Description: The use of femoral customized components in primary and revision hip arthroplasty represents one of the major themes for the researchers who are trying to increase the life period of the implants. There is an impediment in the development of these techniques, the high costs of the manufacturing process. For this reason the customized implants are used only in specific cases where the anatomy of the proximal femur is disturbed making the use of standard components impossible, or in revision hip arthroplasty when the bony destructions are so severe that the revision components cannot provide a long term survivorship. The comparative virtual analysis between standard and customized femoral prosthetic components shows the superiority of the last ones regarding both the surface contact between the host bone and implant and the force transfer at the bone-implant interface. Starting from the geometric model of the customized implant we generated the solid model from epoxidic resins with rapid prototyping technologies. The customized femoral components show superior behavior regarding the transfer of forces and the contact surface at the bone-implant interface being a viable alternative both in primary and revision hip arthroplasty.
