摘　　要：目的:建立股骨下端的三维有限元模型,以期为膝关节三维有限元的建立和研究,提供方法学和研究平台。方法:根据螺旋CT扫描图像,利用Ansys有限元软件的由下向上的点、线、面、体的建模原则,对股骨下端的三维有限元模型进行重建。结果:建立了股骨下端的三维有限元模型。结论:建立了股骨下端的三维有限元模型,该模型能逼真地反应股骨下端的真实几何结构。AIM:To build a three-dimensional finite element model of distal end of femur so as to provide a methodology and platform for the foundation and study of thre e-dimensional finite element model of knee joint motion.METHODS:According to the model-building principle from point to line to area to volume of Ansys finite element software, the three-dimensional finite elemen t model of distal end of femur was reconstructed on the basis of the images of s piral CT. RESULTS:The three-dimensional finite element model of distal end of femur was reconstructed.CONCLUSION:The three-dimensional finite element model of distal end of femur, which can reflect the real geometrical structure of the distal end of femur viv idly,has been reconstructed.
