Scoli Definitions (Quiz 3) Flashcards
Apical Vertebra
the most rotated vertebra within a curve; most laterally deviated
Compensation
head aligned over the pelvis in the coronal plane
Compensatory Curve
curve that develops secondary to a primary curve to maintain body alignment
Curve magnitude
degree valye of a scoliotic curve
decompensation
head malaligned over the pelvis in the coronal plane
double major curves
two structural curves
end point control
control motion of a free body
in orthotics it is the mechanical restraints an orthosis applies to the spine
Euler’s theory of elastic buckling
critical load
inferior and superior end points
last convergent vertebrae, most inferior and superior to null point
major curve
largest curve and usually has the greatest degree of vertebral rotation of all curves present
menarch
beginning of menstrual cycle
minor curve
smaller curves and usually have the least degree of vertebral rotation
more flexible and usually develop to compensate for major curves
nonstructural curve
rotary component will correct on lateral side bending
LLD
null point
horizontal line that is usually found between two vertebra
vertebrae superior to null point (within curve span) are angled in one direction while vertebrae inferior to null point (within curve span) are angled in the opposite direction
peak height velocity
growth rate of at least nine cm per year
as calculated by standing height measurements at 6 month intervals for a min of 2.5 years
