Three-Dimensional Assessment of the Scoliosis

Scoliosis is a twisting deformation of the spine, including all the related anatomical structures (bones, muscles, ligaments, organs). It is essentially three-dimensional, non reducible and progressive, opposite to “scoliotic attitudes” which are simple compensatory deviation in the frontal plane to lower leg asymmetry, or to secondary deformities corrected after resolving of the cause (infection, prolapsed intervertebral disc, osteoid osteoma, etc.).
