有限元分析在股骨远端骨折内固定中的应用研究进展

Research progress on application of finite element analysis in internal fixation of distal femoral fractures

股骨远端骨折多为粉碎性、不稳定骨折,常累及关节面,而内固定是治疗股骨远端骨折的首选方案。采用有限元分析法可对股骨远端进行重建模拟研究,探讨骨折损伤机制,分析不同内固定的生物力学特性,指导内固定方式及材料的改进。本研究从有限元角度出发,对股骨远端有限元建模及临床应用价值进行综述。

Most distal femoral fractures are comminuted and unstable,often involving the articular surface,and internal fixation is the preferred treatment for distal femoral fractures.Finite element analysis method can be used to study the reconstruction and simulation of the distal femur,explore the injury mechanism of fracture,analyze the biomechanical characteristics of different internal fixations,and guide the improvement of internal fixation methods and materials.This study reviewed the finite element modeling of distal femur and clinical application value from the perspective of finite element analysis.
