摘　　要：目的探讨多节段腰椎有限元模型的建立方法,为脊柱生物力学的研究提供条件。方法选取一正常男性自愿者L3～L5节段为研究对象,通过CT断层扫描、图像数字化分析及ADINA软件处理建立多节段腰椎有限元模型,并模拟力学作用进行模型真实性验证。结果建立了正常中国男性L3～L5运动节段三维有限元模型,模型总结点数为16 532个,包括12 130个Solid单元,208个Truss单元,16个planar单元。结论利用CT图像和ADINA软件建立新型腰椎运动节段三维有限元模型,为腰椎运动节段有限元模型的建立提供了一种简便、准确的方法,为探究腰椎多个运动节段三维有限元模型在各种应力应变状态下的生物力学特性创造了条件。Objective Establishing a finite element model of multi-stage lumbar vertebra will provide platform for further biological mechanics research.Methods L3~L5 stages of a normal male volunteer were selected as study objects;through the CT scanning,digitized image analysis and ADINA software processing,a finite element model of the lumbar spinal motion segment was established and was verified by simulating the mechanical action.Results A normal Chinese male L3~L5 lumbar spinal motion segment finite element model was established with a total of 16532 summary points,including 12130 solid units,208 truss units,and 16 planar units.Conclusion It has provided one easy and accurate method for the establishment of normal lumbar spinal motion segments.By analyzing and studying the model,it is possible to study the biological mechanics performance under each condition.
