摘要
目的介绍一种新的脊柱内固定系统及其特点,观察腰椎管减压、横突间植骨和Diapason内固定手术治疗腰骶椎不稳定合并腰椎管狭窄症患者的早期临床疗效。方法回顾性分析总结16例腰椎管狭窄合并腰骶椎不稳定患者经腰椎管减压、横突间植骨和Diapason内固定术后临床症状、X光表现。结果16例腰椎管狭窄合并腰椎不稳定患者中,术前腰痛临床评分为47.5±0.8,术后腰痛评分(31.9±2.3)较术前明显改善(P<0.001)。随访(平均6.2个月)时,X线检查未见脊柱滑移,未发现内植物松动、断裂。无神经系统并发症和感染发生。结论应用Diapason内固定治疗腰骶椎不稳定,术后早期效果良好,手术操作容易,并发症少。
Objective To observe the preliminary clinical outcome of using a new instrumentation Diapason sys-tem and to introduce the characterization and surgical technique of this new system for treatment of un-stable lumbar spinal stenosis.Methods 16patients with unstable spinal stenosis who were treated by decompression,posterolateral intertransverse arthrodesis and transpedicle instrumentation of Diapason sys-tem,were analyzed retrospectively.Results Lower back pain(LBP)of16patients were significantly alleviated after surgery(scores of LBP before operation:47.5±0.8;scores of LBP after operation:31.9±2.3,P<0.001)?There was no implant failure,no early or later infection and no neurological complications in16patients at an average of6.2-month follow-ups.No pseudoarthrosis was observed on roe ntgenography.Conclusion Our short-term follow-up and limited cases study showed satisfactory pre-lim inary result of treating unstable lumbar spinal stenosis with Diapason internal fixation.
