Yikes!!! I'm nearly certain this device is similar to the BioPro Tara

device that IS FDA approved. Two things noted in the article-acetabular

component with a plastic liner, and the life expectancy of 5-10 years! The

type of device described in the article is the reason so many OS's call

resurfacing a failure. The large ball size coupled with the plastic liner

leads to lots of poly debris and the osteolytic reaction which causes the

short life expectancy of those type of devices.

A reminder note to all the newbies-the folks on this site are almost

certainly getting/living with one of the three newer generation metal on

metal devices (Conserve Plus, Corin 2000 and Birmingham Hip

Resurfacing). There are others out there that are FDA approved.....doesn't

mean I'd get one....

(no poly in MY body)

I went back and read more of the site-FAQ's are somewhat interesting. They

claim life expectancy of their device from 5-20 years and the same

restrictions as with a THR.

The first page of their blurb that said " metal on plastic

articulation " , made my skin crawl! Also they claim 5-10 years

longevity there. That is in keeping with gross failures that we've

heard about. Can you imagine the osteolysis that huge liner could

cause????

YUK and lots of pain down the road for anyone who gets it.

Some info on the Buechel-Pappas Resurfacing Device & South Mountain

Orthopedic that I picked up in my research on resurfacing. Please

note - THIS IS NOT AN ENDORSEMENT.

The Buechel-Pappas Integrated Total Hip Replacement device is

manufactured by Endotec.

<http://www.endotec.com/pdf_files/res%20thr%20sp%20-%20144.pdf>

The device has a ceramic-coated femoral component and a titanium

acetabular component with a polyethylene bearing insert. It is the

only resurfacing methodology listed as currently approved by the

FDA. (From Alberta Heritage Foundation for Medical Research Tech

Note 33) -

<http://www.ahfmr.ab.ca/hta/hta-publications/technotes/TN33.pdf>

The polyethylene in the acetabular component a ram extrusion-type non-

crosslinked poly (from Orthopedics Today (Guide to Polyethelene in

Joint Implants)-

<http://www.slackinc.com/bone/ortoday/199910/chart.pdf>

Dr. Buechel, & J. Pappas, Ph.D., (professor of mechanical

engineering at New Jersey Institute of Technology) developed the

Buechel-Pappas Total Hip System.

Dr. Frederick F. Buechel, M.D. is the senior orthopedic surgeon at

South Mountain Orthopedic.

Bottom line - it's a plastic bearing.

Good information is power & enables informed decisions.

Carl,

Thanks for giving the links to more information. I still have

questions but it doesn't sound quite as evil as I first thought. I

still say their web site is too vague and confusing. Why do they say

it's a metal/poly articulation?

You're not going to believe this but I totally agree with you on this matter.

Trudy,

You're welcome. I don't know why the news article says metal/poly

articulation - could be the reporter got it wrong.

The poly insert IS a concern. The only advantage I can see with this

system is that it might " buy time " and allow a patient to postpone a

THR (and subsequent revisions) for 5 to 10 years. However, there are

a lot surfers and surfer wannabes on this list who are counting on

their BHR/C+/C2000's to last a lot longer than that.

Hi,

I recently saw a plastic lined knee joint that had had to be removed because

of hassles with the situation. It looked like the mice had been at the

plastic bit. All these joints take huge pressures which is why I feel glad

that my Resurface will be metal on metal.
