Traditionally, hip replacement implants are a combination of a metal ball that slides in a polyethylene (plastic) cup replacing the person’s worn bony ball and socket. Because the plastic liner can wear down over time the younger more active patient can wear out a joint relatively quickly leading to the need for a replacement of the original replacement. The orthopedic implant company, Biomet, has recognized this shortcoming in implant design and has developed a replacement to address the higher demands of more active, higher demand lifestyles. The Biomet magnum hip (M2a –Magnum™) is a metal-on-metal hip prosthesis in which a large metal ball bearing revolves against a metal cup thereby eliminating the plastic liner.
Biomet Magnum Hip at the Zehr Center
These metal on metal designs such as the Magnum hip replacement are more stable and there is great promise that this design type will last longer and tolerate more stress for the younger, active individual. There are some concerns with large metallic hip designs and they are not for everybody as indicated by some recent scientific studies.
