I received an email from Tom Phelan from the McMinn Center announcing
the press release below by Mr. McMinn. This can also be found on Mr.

Metal-on-Metal Implants – Addressing the Negative Press
have been receiving phone calls following recent press reports on
failed metal-on-metal hip implants. We understand these sensationalist
stories may cause anxiety among some patients. However, we would like to
reassure our patients that these reports mostly concern failures with
the DePuy ASR and the DePuy ASR XL, not the Birmingham Hip Resurfacing
Many press reports imply these failures relate to all
metal-on-metal hip resurfacings. A patient featured in a recent Daily
Mail article, like many others, had a failed ASR. A critical point,
omitted from the print version of the Daily Mail, can be found in the
full on line version. As well as her ASR, the patient had a BHR on her
other hip. She comments, "I’ve never had a minute’s trouble from the
Birmingham hip – if only I’d had it on both sides."
rates with the ASR and ASR XL have been widely documented. Both devices
have now been withdrawn from the market. Research indicates the side
effects, such as muscle damage, are specific to the ASR and do not apply
to the BHR which is a very different device.
Earlier this week,
the MHRA (Medicines and Healthcare products Regulatory Agency) issued
another statement about metal-on-metal hips, in which they say, "On the
evidence currently available the majority of patients implanted with
metal-on-metal hip replacements are at low risk of developing any
In addition to the MHRA’s guidance, we wish to
emphasise that Mr McMinn’s results with the BHR show a 97% survival in
men and women of all ages at 14.5 years. Furthermore, excellent results
with the BHR have been documented in National Joint Registers from
around the world.
Sadly, these ASR failures come as no surprise.
Mr McMinn has been warning about the device since it went to market in
2003. You can see Mr McMinn’s argument against the ASR here http://www.mcminncentre.co.uk/research-lectures-debate.html.
Furthermore, The McMinn Centre has put together several resources which
address patients’ concerns and the differences between the ASR and BHR
designs. These resources are as follows:
• The McMinn Research
Team’s detailed response to list of questions on metal-metal implants
& metal ions provided by hip resurfacing users here
• The McMinn Centre’s response to a Channel 4 documentary on metal-metal hip replacements here http://www.mcminncentre.co.uk/metal-ions-questions-answers.html
• An interview with a patient who has now had his McMinn metal-metal hip resurfacing for 20 years here
If you do have any concerns, please call The McMinn Centre on 0121 455 0411.
