摘要

本研究的目的是比较各种常规和改性添加剂制造的用于脊柱笼的多孔材料的应力屏蔽效果。通过改变脊柱笼的设计(全多孔和混合)和材料(PEEK, CFR-PEEK，钛)进行有限元研究。所有模型均在单轴压缩条件下进行了模拟，以研究应力屏蔽效应。有限元分析结果表明，在单轴压缩条件下，混合式脊柱笼向相邻椎体传递的应力大于其他设计构型。混合钛笼对降低应力屏蔽效应效果最好。混合笼比PEEK更坚固。然而，由于CFR-PEEK笼的多孔结构，观察到应力屏蔽降低。

Comparative Analysis of Porous Titanium Spinal Cage with Conventional Spinal Cages: A Finite Element Study

The objective of this study is to compare the stress shielding effect of various conventional as well as modified additive manufactured porous materials used for spinal cages. A finite element study was performed by changing the design (fully porous and hybrid) and the materials (PEEK, CFR-PEEK, Titanium) of spinal cages. All the models were simulated under uniaxial compression, to study the stress shielding effect. The Finite Element Analysis results showed that the hybrid spinal cage transfers more stress to its adjacent vertebrae than the other design configurations under uniaxial compression. The hybrid titanium cage was most effective in reducing the stress shielding effect. The hybrid cage is stronger than PEEK & CFR-PEEK cages, however, due to the porous structure reduced stress shielding was observed.
