Metal-on-metal hip implants are more likely to fail than devices made from other materials and should be banned, U.K. researchers said after reviewing the world’s largest database on hip replacements.
More than 500,000 patients in the U.S. and 40,000 in the U.K. have metal-on-metal hips and are at higher risk of device failure, according to the analysis, which was published today in The Lancet. Failure rates were as much as four times higher in women, who are likelier to have implants containing a larger prosthetic femoral head.
