Recent Medical Study finds Metal-on-Metal Artificial Hips have High Failure Rates

“Beyond the well-publicized recall of the Depuy ASR metal-on-metal hip implant, this study casts doubt on the safety and efficacy of all metal-on-metal implants. An FDA recall or ban of these devices could be imminent.”

A new study released in The Lancet, one of the world’s leading medical journals, concluded that metal hip replacements have a dramatically higher failure rate than other types of artificial hip devices. This study has created safety concerns and prompted a call for a ban. British medical regulators had previously warned the public, and approximately 50,000 Britons with all metal hip implants, of newfound dangers associated with these implants.

On February 28, 2012 the United Kingdom’s Medicines and Healthcare Products Regulatory Agency (MHRA) announced that patients with metal-on-metal hip implants should get yearly blood tests. Evaluating cobalt and chromium levels, such tests would determine if these implants were producing dangerous amounts of toxic metallic debris. Click here to read this press release.

Accumulation of metal debris from implants can cause tissue damage, cysts and pseudo tumors, cause premature device failure, necessitate subsequent revision surgery and result in other long term health problems.

Analyzing data from over 400,000 hip replacement cases between 2003 and 2011, the Lancet study found that patients with all-metal hips had a 6.2% probability of requiring a replacement within 5 years. These failure rates were up to four times greater in larger-head implants and in those devices used for women. Click here to read the BBC news article.

The widespread use of metal-on-metal hip implants continues in the United States, while the use of such devices continues to decline in Britain. Estimates show over 500,000 patients with these metal-on-metal devices in this country. Some manufacturers of metal-on-metal devices:
