三种不同术式治疗退变性腰椎滑脱的疗效观察

目的:探索单侧PLIF治疗退变性腰椎滑脱症。方法:2004～2006年采用单侧PLIF治疗退变性腰椎滑脱24例,并在手术时间、神经损伤、融合率、平均矫正丢失度、椎间隙高度维持率及临床疗效方面和PLF及PCF组进行比较。结果:在手术时间上单侧PLIF组和PLF组无差异,但和PCF组有差异。在神经损伤、断钉方面三组无差异。在融合率、维持间隙高度及平均矫正丢失度方面,单侧PLIF组和PCF组无差异,但和PLF组有差异,优于PLF。结论:单侧PLIF术式为治疗退变性腰椎滑脱的理想方式。

Effectiveness of three different procedures in lumbar degenerative spondylolisthesis

Objective： To observe the therapeutic effect of unilateral posterior lumbar interbody fusion（PLIF） in treatment of lumbar degenerative spondylolisthesis. Methods：In 2004 and 2006,24 patients with lumbar degenerative spondylolisthesis received surgical treatment with posterolateral fusion （PLF） or posterolateral circumferential fusion （ PCF ）. The clinical data were compared between the two groups with regard to duration of operation, condition of nerve injury and fusion, vertebrae loss and vertebral height after correction. Results ： There was no difference between PLIF and PLF in time consumption in operation, but PCF was different. The incidence of nerve injury and broken nails remained the same in the three groups. When the condition of fusion, height of lumbar interbody and vertebrae loss after correction were compared, no difference was observed between unilateral PLIF and PCF, but PLF was different. Conclusion： The unilateral PLIF is a sound procedure in treatment of lumbar degenerative spondylolisthesis.
