Demand the FDA do its job and recall the Biomet Magnum and M2a-38 metal on metal hip replacements. Why? Because these hip replacements are causing heavy metal poisoning resulting in tissue destruction, pseudotumors, bone deterioration, and heart failure. Patients and surgeons have been left in the dark. Zimmer-Biomet has known of these problems for years. The company even recalled these hip replacements in other parts of the world, but not here. Zimmer-Biomet has failed to warn patients and surgeons in the United States of the heavy metal poisoning. Demand the FDA do its job and recall this dangerous product. Patients and surgeons must be warned of the risks!
