考虑骨盆的髋关节假体置换对髋关节应变分布的影响

The Effect of Hip Replacement on Strain and Stress Distribution of Hip Joint Considering Pelvis

摘要: 本研究在考虑骨盆的情况下，对假体置换前后的髋关节进行有限元仿真。考虑到置换前后髋关节受力的真实情况，采用无骨盆和有骨盆两种有限元模型进行模拟。通过研究得出置换前后有无骨盆的应变分布规律，进而进行比较，得出骨盆对髋关节应变分布规律的影响，从而为髋关节物力学分析提供一定的理论依据。模型的参数和边界条件仍需要优化。

Abstract: The laws of strain and stress distribution were analyzed by finite element method after the re-placement of artificial hip joint prostheses with pelvis and without pelvis in this research. We found the effect of pelvis on strain and stress distribution of hip joint after the replacement of artificial hip joint prostheses, thereby providing guidance to medical companies and clinicians when manufacturing and operating. The parameters of the model and the boundary conditions still need to be optimized.
