Flashcards in osteoporosis Deck (46)
Loading flashcards...
1
trabecular bone
interior
weaker, softer
more affected by OP
2
cortical bone
outer
riged, stronger
less affected by OP
3
resorption stage
osteoclasts (cutters)
4
formation stage
osteoblasts (builders)
5
peak bone mass age
30
6
__ associated with rapid decline in bone mass
menopause
7
bone strength reflects two main features
bone density and quality
8
what does T score evaluate
bone density
9
normal t score
osteopenia t score
osteoporosis t score
-1, 0
-1--2.5
-2.5
10
LBD / D for
men and pre menapausal women
11
T/F half of post menopausal # occur in women whose BMD doesn't have OP
T
12
T/f there is a standard for measuring bone quality
no
13
primary type 1 osteoporosis
women after menapause
14
primary type 2 osteoporosis
ppl over 70
m=w
15
secondary osteoporosis
result of a medical condition
can arise at any age
m=w
16
fragility fracture
fracture from height or less
17
common fracture site osteoporosis
spine wrist hip humerus
18
diagnose osteoporosis
Risk factor assessment
bone density
rule in / out secondary OP
DXA (bone density)
19
risk factors OP
increased thyroid hormone
age, family, small, female, life, depression
20
fracture risk assessment tools
CAROC
FRAX
21
difference CAROC and FRAX
CAROC: age, sex, hip BMD
FRAX: same as above plus height weight family lifestyle and RA
22
t/f DXA tells you about bone quality
no - just density
23
what do you do if someone is
low
mod
high
risk for fracture
nothing - high impact
other risk factors - non contact sports
meds - walks / minimize falls risk activities
24
pharmaceuticals for OP
antiresorptive
anabolic / bone formation
25
antiresorptive agents
slow down osteoclasts
26
anabolic / bone formation
accelerate osteoclasts
27
hormone replacement therapy side effects
long term use can inc risk of
breast cancer, stroke,
CV disease
and thromboembolism
28
three joint surgeries for OP
joint fixation
replacement
vertebral surgery
29
objective assessed OP
historical height loss
prospective height loss
posture
breathing
strength, flexibility, special tests
aerobic capacity
balance
