is not an autoimmune disease
As cartilage and the bone beneath the cartilage begin to erode, the joint space narrows andosteophytes(bone spurs) form
Secondary jointinflammationcan occur when joint involvement is severe

Q

post-op care of older adult patient with total hip arthroplasty

A

Use an abduction pillow or splint to prevent adduction after surgery if the patient is very restless or is confused
Keep the patient’s heels off the bed to prevent pressure ulcers
Do not rely on fever as a sign of infection; decreased mental status is a better indicator in the elderly
Move the patient slowly to prevent orthostatic hypotension
Encourage the patient to cough and deep breathe and use the incentive spirometry
As soon as permitted, get the patient up and out of bed
Anticipate the patient’s need for pain relief
Expect a temporary change in mental state immediately after surgery as a result of the anesthetic and unfamiliar sensory stimuli - reorient the patient frequently

Pharmacological:
Antibiotics
Pain management
Wound care
Surgery / debridement

41
Q

define contusions

A

a soft tissue injury produced by blunt force, such as a blow, kick, or fall, causing small blood vessels to rupture and bleed into soft tissues (ecchymosis or bruising)
A hematoma develops from bleeding at the site of impact, leaving a characteristic “black and blue” appearance

42
Q

contusions signs and symptoms

A

Local symptoms includepain, swelling, and possible discoloration

43
Q

contusion management

A

are managed withPRICE therapy, an acronym that refers to protection,rest,ice,compression, andelevation

44
Q

define strain

A

excessive stretching of a muscle or tendon when it is weak or unstable. Strains are sometimes referred to as muscle pulls

45
Q

state the three classifications of strains and explain each

A

First-degree (mild) strain causes mild inflammation but little bleeding. Swelling, ecchymosis (bruising), and tenderness are usually present

Second-degree (moderate) strain involves tearing of the muscle or tendon fibers without complete disruption. Muscle function may be impaired

Third-degree (severe) strain involves a ruptured muscle or tendon with separation of muscle from muscle, tendon from muscle, or tendon from bone. Severe pain and disability result from severe strains and surgery may be needed

46
Q

strain management

A

Cold and heat applications, exercise, activity limitations, NSAIDs and/or muscle relaxants

47
Q

a sprain is

A

excessive stretching of a ligament; caused by a twisting motion or hyperextension (forcible) of a joint
They are also classified according to severity similar to strains

48
Q

sprain management

A

First degree: PRICE therapy

Second degree: immobilization, such as elastic bandage and an air stirrup ankle brace or splint, and partial weight bearing while the tear heals

Third degree: immobilization for 4 to 6 weeks is necessary; and arthroscopic surgery may be done

49
Q

dislocation of the joint occurs when…

A

when the ends of two or more bones are moved away from each other and no longer in anatomic alignment
Subluxed: when the joint is only partially dislocated

50
Q

joint dislocation signs and symptoms

A

Usually, there is pain, decreased mobility, deformity, and deviation in length and rotation of the extremity

51
Q

joint dislocation management

A

Immobilization
Closed reduction of the joint
Pain management

52
Q

a fracture is…

A

a break or disruption in the continuity of a bone that often affects mobility and sensory perception

53
Q

complete fracture

A

the break is through the bone in such a way that the bone is divided into two distinct sections

54
Q

incomplete fracture

A

the fracture is through only part of the bone

55
Q

open (compound) fracture

A

the skin surface over the broken bone is disrupted; so there is an external wound

56
Q

closed (simple) fracture

A

does not extend through the skin and therefore has no visible wound

57
Q

pathologic (spontaneous) fracture

A

occurs after minimal trauma to a bone that has been weakened b disease

58
Q

fatigue (stress) fracture

A

results from excessive strain and stress on the bone

59
Q

compression fracture

A

produced by a loading force applied to the long axis of cancellous bone

60
Q

fractures signs and symptoms

A

Moderate to severe pain
Muscle spasm, paresthesias
Loss of function
Ecchymosis, edema
Deformity, shortening of the extremity
Subcutaneous emphysema, crepitus

61
Q

emergency care of an extremity fracture:

A

Assess ABC’s, and perform a quick head-to-toe assessment
Immobilize the extremity by splinting, including joints above and below injury
Remove the clothing to inspect the affected area
Remove jewelry on the affected extremity in case of swelling
Apply direct pressure if there is bleeding
Keep the patient warm and in a supine position
Assess neurovascular status (check 6 P’s)
Cover any open wounds with a sterile dressing

62
Q

fracture interventions

A

Reduce and immobilize
Traction
Splints or casts
Assess neurovascular and neuromuscular system frequently
PRICE therapy
Pain management
Non-opioid and opioid analgesics with anti-inflammatory drugs and muscle relaxants

Infection
Disuse syndrome
Immobility
Anxiety

64
Q

complications from fractures

A

Acute compartment syndrome
Crush syndrome
Hypovolemic shock

Infection
Chronic complications such as ischemic necrosis or delayed union

65
Q
A
66
Q

acute compartment syndrome (ACS)

A

increased pressure within one or more compartments encased by bone or fascia, which reduces circulation to the area

67
Q

ACS signs and symptoms

A

Sensory perceptiondeficits or paresthesia (usually 1st sign)
Pallor, pulses weaken
Affected area is palpably tense
Pain with movement
Then cyanosis, numbness, paresis, paralysis and necrosis

68
Q

ACS management

A

fasciotomy

69
Q

crush syndrome

A

systemic manifestation of muscle cell damage resulting from pressure or crushing
Systemic manifestations are caused by a traumatic rhabdomyolysis due to muscle reperfusion injury when compressive forces on the tissues are released
This can cause local tissue injury, organ dysfunction, and metabolic abnormalities, including acidosis, hyperkalemia, and hypocalcemia
Prevention of renal failure is important
Alkaline diuresis and mannitol therapy is recommended. Hemodialysis is also recommended for acute renal failure

70
Q

hypovolemic shock

A

from a loss of blood
The bone is very vascular, and bleeding is a risk
In addition, trauma can cut nearby arteries and cause hemorrhage

71
Q

hypovolemic shock management

A

Stabilize the fracture to prevent further bleeding
Restore blood volume and circulation
Provide proper immobilization and protect from further injury
Pain relief

72
Q

fat embolism syndrome (FES)

A

fat globules are released from the yellow bone marrow into the bloodstream causing clots

73
Q

FES signs and symptoms

A

Hypoxemia, dyspnea with tachypnea
Decreased LOC, agitation, confusion
Petechial rash (late sign)

74
Q

FES management

A

Reduce the risk with immobilization and maintenance of fluid and electrolytes
Supportive care with mechanical ventilation, vasopressors and corticosteroids

75
Q

venous thromboembolism (VTE)

A

includes deep vein thrombosis (DVT) and pulmonary embolism (PE) and its major complications
It is the most common complication of lower extremity surgery or trauma and the most often fatal complication of musculoskeletal surgery

76
Q

VTE risk factors

A

Cancer or chemotherapy, surgical procedures > 30 minutes, smoking, obesity, heart disease, prolonged immobility, oral contraceptives, history of VTE, older adults

77
Q

Type of infections and causes

A

Osteomyelitis: is most common with open fractures in which skin integrity is lost and after surgical repair of a fracture
Wound infections are the most common type of infection resulting from orthopedic trauma
They range from superficial skin infections to deep wound abscesses
Infection can also be caused by implanted hardware used to repair a fracture surgically, such as pins, plates, or rods

78
Q

avascular necrosis

A

blood supply to the bone is disrupted causing decreased perfusion and death of bone tissue
This problem is most often a complication of hip fractures or any fracture in which there is displacement of bone. Surgical repair of fractures also can cause necrosis because the hardware can interfere with circulation

79
Q

delayed union

A

is a fracture that has not healed within 6 months of injury
Some fractures never achieve union; that is, they never completely heal
Malunion: when the bone heals incorrectly

80
Q

amputations

A

is the removal of a part of the body
Amputation is considered only after other interventions have not restored circulation, sometimes referred to as limb salvage procedures
The circulatory status of the limb is evaluated through physical examination and diagnostic studies. Muscle and skin perfusion is important for healing

81
Q

amputations signs and symptoms

A

Poor circulation (6 Ps!)
Discolored skin
Edema
Ulcers
Necrosis
Hair distribution

82
Q

amputation diagnostic test

A

Ankle-brachial index (ABI)
Doppler ultrasonography

Transcutaneous oxygen pressure (TcPO2)

83
Q

amputation interventions

A

Monitor for signs of sufficient tissue perfusion
Monitor and control for bleeding and infection
Control edema though compression dressings
Prevent joint contractures
Pain management
Analgesics + beta blockers, antiepileptic drugs, antispasmodics, antidepressants
Collaborate with rehab to improve ambulation and self-care
Psychological and behavioral health

84
Q

complications from amputations

A

Hemorrhage
Infection
Phantom limb pain
Flexion contractures
Skin breakdown

85
Q

phantom limb pain (PLP)

A

when sensation is felt in the amputated part and it persists and is unpleasant or painful
Often described as intense burning, crushing, cramping, or that the part is in a distorted or uncomfortable position
For most patients, the pain is triggered by touching the residual limb or by temperature or barometric pressure changes, concurrent illness, fatigue, anxiety, or stress

86
Q

PLP management

A

IV infusions of calcitonin (Miacalcin, Calcimar) during the week after amputation can reduce phantom limb pain

87
Q

flexion contractures

A

occur usually in the hip or knee in patients with amputations of the lower extremity
This complication must be avoided so that the patient can ambulate with a prosthetic device
Proper positioning and active range-of-motion exercises help prevent this complication
