Bone remodeling and strain distribution in the femur was studied after implantation of LTI pyrolytic carbon, bioglass coated Co-Cr-Mo alloy, and carbon coated porous Co-Cr-Mo alloy intramedullary plugs. Mechanical testing and finite element analysis has shown that the intramedullary stems significantly alter the strain pattern in the femur. However, no statistically significant differences were observed among the implant groups. The analytical and experimental results were found to be in good agreement. Radiographically, differences were observed in the bone remodeling around the carbon implant compared to either of the Co-Cr-Mo based implants. Both internal and external bone remodeling takes place when an intramedullary implant is present.
在植入LTI热解碳、生物玻璃涂层钴铬钼合金和碳涂层多孔钴铬钼合金髓内塞后，对股骨的骨重塑和应变分布进行了研究。力学测试和有限元分析表明，髓内柄显著改变了股骨的应变模式。然而，在植入物组之间未观察到统计学上的显著差异。分析结果与实验结果吻合良好。影像学检查发现，与任何一种钴铬钼基植入物相比，碳植入物周围的骨重塑存在差异。当存在髓内植入物时，内部和外部骨重塑都会发生。
