Abstract：Objective To investigate the surgical method of selective posterior decompression, pedicle screw ifxation and interbody fusion in the treatment of degenerative scoliosis ( DS ) and the clinical results.Methods 32 patients with DS underwent posterior surgical treatment in our Department from August 2005 to June 2012, whose data were retrospectively analyzed. The Oswestry Disability Index ( ODI ) scores, Japanese Orthopedic Association ( JOA ) scores of low back pain and the improvement rate of JOA scores were used to evaluate the preoperative and postoperative results.Results 32 patients underwent posterior surgical treatment, which was successfully completed with no death. All patients were followed up for an average period of 3.4 years postoperatively. According to the imaging examination, no loosening, breakage or secondary scoliosis was found. The ODI scores were ( 61.35±15.68 ) points, ( 26.21±16.32 ) points and ( 22.32±9.58 ) points respectively before the operation and at 6 and 24 months after the operation, and the differences were statistically signiifcant (P<0.05 ). The JOA scores of low back pain were ( 12.26±2.34 ) points, ( 15.28±2.32 ) points, ( 23.86±2.67 ) points before the operation and at 6 and 24 months after the operation, and the differences were statistically signiifcant (P<0.05 ). The improvement rate of JOA scores was 88.3%. Conclusions The surgical method of selective posterior decompression, interbody fusion, pedicle screw ifxation and reconstruction of the spinal balance after appropriate correction is effective in the treatment of DS, which can improve the life quality of patients with DS.
