Scoliosis is defined as a three-dimensional deviation in the axis of a person's spine[REF] In the diagnostic sense it is defined as a spinal curvature of more than 10 degrees to the right or left as the examiner faces the person, i.e. in the coronal plane.
Scoliosis has been described as a biomechanical deformity, the progression of which depends on asymmetric forces otherwise known as the Heuter-Volkmann law [REF].
