M2a-Magnum™ Metal-on-Metal Hip Replacement

Although the polyethylene (plastic) liner used in traditional hip replacements is extremely durable, the amount of stress that very active people can place on the liner, may lead to premature wear. The M2a-Magnum™ Metal-on-Metal Hip Implant replaces the traditional polyethylene liner with a single piece metal cup designed to provide long-term resistance to wear. This enables you to continue participating in regular low-impact activities with less worry about premature wear on your hip components. Extensive testing has shown that the M2a-Magnum™ system displays 20 to 100 times the wear resistance of traditional polyethylene lined hip replacement systems.^1,2 This means there is a greater likelihood that the metal-on-metal hip can outlast the traditional metal and polyethylene hip.

Additionally, the M2a-Magnum™ metal-on-metal hip articulation is designed to more closely replicate the size of a patient's natural anatomy. With much larger head sizes than other metal-on-metal implants, ceramic-on-ceramic implants, or traditional metal on polyethylene joints, the Magnum™ system is designed to provide greater stability and range of motion than other systems.

There are many factors your surgeon uses when recommending metal-on-metal hip implants. Only your orthopedic surgeon can determine if you are a candidate for this system or if another type of implant would better address your unique situation.
