Among those 20 makers of artificial hip being requested by the U.S. Food and Drug Administration (FDA) to take up studies whether its implants raise the level of metal toxicity in patient’s blood to dangerous levels is the Johnson and Johnson, as stated on the Bloomberg News website.
The New York Times website says that it was an unusual move of FDA because of alarming reports about hip implants being linked to high, early-failure rates and severe health effects in some patients. An alternative of hip replacement has been considered in hip impingement surgery.
Johnson & Johnson which received more than 1,000 lawsuit over hip replacements was requested to do a research of the level of cobalt and chromium in patients who have had the implants in at least eight years as mentioned by the Bloomberg News on its website. The appeal is on all-metal devices whose failure rates was alarming which urged recalls and augmented examination from regulators.
FDA spokesperson Karen Riley tells Bloomberg News in an e-mail that the agency was conscious of the public health questions regarding the safety of metal-on-metal total hip replacement systems. There was no sufficient scientific records to specify the concentration of metal in a patient’s body necessary to produce adverse systemic effects.
The request for a thorough study rose after Depuy Orthopaedics, a unit of New Brunswick New Jersey-based Johnson and Jonson, made a recall of about 93,000 artificial hip replacements that was implanted in patients as stated in the Bloomberg News website. Depuy cited unpublished documents from the U.K. national joints registry showing a failure rate of 12 percent within five years.
The New York Times says that metal-on-metal hips in which the ball-and-socket components are made from metals like cobalt and chromium, accounted up until lately for about one-third of the estimated 250,000 hip replacement processes accomplished each year in the United States.
But, over the last two years, the use of the implants has fallen off in part amid reports that they were prone to early failures and that some patients had developed serious health problems related to particles of metallic debris that are shed by the devices as they wear which triggered these patients to file a DePuy pinnacle lawsuit.
