椎弓根螺钉复位固定加椎体间植骨融合治疗腰椎滑脱症

目的 评价经后路椎弓根螺钉内固定并腰椎椎体间植骨融合术治疗腰椎滑脱的临床疗效.方法 对65例腰椎滑脱症患者行后路椎板减压,应用后路椎弓根螺钉内固定系统对腰椎滑脱椎体进行复位固定,椎体间或后外侧植骨融合.结果 随访6～24个月,临床优良率90.8%,6～12个月复查X线片均显示椎体间骨性融合.结论 本组采用椎管减压,椎体复位,椎弓根螺钉内固定并椎体间植骨融合治疗腰椎滑脱症,具有复位率、融合率高,疗效确切的特点,是治疗腰椎滑脱症比较理想的手术方式.

Treatment of lumbar spondylolisthesis with viaposterior transpedicular instrumentation and intervertebral fusion

Objective To evaluate the clinical effect of treating lumbar spondylolisthesis with viaposterior transpedicular instrumentation and intervertebral fusion. Methods The posterior decompression and surgical treatment of transpedicle screw fixation system were used in 65 patients with lumbar spondylolisthesis, to fix spondylolis lumbar vertebrae and obtain vertebra fusion and posterolateral bone grafting fusion. Results The follow-up period ranged from 6 to 24 months. The clinical excellent rate was 92%. The interspinal solid fusion was observed in all patients in X-ray between 6 to 12 month s after operation. Conclusions This unit applies vertebrallamina decompression, vertebral body reposition, posterior transpadicular instrumentation and autoiliacbone intervertebral bone grafting to treat lumbar spondylolisthesis which shows a high rate of reposition, high fusion rate, definite curative effect and reduces the complication rate after lumbar operation. It is a good way of surgery.
