【摘要】 目的 探讨通用型脊柱内固定系统(GSS)在腰椎管狭窄症伴退变性滑脱患者手术中的应用价值。

    方法 对16例腰椎管狭窄症伴退变性滑脱患者行后路全椎板减压、GSS内固定加植骨融合术，其中多节段腰椎管狭窄11例，单节段腰椎管狭窄5例；L4滑脱9例，L5滑脱7例；Meyerding分类Ⅰ度滑脱14例，Ⅱ度滑脱2例。

    结果 术后随访6~24个月，平均14个月，采用Stauffer-Coventry下腰椎术后疗效评定标准，优良率为88%，植骨融合率为100%，GSS无松动退出及断裂现象。

    结论 在腰椎管狭窄症伴退变性滑脱后路全椎板减压术中，GSS系统可提供滑脱复位，恢复椎间隙高度及腰椎生理前凸，术后即刻稳定，植骨融合率高，是一种安全有效、操作简便的内固定系统。

    【Abstract】 Objective To explore the value of general spine system (GSS) fixation which was applied in operation of the lumbar spinal stenosis accompanyed by degenerative spondylolisthesis.Methods 16 cases suffered from the diease undergone the posterior laminectomy(decompression),fixation with GSS and fusion with bone grafting,among them 11 cases were multiple segments,another 5 cases were single.9 cases of spondylolisthesis occured in L4,7 cases in L5.14 cases were Ⅰ° by classification of Meyerding,2 cases were Ⅱ°.Results Period of follow up was 6 to 24 months(average 14 months).The excellent and good rate was 88% by standard of Stauffer-Coventry.Rate of fusion was 100%.There were no loosening,retreat and fracture of GSS.Conclusion GSS is a safe and effective fixation system which can reduce spondylolisthesis,produce stablity temporary post-operation and preserve the physical height and curve of lumbar spine.It is an easy performing procedure and high rate of fusion. ......
