| 【Abstract】 Objective：To investigate therapeutic effects of selective decompression and fusion for lumbar cannal stenosis associated with degenerative scoliosis.Method：33 cases of lumbar stenosis with degenerative scoliosis were reviewed retrospectively.The involved segements were determined by symptoms，clinical features and radiographic documents.We carried out decompression of the nerve roots on the segments inducing the clinical symptoms and selected fusion on the segments with preoperative instability or probably iatrogenic postoperative unstable.The clinical outcomes were evaluated by Japanese Orthopedic Association（JOA） score and Oswestry Disability Index（ODI）.The SF-36 questionary was used to evaluated the patients′ life quality before and after operation as well.Result：Decompression was done on 62 segments and fusion on 52 segments in 33 patients. The average number of decompressed level was 1.9 and fusion was 1.6.The mean follow-up period was 38 months（range，12~84 months）.The average of JOA score and ODI was 15.8 and 66.5 points at the initial examination and 26.4 and 37.6 points at the final follow-up respectively（P<0.05）.All domains of SF-36 score were significantly improved postoperatively（P<0.05）.The average Cobb′s angle was preoperative 19.3 degrees and postoperative 12.7 degrees with a mean correction rate of 34.2%.Conclusion：This investigation suggests that the selected decompression and fusion for lumbar cannal stenosis with degenerative scoliosis can provide a good clinical outcome when the surgical plan is designed individually based on the careful evaluation of each patient′s features. |
