I am casting a wider net than with my previous post. Does anyone on this forum have any experience with a polyethylene on metal hip resurfacing implant? I have been unable to find much current information. Any info is appreciated! Thanks!
I have a metal on polyethylene thr I got after my misaligned mom bhr failed. I wish those were available when I got mine done 6 years ago. Since my bhr was never right it's not a fair comparison, but I never had any clunking or knocking sensations like I did with the metal on metal bhr. So far it's been butter smooth... (8 months in knock on wood) From my perspective a metal on poly resurfacing seems like an awesome way to go. If I have to do my other side I would strongly consider one, whatever that's worth.
I just thought I would mention that, from what I understand, the main problem with metal on polyethylene is osteolysis http://en.wikipedia.org/wiki/Total_hip_replacement#Osteolysis (http://en.wikipedia.org/wiki/Total_hip_replacement#Osteolysis) which leads to aseptic loosening. I could be wrong, but it is my impression that this problem happens in most cases (by about 15 years after the replacement) and occurs even more rapidly for younger, active patients. It may be that newer, harder types of polyethylene work better in this respect, I don't know, but this problem is an important consideration for these types of implants.

Hi
Dr. Pritchett uses the poly/metal hip resurfacing device. You can find info on his website
http://www.pritchettorthopedics.com/ (http://www.pritchettorthopedics.com/)
Here is his page on my website with info

Good Luck.

Thanks Pat. In particular, this article you put up by Pritchard http://www.surfacehippy.info/pdf/pritchett-women-hip-resurfacing.pdf (http://www.surfacehippy.info/pdf/pritchett-women-hip-resurfacing.pdf) really helped me to understand "the here and now" with respect to hip implants that utilize polyethelyene on metal.
Hi everybody,
I hope this is the right place for my question.
I've seen everywhere that BHR was THE device to use for a hip resurfacing.
My doctor first talked to me about the hip replacement using metal on metal device.
Then, now, I can see that he is considering using uncemented ceramic on highly crosslinked polyethylene.
Am I correct to think that this device is the same used by Dr Pritchett ?
I thought that plastic devices (polyethylene is plastic ;-) ) have been abandoned because of the high numbers of failures.
I'm quite light 70kg, but I plan to go back to an active sport life : martial arts (taekwondo, grapling, jiu jitsu), horse riding ...
I just turned 40 by the way.
What do you think ?
Could you please help me ?
Cheers
Tim Bratten, what is the source of your information concerning osteolysis and metal on poly implants? I had my resurfacing done by Dr. Pritchett in April 2017 (when I was 61) and there was no mention of this. I'll bet the other Surface Hippies on whom Dr. Pritchett operated would say the same. What research or scientific back-up is there for the proposition that this is a problem with metal on poly implants? Thanks.
Guys, the hip resurfacing high failure rates were from decades ago when they tried to use the first generation poly. Since highly cross-linked poly has been discovered, the poly wear problem is no longer an issue.
