摘要
目的 本研究旨在确定多节段脊髓型颈椎病(CSM)患者进行颈椎后路单开门椎板成形术(PCOL)时的最佳开门角度(OA).研究方法 利用颈椎三维模型模拟PCOL,计算不同OA下的椎管扩大容积和比例,以及扩容比增幅;同时在传统二维平面测量PCOL后椎管矢状径.结果 随着OA的增加,椎管扩大容积和扩容比显著增加,其中OA为30°时通过三维测量得出的扩容效果最佳,而OA为60°时通过二维测量得出的扩容效果最佳.此外,OA为30°和60°时扩容比增幅和扩径比增幅最大,且差异有统计学意义(P＜0.05).结论 开门角度与颈椎管扩大容积存在密切关系,通过三维测量方法计算出OA为30°时扩容效果最佳,而通过二维测量方法计算出OA为60°时扩容效果最佳.
Abstract
Objective To determine the optimal opening Angle(OA)for posterior cervical open-door lami-noplasty(PCOL)in patients with multilevel cervical spondylotic myelopathy(CSM).Methods The three-dimen-sional model of cervical spine was used to simulate PCOL,and the volume and proportion of vertebral canal expan-sion under different OA were calculated,as well as the expansion ratio increase.At the same time,the sagittal diam-eter of spinal canal after PCOL was measured in traditional two-dimensional plane.Results With the increase of OA,the enlarged volume and the dilatation ratio of the spinal canal increase significantly.When OA was 30°,the dilatation effect obtained by three-dimensional measurement was the best,while when OA was 60°,the dilatation ef-fect obtained by two-dimensional measurement was the best.In addition,when OA was 30° and 60°,the expansion ratio and expansion ratio increased the most,and had statistical significance(P＜0.05).Conclusion There is a close relationship between the OA and the expansion volume of the cervical canal.The expansion effect is best when the OA is 30°calculated by three-dimensional measurement method,while the expansion effect is best when the OA is 60° calculated by two-dimensional measurement method.
