三维有限元分析在脊柱生物力学中应用研究

Utilization of three-dimensional finite element method in spinal biomechanics

三维有限元分析方法作为脊柱生物力学研究方法之一,随着人们对脊柱力学特性的认识,有限元分析软件在国内外不断开发与应用,不但促进了有限元技术的发展,而且推动着脊柱生物力学研究更深入发展。作者从有限元法概念及原理、脊柱有限元模型构建、颈椎和腰椎三维有限元应用、内固定器械三维有限元分析等方面综述了近年来的一些研究进展。

As one of the research methods used in spine biomechanics, the analysis software of three-dimensional finite element has got unceasing development with the deeply further understanding for spinal mechanics characteristic both in China and the world. It has not only promoted the development of finite element technic itself, but also impulse further research on spinal biomechanics. This paper has reviewed some recently advances, focusing on the concept and principle of finite element method, construction of spinal finite element model, application of finite element method in cervical spine, lumbar spine and internal fixation device and so on.
