| 摘 要： | 背景:通常的力学实验手法基本上无法直接应用于人体且模型间可比性低,对人体的力学行为进行有限元数值模拟就成为深化对人体认识的一种有效手段.目的:建立骨质疏松股骨三维有限元模型.方法:根据国人股骨平均参数,选择重度骨质疏松老年男性患者1例,年龄86岁,排除髋关节疾患.通过螺旋CT扫描获得骨质疏松股骨图像数据,将图像数据导入图像处理软件Mimics 11.1进行图像处理,生成股骨骨皮质内、外表面的轮廓曲线;再将轮廓曲线数据导入建模软件Unigraphic NX4.0进行实体建模,得到具有骨皮质、骨松质、骨髓腔的股骨三维模型;将三维模型数据导入有限元分析软件Ansys11.0进行赋值、网格划分、定义接触等操作建立骨质疏松股骨三维有限元模型.结果与结论:建立了骨质疏松股骨三维有限元模型,为骨质疏松股骨限元模型的建立提供了切实可靠的方法,为研究骨质疏松股骨骨折的固定方法、关节置换等创造了条件.

| Abstract: | BACKGROUND:Usual mechanics experiment approach cannot be applied directly to human body and the inter-comparability of models is low.Therefore finite element numerical simulation to mechanical behavior of human body has become an effective method for better understanding of the human body.OBJECTIVE:To establish a three-dimensional finite element model of femoral osteoporosis.METHODS:According to the average Chinese femur parameters,1 male patient with severe osteoporosis,aged 86 years,with no hip joint dise... |
