有限复位内固定椎间融合术治疗稳定的退变性腰椎滑脱症临床疗效的回顾性分析

探讨有限复位内固定椎间融合术治疗稳定的退变性腰椎滑脱症的临床疗效。方法回顾分析朝阳医院骨科自2008年5月至2011年8月收治的L4～L5稳定的退行性腰椎滑脱症疾病患者17例，行后路椎管减压、椎间融合手术。所有患者均为L4椎体滑移，腰椎过伸过屈位X线测量无明显腰椎失稳表现，比较术前、术后腰疼或者下肢腿痛视觉模拟评分（VAS），患者满意度问卷调查。所有患者在术后6～12个月随访，94％患者达到脊柱骨性融合。结果随访结果中无断钉断棒现象发生，椎间融合率94％。术前术后腰痛、下肢痛VAS差异有统计学意义（P〈O．01）。结论有限复位内固定椎间融合术治疗稳定的退变性腰椎滑脱症的短期临床随访效果满意。

Partly reduction and intervertebral fusion for stable degenerative lumbar spondylolisthesis: a retrospective analysis

Objective To analyze retrospectively clinical curative effect of partly reduction and intervertebral fusion on stable degenerative lumbar spondylolisthesis. Methods A retrospective follow-up analysis included 17 patients with L4-L5 stable lumbar degenerative spondylolisthesis receiving partly reduction and intervertebral fusion treatment from May 2008 to August 2011. Visual analog score（VAS） of back pain and leg pain before and after operation were compared. The lumbar 4 was found slipped in all patients and lumbar hyperextension and hyperflexion X-ray files showed no evidence of lumbar instability. All patients were followed up in 6-12months after operation. Results There was no nail or rod broken, and intervertebral fusion rate was 94%. VAS of low back pain and leg pain were significantly decreased post-operatively（P 〈 0.01）. Conclusion Short-term clinical outcome of partly reduction and intervertebral fusion for treatment of stable degenerative lumbar spondylolisthesis is satisfactory.
