[Evaluation of surgical correction of idiopathic scoliosis according to Scoliosis Research Society criteria].

Background. The aim of this study was a subjective evaluation of scoliosis surgery in cases of idiopathic scoliosis according to the criteria of the Scoliosis Research Society (SRS). Material and methods. Examinations based on the SRS protocol were performed for 135 patients surgically treated using Cotrel-Dubousset instrumentation with posterior spondylodesis. These were mainly patients with thoracic scoliosis, Cobb's angle 59.9+/-12.5 degrees . Results. Surgery led to correction of scoliosis to 34.6 degrees , i.e. 57.8% improvement, with a gradual decrease after compensation in the postoperative period. Posterior spondylodesis involved from 6 to 13 vertebrae. The summary outcome according to the SRS protocol was 3.79+/-0.44. The patients evaluated their level of activity the highest (4.09+/-0.9). Conclusions. Patients treated operatively with the CD technique achieve good overall outcome in terms of quality of life, as measured by the SRS questionnaire. The highest marks were given for activity, and the lowest for limited motion due to spondylodesis. The mean outcome is not significantly dependent either on the degree of scoliosis correction in the frontal plane or on the extent of the spondylodesis.
