目的分析镍钛聚髌器这一骸骨骨折内固定器的设计合理性及治疗粉碎性髌骨骨折，促进骨折愈合的生物力学基础。方法利用ANSYS软件对聚滚器进行分析，建模后进行网格划分，有限元单元采用20节点、八面体的三维砖块单元，六个定义自由度，共划分了10483个单元，节点数为：17959。利
Objective To analyze the rationality of tibial fracture internal fixators and the biomechanical basis for the treatment of comminuted tibial fractures and promote fracture healing. Methods The ANSYS software was used to analyze the accumulating roller. After modeling, the mesh was divided. The finite element unit was a 20-node, octahedral three-dimensional brick element. Six degrees of freedom were defined, and a total of 10483 elements were divided. The number of nodes was : 17959. Lee
