Several authors have employed finite element analysis for stress and strain analysis in orthopaedic biomechanics. Unfortunately, the definition of three-dimensional models is time consuming (mainly because of the manual 3D meshing process) and consequently the number of analyses to be performed is limited. The authors have investigated a new patient-specific method allowing automatically 3D mesh generation for structures as complex as bone for example. This method, called the mesh-matching (M-M) algorithm, generated automatically customized 3D meshes of anatomical structures from an already existing model. The M-M algorithm has been used to generate FE models of 10 proximal human femora from an initial one which had been experimentally validated. The automatically generated meshes seemed to demonstrate satisfying results.
几位作者已将有限元分析用于骨科生物力学中的应力和应变分析。不幸的是,三维模型的定义很耗时(主要是因为手动三维网格划分过程),因此要进行的分析数量有限。作者们研究了一种新的针对特定患者的方法,该方法能够自动为诸如骨骼等复杂结构生成三维网格。这种方法称为网格匹配(M-M)算法,它能从已有的模型中自动生成解剖结构的定制三维网格。M-M算法已被用于从一个经过实验验证的初始模型生成10个近端人类股骨的有限元模型。自动生成的网格似乎显示出令人满意的结果。
