How can scoliosis affect the vertabrae?

Like a coiled spring: Grab both ends of a spring and twist. This creates a helical curvature of the spring. Similar in the spine. The spine is twisted along its length with the apical vertebra (middle of curves) twisted toward the convexity, protruding the ribs backwards on this side. This rotation then disappears at the neutral vertebra (not rotated) which transition between curves.

Rotation: Normally, when you look at the back from behind it is straight; when there is a curvature greater than 10 degrees it is known as scoliosis. The first change that occurs, however, is a rotation of the vertebrae. This is cilinicly seen as an assymetric trunk rotation, in layman's terms this is known as a "rib hump".
