Is another hip implant recall going to happen soon?
This week, a team of researchers from Bristol University in England published an article in The Lancet medical journal regarding the safety of metal-on-metal hip implants. They concluded that all metal-on-metal hip implants are unsafe and should not be implanted in patients.
The results of this study clearly show that metal-on-metal hip implants are significantly more dangerous than other types of hip implants, such as metal on polyethylene or ceramic on polyethylene. For example, the data showed that even when the recalled ASR implants were excluded, all other metal-on-metal articulations still had a five-year revision rate of 6.2%. They concluded that metal-on-metal implants fail more quickly and a a much higher rate than any other type of bearing surface.
The data also showed that metal-on-metal hip implants are more dangerous in women than in men. However, both men and women have higher revision rates with metal-on-metal implants than any other type of bearing surface.
As a result of this research, the authors concluded that:
Metal-on-metal stemmed articulations give poor implant survival compared with other options and should not be implanted. All patients with these bearings should be carefully monitored, particularly young women implanted with large diameter heads.
The Lancet is one of the oldest and most respected peer-reviewed medical journals in the world, and many doctors look to it for guidance on the latest scientific developments.
The data from this study provides even more evidence that DePuy’s Pinnacle metal-on-metal hip implant should be recalled. We believe this implant is unsafe and has injured thousands of people. So far, more than 1,000 lawsuits have been filed against DePuy alleging injuries caused by the Pinnacle hip implant. Nevertheless, the FDA has not yet forced DePuy to recall this product.
We hope that the latest article regarding the dangers of metal-on-metal hips will help educate doctors about the risks of these devices so that they can provide the best treatment options for their patients. We also hope that this data causes the FDA to finally pay attention to the risks of these implants and force the manufacturers of all metal-on-metal hips to recall their products from the market.
