According to the Scoliosis Research Society “Scoliosis is a sideways curve of the spine that measures greater than 10 degrees on x-ray. Instead of a straight line down the middle of the back, a spine with scoliosis curves sometimes looks like a letter “C” or “S.” Some of the bones in a spine with scoliosis may rotate, making the person’s waist or shoulders appear uneven.
HOW IS SCOLIOSIS DIAGNOSED?
A forward bend test, (Adams test),
will show a rib hump on the side where the ribs are rotated backwards.

A Scoliosis diagnosis is confirmed with a standing x-ray of the entire spine. The angle of the curve is called the Cobb angle. A straight spine has a curve of 0º; however, a spinal curve greater than 10º is diagnosed as scoliosis.
Between 0º and 10º is considered “postural asymmetry” which is not true scoliosis.
An X-ray from the side is used to determine thoracic kyphosis (or round back appearance) and the amount of lumbar lordosis (swayback).
