Abstract:
This study is aimed at designing, optimizing, and validating a posterior lumbar interbody cage (PLIF) model based on the 3D printing method, which provides patients with a suitable customized design capable of providing proper mechanical support. In the content of this study, the CATIA software is used for modeling of three symmetrical cage models with different porosities. Then, two replicates of each cage model are assembled in the disc space of a parametric geometry of the L1–L2 vertebrae. The proposed models are meshed, and a finite element analysis is conducted through compressive and moment loadings. The overall stiffness and von Mises stress and strain of each model are determined.
Keywords:
PLIF cage, additive manufacturing, design and optimization, finite element analysis, von Mises stress, porous structure, mechanical properties.
