class 10: MSK back Flashcards
what is t score
bone density tests, representing how much a person’s bone density deviates from the average
how do we interpret t-score
–1 or higher, your bone is healthy.
–1 to –2.5, you have osteopenia, a less severe form of low bone mineral density than osteoporosis.
–2.5 or lower, you might have osteoporosis.
what back movement do we avoid if patient has osteoporosis
rot and flexion
what comprises the neural arch
pedicles and lamina
Spondylosis
Degeneration of intervertebral disc
Spondylolysis
Defect in pars interarticularis or the arch of the vertebra
Spondylolisthesis
Forward displacement of one vertebra over
another
Retrolisthesis
Backward displacement of one vertebra on
another
Spondylosis - pop
> 50 years old
spondy young
Spondylolysis - 15-20 years old
Spondylolisthesis - 20 years old. It can
progress to degenerative
spondylolisthesis with age
Spondylosis - location
Back
(unilateral)
all the spondy are relieved with what movement
sitting
all the spondy are aggravated with what movement
ext
relief with disc herniation and spinal stenosis
spinal stenosis - flexion
disc herniation - ext
scolio - cause
Genetic, idiopathic, caused by
some congenital problem
scolio - vert body
Vertebral bodies rotate to the
convexity of the curve
scolio - ribs on the convex side
̶Ribs pushed posteriorly on
convex side “rib hump”
scolio - SP
̶Spinous process deviates
toward the concave side
scolio - cave pelvis
high
scolio - cave tight or loose muscle
tight
scolio - cave rib anterior or posterior
anterior
scolio - cave vert height
A decrease in vertebral height
scolio - cave intercostal space
decreased
scolio - cave lung volume
decreases
