scoliosis Flashcards
(27 cards)
types of scoliosis
structural scoliosis
non-structural scoliosis
structural scoliosis
IRREVERSIBLE lateral curvature with fixed rotaion of the vertebra
vertebral bodies rotate into the convexity while the spinous processes rotate toward the concavity
example of structural scoliosis –> right curve w/ left rotation
if the thoracic spine is involved
–> forward bending produces a posterior rib hump in the thoracic spine on the convex side of the curve
what is structural scoliosis not corrected by
positioning or voluntary effort
non-structural scoliosis is also called
functional scoliosis
non-structural scoliosis
REVERSIBLE lateral curve that tends to be positional and dynamic in nature
no structural or rotational changes in the alignment of the vertebra
correction of non-structural scoliosis
forward bending
positional changes
muscles contractions
description of curves
direction
major curve
compensatory curves
curve name
direction of the curve
identified by side of convexity
major curve
most significant curve in the deformity
compensatory curve
those that develop in response to major curves
–> position on the shoulder level and over the pelvis
–> eyes on the horizon and horizontal as well
curve name
where the level of the apex of the curve occurs
sites of curves
could develop in the lumbar spine or the thoracic spine or both at the same
usually wont have in the cervical spine –> compensatory curve more likely to occur here
shapes of curve
long c-curve
s-curve
long c-curve
extends the length of the thoracic and lumbar spine
s-curve
most common type of curve seen in idiopathic (unknown) scoliosis
involves a major and a compensatory curve
complications of structural scoliosis
cosmesis
pts will look twisted –> have a rib hump
mostly involves the thoracic spine b/c it twists the ribcage
pulmonary complications
cosmesis
especially of the thoracic spine is involved d/t deformation of the ribs
pulmonary complications
rotation causes the ribs on the convex side of the curve to push posteriorly
–> causing a rib hump and narrowing thoracic spine
on the concave side
scoliosis causing restrictive pulmonary dz
on the concave side (pulm complications)
ribs move anteriorly causing a widening and a hollow in the thoracic spine
approximation of ribs
axis of motion for the ribs to change
scoliosis causing restrictive pulmonary dz
can sometimes case cardiac problems if the curve is large enough
severity of curves
mild
moderate
severe
mild
less than 20 degrees
moderate
20-40 or 50 degrees
