Unit 2 -MSK Flashcards
1
Q
Fracture
A
disruption or break of the structure of a bone. When force is greater then bone strength.
2
Q
Classification of a fracture depend on
A
What bone, where, how many fragments, what direction.
Open or closed, complete or incomplete, direct, displaced or not
3
Q
Open fracture
A
open breaks through the skin (highest risk for infection)
4
Q
Closed fracture
A
The bone breaks but it does not go through the skin
5
Q
Displaced fracture
A
The bone breaks and both ends are no longer straight (no longer togther, separated)
6
Q
Non-displaced fracture
A
The fracture is in one spot and the bone is still straight
7
Q
complete break
A
all the way through the bone
8
Q
incomplete break
A
only through part of the bone
9
Q
Directions a bone can be broken
A
linear, oblique, transverse, longitudinal, spiral, greenstick, comminuted, pathological, stress
10
Q
What is a stress fracture
A
often runners will get this, this happens in small bones that are having to much stress put on them
11
Q
when do people typically get spiral fractures
A
from a fall, sport, twist, trauma, accident
12
Q
transverse fracture
A
across the shaft
13
Q
spiral fracture
A
direction down the shaft
14
Q
greenstick fracture
A
incomplete one side is splintered, the other is just bent
15
Q
Comminuted fracture
A
more then the 2 bone peices anywhere from 3 fragaments usually displaces
16
Q
Oblique fracture
A
angled down the bone
17
Q
Pathological fracture
A
spontaneous, due to bone disease
18
Q
conditions that can cause a fracture
A
OA, RA, Osteoporosis, osteomyleitis
19
Q
Symptoms
A
immediate pain, immobility, unable to weight bare
20
Q
what if the bone is not stable during the healing process
A
likely to shorten, angulate or roate before healing and lead to poor function in long term
21
Q
SEADS stands for
A
S: swelling E: erythema A: Atrophy D: deformities S: skin change
22
Q
Assess for
A
edema, pain, muscle spasm, deformity, level of fluid loss, crepitation, warmth
23
Q
PIPS stands for
A
postion, inspect, palpate specail test
24
Q
CSM checks
A
Circulation, sensation, motion/movement
25
How to assess for circulation
colour, temp, cap refill (BILAT)
26
how to assess for sensation
Ask the casualty if there is any numbness, tingling, pins and needles, or pain at the end of the injured limb. Pain or lack of sensation could indicate a damaged nerve
27
how to assess movement
range of movement at injury site, loss can indicate damaged nerve
28
Diagnostic studies for fractures
radiology, Bone Mineral Density, Endoscopy, Mineral metabolism, serological studies, Electromyogram
29
Lab tests for fractures
ALP (liver and bone, usually elevated), Calcium, ionized calcium, phaspahet, magesium (osteoblast degeneration), ESR (specific inflammation), CRP (Non specific degeneration), RF (arthritis)
30
Closed reduction
Nonsurgical realignment of the bones to restore and keep length. The bone is immobilized until it can heal.
31
What is closed reduction followed by
Traction, cast, splint, external fixation, brace
32
Cast
plaster or fibreglass, keep the broken ends in proper position while they heal
33
Brace
Allow limited or controlled movement of nearby joints
34
Traction
used to align a bone or bones by a gentle, steady weighted pulling action
35
External fixation
metal pins or screws are placed into the broken bone above and below the fracture site. The pins or screws are connected to a metal bar outside the skin, a stabilzing frame that holds the bones in the proper position while they heal
36
Open reduction orif
Surgical, internal fixation to stabilize
-wire, screw, pins, plates, rods, nails
37
Electrical bone growth stimulation
enhance healing of fractures
38
teaching for fractures
cast care, pin care, pain control, nutrition, S/S infection. post op care, fluid/mobility/physio
39
Complication for fracture
Compartment syndrome, DVT, PE, Fat embolism syndrome, infection, decreased union
40
Fascia
layers of connective tissue with intermeshed fibres limites ability to stretch. The fibrous tissue that surounds muscle, nerves and blood vessels. Seperates the muscles. Inside is a confined space (a compartment)
41
Patho of Compartment syndrome
Swelling, vascular insufficiency, nerve/muscle compression, irreversible damage within 4-6 hours
42
Compartment syndrome assessment
unrelieved and unexplained pain in limb, distal tissue becomes pale, dusk, or edematous. Pulselessness and loss of sensation.
43
Intervention for compartment syndrome
Medical emergency!!!!
44
Cause of compartment syndrome
Crush injury, burns, tight bandages, prolonged compression of a limb during a period of unconsciousness, surgery to blood vessels of an arm or leg, Casta, extremely vigourous movement (extension under pressure)
45
6 P's
Pain, Paresthsia, poikilothermic, pallor, paralysis, pulses
46
Pain
disproportionatae pain at site/distal, aggravted by a passive movement, unrelieved by medication
47
Paresthesia
numbness and tingling
48
Poikilothermia
Decreased temp of affected extremities
49
pallor
abnormal color
50
Paralysis
late, loss of function
51
Pulses
loss of pulse, rare, an intact pulse indicates an adequate blood supplu to the extremity, but compartment syndrome may be present
52
What to do for compartment syndrome
remove any ice, lower the leg if elevated, release any constricting cast/tensor, call the physician!!!
53
What to do if someone has compartment syndrome
fasciotomy
54
Virchows Triad
Stasis, vessel wall injury, hyper coagulation
55
DVT pathogen
RBC, WBC, platelets, and fibrin adhere to venous wall forming a clot causing venous distention congestion
56
assessment for DVT
warmth, edema, redness, and or tenderness, difference bilaterally
57
Intervention for DVT
anticoagnulantion, bedrest
58
prevention of DVT
Prophylactic, anticoagulant, pneaumatic stocking
59
Fat embolism pathogen
small and multiple fat globules from the bone marrow are released into circulation. Multiple trauma
60
Assessment for fat embolism
Symptoms specific to target organ affected. Restlessness or mental staus changes, dyspnea, tachypnea, hypoxemia, tachycardia, and hypotension
61
Intervention for fat embolism
medical emergency, ABC, Supportive
62
Prevention of a fat embolism
early atbalization of fracture
63
Patho of infection (osteomyelitis)
Intro of organism into bones
64
Assessment of osteomyelitis
febrile, tachycardia, erythema, leukocytes
65
intervention for osteomyelitis
Long term IV antibiotics, internal hardware may have tp be removed, untreated may result in amputation
66
Delayed union
fracture has not healed within expected time frame
67
Malunion
healing of the bone in unacceptable position
68
Nonunion
fracture with no possible chance of healing with current treatment
69
depressed skull fracture
Bone framents forced below their normal level
70
Impacted fracture
boen driven into bone with pressure
71
Avulsion fracture
fragements of bone connected to a ligament breaks off from the rest of the bone
72
Compression fracture
common in spine from too much force of pressure
73
