The valuation of disablement of scoliosis patients gives different problems. There are no guidelines. We give recommendations for persons, which are not under treatment, which are treated part time or permanently by a brace or which underwent spine fusion. Beside the degree of the curvature degenerative alterations of the spine, the impairment of the static -- muscular performance, the impairment of the mobility of the fused spine and the pulmonary restriction are important. The pulmonary function--which is closely correlated to the chest deformity--needs special examinations. Most important is the decrease of the vital capacity therefore the use of uniform standard values is necessary.
