osteoporosis Flashcards
what is bone made of
collagen fibers (high density collagen)
calcium
phosphate
define osteoporosis
metabolic bone disorder (most common metabolic disease)
a process of loss of bone mass
higher the corticol content the stronger the bone. true or false
true
what is the easiest way to assess OS
bone mineral density testing
how can you help prevent falls?
weight bearing exercises
improve balance
build muscle
women lose bone mass sooner than men. T or F
true
around late 30s… men around late 60s
what do biphosphates do
reverse bone loss
list some joint principles
use bigger joints over smaller avoid the same position for too long keep equal weight distribution use adaptive equipment avoid repetitive activities keep good upright posture
where is corticol bone found?
the shafts mainly
80-90% of it is calcified
bones rich in trabecular are:
more active
greater rate of turnover and resorption
what does bone remodelling involve?
repeating cycle of breaking down the existing bone
The laying down of new cells for mineralization
what is the purpose of remodelling
maintain strength of skeleton by replacing old bone with new bone
act as source of minerals (CALCIUM)
list some things calcium does for the body
regulates heartrate, blood pressure, muscle contraction
when does OS happen
when the rate of bone RESORPTION ACCELERATES while the rate of BONE FORMATION SLOWS
what does VCF stand for
vertebral compression fracture…. most common
typically seen in mid thoracic, lower thoracic and lumbar spine
