Metal-on-Metal Hip Replacements
Several studies have warned about an increased risk of problems with metal-on-metal hip replacements. Patients with metal-on-metal hip replacements manufactured by Depuy Orthopaedics, Johnson & Johnson, Zimmer, Stryker, Biomet, Wright Medical Technology and other companies may experience pain, tissue damage or other symptoms caused by metal fragments from these devices.
Concerns about the safety of metal-on-metal devices were raised in April 2010, when a British health agency published a report about problems with these devices. The agency warned that patients with a metal-on-metal hip replacement could experience damage to the soft tissue at the site of the implant caused by loose metal fragments. These particles could cause pain or other symptoms and require surgery to repair the hip replacement.
In May 2011, the Food and Drug Administration asked 21 manufacturers of metal-on-metal hip implants—including DePuy Orthopaedics, Stryker, Zimmer, Biomet and Wright Medical Technology—to conduct a safety review of these products. The agency said that some patients with metal-on-metal devices could experience heart, thyroid or nervous system problems from elevated levels of cobalt or chromium in the bloodstream.
Studies have found that patients with metal-on-metal hip replacement may have higher levels of metal in the bloodstream. According to researchers at the University of British Columbia, patients with Zimmer hip replacements had 2.6 times the normal level of chromium in their bloodstream and 10 times the normal level of cobalt.
