1
most common metabolic bone
disorder
Osteoporosis
2
low bone mass
and microarchitectural deterioration of bone tissue, with a
consequent increase in bone fragility and susceptibility to fracture"
Osteoporosis
3
Reduction of bone
quantity of otherwise normal bone
Osteoporosis
4
poverty of
bone with increased
radiolucency
Osteopenia
5
decreased bone
density in majority of skeleton, especially axial and proximal long bones
Generalized Osteoporosis:
6
Complex Regional Pain Syndrome and Reflex Sympathetic Dystrophy
Syndrome is also called
Sudeck’s atrophy
7
T1 -MR of hips
shows a diffuse zone of low signal intensity in the femoral
head and neck consistent with
marrow edema
Transient Osteoporosis of Hip (TOH)
8
Localized Osteoporosis
focal loss of bone density affecting
a small area of bone
9
bone mass decreases at what age
35 yo
10
Complications of osteoporosis include
Spinal compression fractures, Increasing thoracic kyphosis and other fractures
11
effective to restore AS posture
spine osteotomy
12
Subtrochanteric
femoral fractures are a complication of
Bisphosphonates
13
According to a 2009 Swedish study by
Aspberger, the incidence of mid femur stress
fracture is 50 times higher for patients on
_________ compared to untreated women
Bisphosphonates
14
Fosamax
and Actonel are
bisphosphonate drugs
15
if patient presents
with pain upon coughing, sneezing or straining, suspect
acute compression fracture
16
Progressive angular kyphotic deformity within 1 year of spinal compression fracture may result in
spinal
stenosis
17
are neurological abnormalities common with spinal compression fracture?
NO
18
Cement injected into vertebral body which usually provides
immediate/substantial
results in pain and function
Vertebroplasty
19
procedure consists of an image-guided
injection of polymethylmethacrylate
(PMMA), which is an acrylic bone cement
meant to stabilize and strengthen a
collapsing vertebral body
Percutaneous Vertebroplasty
20
uses balloon dilatation of vertebral body,
with subsequent instillation of polymethylmethacrylate.
Kyphoplasty
21
In Weightbearing Bones (vertebrae) there is preferential resorption of non-essential supporting
trabeculae and relative sparing of the major, ______
oriented stress trabeculae
vertical
22
why is Single Photon Absorptiometry unreliable?
High false negative rates
23
DEXA stands for
Dual Energy X-ray Absorptiometry
24
Dual Photon Absorptiometry is applied to the
spine and prox femur
25
DEXA scores are reported as
"T-scores" and "Z-scores."
26
comparison of a person's bone density with that of a healthy 30-year-old of the same sex.
T-score
27
comparison of a person's bone density with that of an average person of the same age and sex
Z-score
28
T-score of -1 and above
normal bone density
29
T-score of -1 to -2.5
osteopenia
30
