摘要
采用三维重建方法--面绘制立方体算法(MC)体绘制构建人体腰椎L3~L4腰骶段的有限元模型, 并模拟添加前韧带、后韧带、黄韧带、纤维环等主要脊椎附着软组织, 精确构建了脊柱一体化三维有限元模型, 然后进行有限元模型网格化划分并设置各部分相应的材料属性。定义不同方向的载荷和边界条件以模拟正常模型和椎间盘膨出退化模型在不同工况下所承受的应力和形变情况, 通过分析其生物力学特性, 可以为临床上椎间盘膨出和椎间盘突出等的诊治提供生物力学依据。
Abstract
The finite element model for human lumbar spinal L3-L4 is described by three-dimensional reconstruction method-marching cubes (MC). With some vital soft tissues on spine, such as anterior ligament, opisthodetic ligament, yellow ligament and fiber ring added, the complete three-dimensional finite element model of spine is rebuilt precisely. Then the finite element model is divided into mesh and the corresponding material properties of all parts are set. Finally, load and boundary conditions with different directions are defined to simulate the stress and displacement of normal model and intervertebral disc swelling degeneration model under different conditions. Which can provide biomechanical basis on the clinical diagnosis and treatment of intervertebral disc bulge and intervertebral disc protrusion by analyzing its biomechanical properties.
