As one more in a long line of metal-on-metal hip implants to be plagued with recipient problems, the Biomet M2A Magnum first became available in October of 2004. The design of the Biomet M2A was meant to maximize mobility, minimize friction and offer a variety of size ranges to allow surgeons to more precisely fit the implant to the specific anatomy of each patient. Unfortunately, Biomet’s design has been found to have many of the same risks as other metal-on-metal hip implants such as metallosis, nerve and tissue damage in the area surrounding the implant, bone loss and loosening of the device which contributes to hip dislocation.
