- M2a-Magnum Metal-on-Metal Hip
Traditionally, hip replacement implants feature a metal ball that moves against a polyethylene (plastic) cup. Metal-on-metal hip replacements feature a metal ball that moves against a metal cup. This metal cup is what provides the additional resistance to wear.
Metal-on-metal components have been used and studied in orthopedics for over 35 years. When polyethylene components were introduced, most manufacturers moved away from all-metal components. However, newer manufacturing technologies and the desire to improve wear capabilities have created renewed interest in metal-on-metal components. Research has demonstrated the following advantages of metal-on-metal components:
- Wear Reduction - In laboratory testing, all-metal components demonstrated a 99% reduction in wear over conventional polyethylene components.1
- Large Heads Provide Potentially Greater Motion, Stability - Biomet's M2a-Magnum Metal-on-Metal Hip has a wide range of size options. The size options allow surgeons to choose the largest possible implant for each patient.
- Large heads (ball portion of implant) potentially provide greater resistance to dislocation and improved implant stability.
- Biomet's M2a-Magnum metal-on-metal hip system has been carefully designed to provide maximum range of motion, offering the potential for over 160 degrees range of motion.1
- The M2a-Magnum hip's large range of sizes allows for better replication of a patient's anatomy. Only metal-on-metal components allow the largest heads throughout the entire range of implant sizes. No matter what your physical stature, the M2a-Magnum system will allow you to benefit from large heads.
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.
If you have questions regarding the M2a-Magnum Hip, please speak with an orthopedic surgeon or search for an orthopedic surgeon in your area.
Only an orthopedic surgeon can determine what treatment is appropriate. Individual results of total joint replacement may vary. The life of any implant will depend on your weight, age, activity level, and other factors.
