What does it mean to have rotatory thoracolumbar scoliosis?

Scoliosis is very 3D: Scoliosis is always a three dimensional deformity; the spine is not only curved when you look from the front, but it is also rotated. It is the amount of rotation that makes the curve the most visible when you bend forward and look at it. The rotation is what produces the 'so-called' rib hump.

Describes: An idiopathic scoliosis is not just a curve or lateral bend of the spine but a twisting or coiling or rotation of the spine that leads to a curvature just like coiling or twisting a rope. In this case, the "curvature" is occuring from the thoracic or chest region of the spine and extending into the lower back or lumbar spine.
