摘要:
目的:通过将正常人体脊柱胸腰段(T11~L2)的CT图像纳入Mimics和Ansys软件,构建正常人体脊柱胸腰段及单纯胸腰段椎体压缩性骨折的三维有限元模型,并探讨其意义。方法:将正常人体的脊柱胸腰段CT图像以Dicom标准直接输入Mimics12.01软件,并建立胸腰段椎体、韧带、椎间盘的三维几何面网络模型,并确立单元类型及材料属性。然后将实体模型导入Ansys12.0有限元软件中,生成正常人体脊柱胸腰段三维有限元模型,在此基础上再生成单纯胸腰段椎体压缩性骨折的三维有限元模型。结果:获取完整、精确、逼真的胸腰段有限元模型。结论:建立两个三维有限元模型,并通过后期的有限元力学分析,对单纯胸腰段椎体骨折的诊疗具有重大意义,尤其对运用复位床托治疗单纯胸腰段椎体压缩性骨折的新型疗法及其作用机制的研究,对推广和提升其疗效有具有指导意义。
Abstract:
Objective: To establish and analyze the significance of the finite element compression fractures model of thoracolumbar spine through the Mimics and Ansys software. Methods: The CT images of normal human thoracolumbar spine with Dicom standard were directly imported into Mimics12.01 software, to establishment of 3D geometric surface network model of thoracolumbar vertebral body, ligament, intervertebral disc, and to establish the element types and material properties. Then the solid model was imported into Ansys12.0 finite element software, generating a three-dimensional finite element model of normal human thoracolumbar spine, further more, which generating a three-dimensional finite element compression fractures model of thoracolumbar spine. Results: The finite element model of thoracolumbar spine was obtained completely and accurately. Conclusion: The two 3D finite element models are established and analyzed. It is of great significance to promote and improve its efficacy, to diagnose and treat of pure thoracolumbar vertebral fracture, and to detect mechanism of the use of reduction bed for simple thoracolumbar vertebral compression fracture.
