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

30

when is a vertebral compression fracture suspected

>6cm loss in height
