Operative treatment of degenerative sympotomatic lumbar scoliosis:an analysis of 37 patients / 中国矫形外科杂志

ABSTRACT

[Objective]To evaluate the surgical results and value of posterior lumbar decompression and intervertebral bone fusion with pedicle screw interval fixation in degenerative sympotomatic lumbar scoliosis.[Method]From Jan.1999 to Apr.2006,37 cases with degenerative sympotomatic lumbar scoliosis underwent posterior lumbar decompression and intervertebral bone fusion with pedicle screw interval fixation,including 21 male and 16 female patients,aged 62.6 years old averagely.All the patients were assessed by routine X-ray and Bending X-ray.CT and MRI were performed necessarily.According to patients ' symptom,total or semi-laminectomy,intervertebral bone fusion with pedicle screw interval fixation were performed.[Result]The fellow-up period varied from 1 year to 6 years(averaged,2 years and 7 months),clinical symptoms were effectively relieved after operation in all cases.Neurological functions were evaluated using JOA system,the clinical success rate in all 37 patients was 91.9%.The corrective rate was 54.8%.The average solid arthrodsis time was 11.6 weeks.The height of intervertebral disc and corrective rate had no loss.All patients X-ray of the third month and the first year didn 't show the interplantation 's clinch and breakage.[Conclusion]In the treatment of the elderly patients with degenerative sympotomatic lumbar scoliosis,first of all,the particular principle of surgical operation should be applied,the old age and long course of disease are not absolute contraindication.In addition,The technique of posterior lumbar decompression and intervertebral bone fusion with pedicle screw interval fixation can be safely performed in the elderly patients with degenerative sympotomatic lumbar scoliosis.
