棘突椎板截骨回植在腰椎手术中的应用

目的：探讨腰椎后路手术中棘突椎板截骨回植的方法及疗效。方法：回顾性分析我院骨科自2000年11月至2004年7月收治的腰椎间盘突出症及腰椎管狭窄症患者中123例接受了腰椎棘突椎板截骨回植术患者的临床资料及治疗效果。结果：107例获得2个月～3年8个月随访（平均16．5个月），复查CT示回植骨块完全愈合，椎管得到扩大，骨愈合率达100％。无腰椎不稳及继发性腰椎管狭窄等并发症发生。结论：腰椎后路手术中，将截下的棘突椎板以不同方式回植，重建腰椎后部结构的完整性及稳定性，可以防止术后腰椎不稳及医源性腰椎管狭窄等并发症的发生。

Application of lumbar spinous process and lamina osteotomy replantation

Objective:To study the method and effect of lumbar spinous process and lamina osteotomy and replantation in the posterior approach operation of the lumbar vertebrae.Method:To analyze retrospectively the clinical data of 123 patients from December,2000 to June,2004.They underwent the lumbar spinous process and lamina osteotomy and replantation.Result:107 patients were followed up.The follow-up time was from 2 months to 36 months(average 16.5 months).CT re-examination showed the replanted spinous process and lamina had healed completely,and the lumbar canal was widened.No complication occurred such as instability of lumbar vertebrae,low back pain and so on.Conclusion:By replanting the resected lumbar spinous process and lamina,the complexity and stability of the lumbar posterior structure can be reconstructed,in this way we can prevent the occurrence of instability of the lumbar vertebrae and lumbar stenosis caused by operation.
