Biological Effects of Wear Particles from Metal on Metal Hip Protheses (Relevant to DePuy ASR Hip Implants)

In 2008 the Institute of Medical and Biological Engineering at the University of Leeds published a study on the metal particles released from metal on metal hip protheses (implants).

This study was concerned with the release of Cobalt and Chromium particles, particles which are also tested for when seeing if the DePuy ASR hip replacement or resurfacing systems have failed.

This study found that hip implants made with Cobalt and Chromium have the potential to release metal ions, which may be toxic to cells, induce deoxyribonucleic acid (DNA) damage or cause the patient hypersensitivity.

The wear of metal on metal hip implants is dependant upon the design and in particular the carbon content of the alloy, the radial clearance and the head diameter.

DePuy have voluntarily recalled their ASR hip replacement and resurfacing system which have been in circulation since July 2003. However, the importance of this study confirms the need to have regular blood tests to ensure that your metal on metal hip implant is functioning properly. This is particularly important if you have received a DePuy ASR hip replacement or resurfacing system since July 2003.

If you have any concerns on whether your metal on metal hip implant is functioning properly you should seek medical advice from you operating surgeon, hospital or GP.

If you have experience adverse symptoms with your DePuy ASR hip implant or other metal on metal hip implant please contact the product liability team at Garden House Solicitors on 01992 422 128 or send us an email at kevin@gardenhousesolicitors.co.uk .
