Researchers Call For Ban On Metal-On-Metal THR

Share Article

Bernstein Liebhard LLP reports on a new study calling for a ban on metal-on-metal THR devices based on their high early failure rates.

Bernstein Liebhard LLP reports on a new study published on March 13, 2012 in The Lancet, a British medical journal, concluding that metal-on-metal total hip replacements (“THR”) are more likely to fail than other hip devices, and should therefore be banned*. Researchers analyzed data from the National Joint Registry of England and Wales, the world’s largest database on hip replacements, which included more than 400,000 patients who received a hip replacement between 2003 and 2011. Of the 31,171 individuals who received metal-on-metal THR during that time, 6.2 percent required revision surgery within five years – about a third higher than patients with ceramic or plastic implants. Researchers also concluded that total hip replacement complications were more common in patients who received larger-head implants; women are also more likely to experience total hip replacement complications than men. Lead researcher Ashely Blom, from the University of Bristol, concluded “Metal-on-metal stemmed articulations give poor implant survival compared with other options and should not be implanted.”**

Recommendation To Ban Metal-On-Metal THR Issued On Heels Of Health Alert

The release of these latest findings comes on the heels of a British health directive, advising patients to undergo annual testing for as long as they have a metal-on-metal device to ensure that they are not suffering from tissue damage or other complications.*** Specifically, the Medicines and Healthcare Products Regulatory Agency (“MHRA”) recommended that metal-on-metal hip recipients should have yearly blood tests to check for metal ion levels. If heightened metal levels are detected, patients should have a magnetic resonance imaging scan (“MRI”) in order to detect possible damage caused by metallic debris.    

Safety Concerns Over Metal-on-Metal Total Hip Replacement Complications Continue To Mount

In August 2010, DePuy Orthopaedics, a subsidiary of Johnson & Johnson, issued a voluntary worldwide recall of its ASR hip implant systems, after receiving data from the National Joint Registry of England and Wales that 1 out of every 8 patients (12%-13%) who received the ASR hip implants had to undergo revision surgery within five years of implant.**** In the wake of the DePuy ASR hip recall, metal-on-metal hips have been widely-criticized. Ironically, the impetus for the 2010 recall was based on data from the same registry, which was used by the study’s researchers who are now calling for a ban on all metal-on-metal THR.

The DePuy hip replacement lawyers at Bernstein Liebhard LLP have been involved in lawsuits concerning metal-on-metal THR since the ASR recall in August 2010. The firm is actively filing cases on behalf of individuals who have been implanted with either or both types of artificial metal-on-metal hip implants manufactured by DePuy. The lawsuits allege that the ASR hip replacement and the metal-on-metal Pinnacle hip replacement systems were defectively designed. Bernstein Liebhard LLP is filing cases in the following actions: In re: DePuy Orthopaedics, Inc. ASR Hip Implant Products Liability Litigation (“MDL No. 2197”), which is currently underway in the U.S. District Court for the Northern District of Ohio and In re: DePuy Orthopaedics, Inc. Pinnacle Hip Implant Products Liability Litigation (“MDL No. 2244”), which is currently underway in the U.S. District Court for the Northern District of Texas.
