Biomet M2a-Magnum Metal-on-Metal Hip Replacement
The Biomet® M2a Magnum metal-on-metal hip joint replacement devices are intended for use in non-cemented primary and revision hip joint replacement procedures. The large metal head consists of a CoCrMo (cobalt, chromium, and molybdenum) alloy, three metals that have been used in medical devices for years. The porous coating and taper adapter consist of a titanium alloy believed to aid in bone growth.
According to Biomet, the large head design, along with the alloy, is designed to lead to less wear and corrosion and a smaller volume of debris, which allows a greater variety of sizing options, including larger heads. Larger heads yield greater range of motion and stability, resistance to dislocation, and a better match to each individual patient’s size and stature.
Biomet M2a-Magnum Surgical Options
The Biomet devices can be used in traditional hip replacement surgery. Biomet also worked with a team of surgeons to develop specialized instrumentation and surgical technique to aid in the implantation of their device. The Biomet Anterior Supine Intermuscular (ASI) technique builds on traditional minimally invasive surgery, which allows surgeons to directly approach the hip without having to cut through the surrounding muscles and/or tendons in the process.
