J&J, Hip Makers Asked by FDA for Data on Metal in Patients

The U.S. Food and Drug Administration asked Johnson & Johnson, which is already facing more than 1,000 lawsuits over hip replacements, to study whether its implants raise the level of metal in patients’ blood to dangerous levels.

The FDA on May 6 sent the request to J&J and 20 other device makers, including Biomet Inc., Stryker Corp. and Zimmer Holdings Inc., asking them to study the levels of cobalt and chromium in patients for at least eight years after implantation. The request focuses on all-metal devices whose failure rates have prompted recalls and increased scrutiny from regulators.
