The Food and Drug Administration has been concerned enough about the numbers of people with hip implants who have suffered metal poisoning, to ask manufacturers of these implants to study the effects of metal levels in the body.
Earlier this month, the Food and Drug Administration sent a letter to at least 20 implant manufacturers, including Johnson & Johnson, Zimmer Holdings Inc., Biomet Inc. and Stryker Corporation, asking them to test the levels of metals, including cobalt and chromium, in patients for at least eight years after implantation of these devices.
Manufacturers of metal hip implant devices have been under increased scrutiny over the past couple of years. Johnson & Johnson, in particular, faces a number of hip implant lawsuits related to the high risk of revision surgeries from its two best selling hip implants manufactured by Johnson & Johnson’s subsidiary, DePuy Orthopedics. Approximately 9 months ago, DePuy announced the recall of the hip implant devices after these had been implanted in more than 90,000 patients across the globe. During the recall, DePuy admitted that a study conducted in the United Kingdom had revealed a high risk of revision surgeries in patients that have been implanted with these devices. In some cases, the risk of the implants failing, leading to revision surgeries was as high as 12%. Other than Johnson & Johnson, Stryker and Zimmer are two of the biggest implant manufacturers in the industry.
California pharmaceutical liability attorneys have seen some signs that the Food and Drug Administration is beginning to take the health risks from these implant devices more seriously. Earlier this year, the agency dedicated a section on its website to explain the health risks of these devices. Among the health concerns that the agency mentions on its website is that some of the patients who have been implanted with these devices have been diagnosed with high levels of metal ions in the bloodstream, possibly leading to complications of the heart, nervous system and thyroid gland.
