Abstract:
Objective To investigate the surgical strategy for degenerative lumbar scoliosis (DIS)and evaluate the clinical results of the posterior correction and fusion technique. Methods From May 2003 to May 2009,27 patients with DIS were treated posterior operation. All the patients were performed posterior laminectomy,spinal fusion and correction with pedicle screws system. Among the patients, 18 cases with posterolateral bone grafting,9 cases complicated spondylolishesis with PLIF intervertebral combined with posterolateral fusion. Results All the cases were followed up for a minimum of 12 months and 88.9% (24/27) of them had excellent or good outcome, Oswestry score was(21.54 ± 1.95 )%;22 cases were followed up for 24 months and showed a rate for excellent or good results of 86.4%( 19/22),and Oswestry score was (24.26 ± 2.32)%. Oswestry scores of the postoperative 12,24 months were lower than that before operation (57.83 ± 2.71 )%. There was statistical difference in the cases preoperation and postoperation. Correction of scoliosis of the coronal plane was 47.2%. Preoperative lumbar lordosis was augmented from 23.6°± 8.3° to 43.8°± 9.1°. One case complicated with wound infection during perioperation period, and 2 eases with heart diseases. The screw of 1 case was loosening at 3 months postoperation. Conclusion Decompressing thoroughly and improving lumbar lordosis, the operation of posterior correction and bone graft fusion shows good results for degenerative lumbar scoliosis.
