Abstract:
A three-dimensional finite element method (FEM) simulation was carried out in order to
exploit a new resurfacing prothesis design named MARMEL, proposed by a recent study with Co–Cr–
Mo material [1], for comparing a hip uncemented resurfacing with a novel carbon fiber/polyamide 12
(CF/PA12) composite to Co–Cr–Mo hip resurfacing implant.
From FE analysis, the von Mises stress range for the Composite hip resurfacing was much lower than
that in the Co–Cr–Mo hip resurfacing implant used in this comparison.
These outcomes showed that the biomimetic MARMEL hip resurfacing had the potential to reduce stress
shielding and prevent from bone fracture compared to conventional hip resurfacing implants.
