what is the most common osteoporosis-related fragility fx

A

vertebral compression fx

22
Q

when is bone mass at its peak

23
Q

what gender loses bone mass sooner and why

A

women, due to perimenonpause

24
Q

when and why are men likely to experience bone loss?

A

60s, hypogonadism

25
what are risk factors for fx
low physical function advanced age dec bone mineral density alcohol or substance abuse
26
stages of fx healing
hematoma formation cellular proliferation callous formation ossification consolidation and remodeling
27
when is granulation and acute inflammatory rxn and granulation tissue is formed ?
day 1-2
28
when does callus formation occur ?
week 1-3
29
remodeling of the medullary canal occurs during what time frame
medullary canal and organized lamellar bone
30
when does the external callus form?
week 6
31
factors that can hinder proper fracture healing
inadequate blood supply poor general nutritional status corticosteroid therapy presence of foreign bodies/infection or necrotic tissue
32
clinical manifestation of fx
pain and tenderness edema and ecchymosis loss of mobility and function of the involved body part inc dependence on family and friends dec in the individual's ability to perform ADLs depression and anxiety
33
are VCFS typically painful or painless?
painless
34
when VCFS are painful what can reproduce it ?
pressure over the vertebrae or certain positions
34
what are VCFS associated with
height loss and respiratory function
35
what are some fx complications
deformity malunion delayed union nonunion ( fibrosis union or a false union AKA pseudoarthrosis)
36
which bone type is at risk for a fat embolism and why ?
long bones and bony pelvis bc it contains the most bone marrow
37
typically where does a fat embolism travel to
the lung and can block the pulmonary vessels and dec diffusion of the alveoli
37
T or F a fat embolism is never fatal
false, it could be potentially fatal
38
fx are often diagnosed by what ?
visual inspection and confirmed by rdiographs
39
what is the goal for treatment of fx
to promote hemodynamics stability comfort early mobility to limit complications
40
vertebroplasty
direct injection of polymethyl methacrylate bone cement into the fractured vertebrae
41
kyphoplasty
insertion of a balloon to expand vertebra followed by bone cement to stabilize the vertebral body
42
why does fractured bone need to be immobilized ?
bc if its not it could delay the healing
43
if you keep older patients immobilized what are some complications that can occur
pulmonary complications, pressure ulcers, deep vein thrombosis, UTI
44
autogenous bone grafting is often taken from what
illiac crest or fibula
45
bone grafting is used for what ?
to enhance bone repair and formation
46
fx heal in children heal in how long ?
4-6 wks
46
fx healing in adolescents how long ?
6-8 wks
47
fx healing in adults take how long ?
10-18 wks
48
less than ________ of older adults with hip fx will regain their prior level of function
50%
49
what are some negative predictors for healing
renal or vascular insufficiency smoking alcoholism diabetes mellitus
