Biomet M 2 a-Magnum®
The Biomet M 2 a-Magnum® is a metal-on-metal (MoM) hip implant device intended to improve mobility and minimize pain in patients with osteoarthritis, severe hip fractures, bone tumors, or other conditions that have not responded to less invasive treatments (such as medication, use of walkers, or physical therapy).
Biomet Orthopedics first introduced the M 2 a line of hip device systems in 1996, and the Biomet M 2 a-Magnum®, which became available in October 2004, is a "large articulation" MoM hip implant that contains some of the manufacturer's latest innovations.
Design of the Biomet M 2 a-Magnum®
Some of the unique features of the Biomet M 2 a-Magnum® include:
- Hemispherical and modular design to maximize mobility and provide optimal clearance of the metal ball within the metal cup
- Increased diameter of the metal head to reduce the possibility of joint dislocation
- PSS® coating to improve stability and minimize wear
- Specially formulated metal alloy (specifically CoCrMo alloy, which is primarily composed of Cobalt, Chromium, and Molybdenum) that minimizes friction
- Various size ranges to more accurately be able to fit the hip implant devices to an individual patient's anatomy.
Biomet M 2 a-Magnum® - Important Patient Risk Information
Despite the fact that Biomet has incorporated various technological advances in its cutting-edge M 2 a-Magnum® hip system, these metal-on-metal devices still carry some risk to patients. Patients should be sure they understand all possible risks and contraindications associated with these devices prior to undergoing implantation surgery.
Some of the possible risks associated with the implant include:
- Hip dislocation due to improper placement of the device or awkward movements by the patient after implantation
- Loosening of the device, which can contribute to hip dislocation
- Metallosis, the accumulation of metal ions in the blood due to erosion of the metal alloy used in these devices (if left untreated, metallosis can lead to heart problems, thyroid dysfunction and neurological impairments)
- Nerve and/or tissue damage in the region surrounding the implant
- Osteolysis, bone loss or depletion of bone calcium levels, where bone meets the implant device
- Post-operative infection or allergic reaction
- Shortening of the leg associated with the implanted device
When Biomet M 2 a-Magnum® hip implants experience defects, patients will likely need at least one revision surgery to repair and possibly remove and replace the device. Patients that require revision surgery may be eligible for financial compensation.
