项目摘要
In the present study, in order to examine the cause of hip fracture by falls, we performed the following studies : 1) experiments to simulate falls by use of cadaveric femora, 2) finite element analyses to use finite element models created from X ray computed tomographic images of cadaveric femora, 3) construction of the system creating finite element models for individual femora. The results obtained are summarized as follows :1. Static loads were applied to cadaveric female femora (aged 89-95), and the relation between the fracture risk and the load direction was discussed. The results showed that the stress concentration is observed in the superior subcapital and posterior basicervical regions.2. From the impact tests for 10 cadaveric femora (aged 77-94), it was found that femoral neck fractures are mainly caused by compressive stresses, and that the femoral shapes and bone density influence the type of fracture.3. In the results of the finite element analyses with the model from the left cadaveric femur 65 ages male, the fracture risk on the posterior basicervical region increased with the rotation angle around the diaphyseal axis.4. It was thought that the differences of shapes among specimens had some influences on femoral neck fracture. Hence we developed a method that constructs individual finite element models of proximal femur by using the minimum amount of morphological parameters of femur.5. By this method, we can construct the models in shorter time than before, and moreover it became much easier to perform the finite element analyses taking account of individual femoral shapes.
在本研究中,为了检查由福尔斯引起的髋部骨折的原因,我们进行了以下研究:1)通过使用尸体股骨来模拟福尔斯的实验,2)使用尸体股骨的X射线计算机断层扫描图像创建的有限元模型来进行有限元分析,3)构建用于创建个体股骨的有限元模型的系统。主要研究结果如下:1.对89-95岁女性尸体股骨施加静态载荷,探讨载荷方向与骨折风险的关系。结果表明:应力集中区主要分布在上级头下区和后基颈区.通过对10例77-94岁股骨的冲击实验,发现股骨颈骨折主要是由压应力引起的,股骨的形状和骨密度影响骨折的类型. 65岁男性左侧尸体股骨模型的有限元分析结果显示,随着绕骨干轴旋转角度的增加,后基底部骨折的风险增加.认为股骨颈骨折的发生与标本的形态差异有关。因此,我们提出了一种利用最少的股骨形态参数建立股骨近端个体有限元模型的方法.通过这种方法,我们可以在更短的时间内建立模型比以前,而且它变得更容易进行有限元分析,考虑到个人的股骨形状。
