摘要
目的探讨后路腰椎管减压、Basis椎弓根螺钉系统复位固定加环形植骨融合治疗腰椎滑脱症的疗效。方法对32例腰椎滑脱症患者行后路腰椎管减压Basis椎弓根螺钉复位固定加环形植骨融合术。结果 32例均获随访,时间4～25个月。患者术后症状均消失,X线片示29例滑脱完全复位,3例部分复位。所有患者均达骨性融合,无椎弓根钉松动、断裂及再滑脱现象。根据侯树勋等疗效评定标准评定:优23例,良7例,可2例,优良率94%。结论 Basis椎弓根固定系统复位固定加环形植骨融合治疗腰椎滑脱症临床疗效满意,可作为治疗严重腰椎滑脱的首选方法。
Objective To summarize curative effects of the decompressive laminectomy by posterior approach,reduction of spondylolisthesis fixed with Basis pedicle screw and posterior instrumented circumferential fusion in the treatment of lumbar spondylolisthesis.Methods Thirty-two patients with lumbar spondylolisthesis treated with posterior instrumented circumferential fusion were studied retrospectively.Results All the patients received follow-up for 4~25 months.Symptoms were disappeared after operations in all the patients.The postoperative X-ray films showed that 29 patients obtained complete reduction,3 partly reduction.This surgical methods produced satisfactory outcomes with the 100% osseous fusion.All the bone grafts were fusion,without screws loosening or breakage or internal fixation loosing was found.Based on Hou Shu-xun Criteria for therapeutical evalution,the efficacy was as follows:excellent in 23 cases,good in 7,and fair in 2,the rate of excellent and good was 94%.Conclusions Posterior instrumented circumferential fusion with Basis pedicle screw is an effective method for treating severe lumbar spondylolisthesis.
