Fresh concerns about metal-on-metal hip components

Australian National Joint Replacement Registry (ANJRR) publishes 2011 annual report which details startling early revision rates for metal-on-metal hip resurfacing components.

30 September 2011

In August 2010 DePuy Orthopaedics recalled the ASR Hip Resurfacing System after it was found to be associated with unacceptably high early revision rates, linked with pseudo-tumours and metal ion release. The 2011 Australian statistics indicate that other popular Hip Resurfacing Systems are demonstrating similarly high revision rates to the ASR, fuelling growing concerns over metal-on-metal hip components in general.

The 2011 statistics from the ANJRR report that the DePuy ASR component is associated with revision rates of 10.5% at 5 years and 13% at 7 years. Resurfacing systems with similarly high revision rates include the Zimmer Durom, with a failure rate of 7.3% at 5 years and 9.6% at 7 years and the Corin Cormet, with a failure rate 7.4% at 5 years (7 year revision statistics are currently unavailable).

By comparison, the National Joint Registry of England and Wales reported in 2010 that the overall revision rate for primary hip replacements is 2.1% at 3 years and 2.9% at 5 years and the market leader for resurfacing systems has a reported revision rate in the 2011 ANJRR of only 3.5% at 5 years and 5% at 7 years.

Leigh Day & Co has already been approached by over 500 patients concerning a variety of failed hip resurfacing systems. 

If you or a member of your family has been affected by a DePuy ASR or Zimmer Durom hip implant, please call Olivia Anness on 0207 650 1216 to discuss your potential claim.
