【摘要】 目的探讨后路应用椎弓根钉复位固定、减压、椎体间或后外侧植骨融合治疗腰椎滑脱症的临床疗效。方法对38例腰椎滑脱症(~度)行后路椎板减压,应用HOIST、GSS、USS三种不同内固定方法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87%,6~12个月复查X线片均显示椎体间骨性融合。结论上述三种椎弓根螺钉系统能有效撑开提拉滑脱椎体,复位满意,固定力强,采用椎体间或后外侧植骨融合能有效提高植骨融合率,增加脊柱的稳定性。更多还原

【Abstract】 Objective To analyze the effect of treatment of lumbar spondylolisthesis with HOIST、GSS、USS pedicle reduction,fixation,decompression,interspinal bone grafting fusion or posterolateral bone grafting fusion.Methods The posterior decompression and the system of HOIST,GSS,USS pedicle screw were used in 38 patients with lumbar spondylolisthesis to fix spondylolis lumbar vertebrae and obtain vertebra fusion and posterolateral bone grafting fusion.Results The followed up period ranged from 6 to 24 months.The clinical excellent rate was 87%.The interspinal solid fusion was observed in all patients in X-ray between 6 to 12 months after operation.Conclusion The three pedicle screw system can distract the slipped vertebrae effectively to provide the sufficient space for the complete decompression with the satisfactory reduction and the strong fixation strength.The interspinal bone grafting fusion or the posterolateral bone grafting fusion can increase the fusion rate effectively and enhance the stability of spine.更多还原
