My email address is [email protected] I am compiling a list of the 21 companies who manufacture/market metal on metal hips. If you know the names of any of these companies please email them to the address above. So far I have Depuy, Zimmer, Biomet, and Pinnacle. Thanks for your help!!!

I received a Depuy ASR XL Acetabular hip and had to go through revision surgery just 4 years later. I am doing extensive research on MOM hips and am trying to put together a list of all the companies who manufacture and market these devices. I have read in several articles about the FDA mandate to the 21 companies who manufacture MOM hips but I can't find a list of who these companies are. Any help would be greatly appreciated. Thank you.

Dr. Berend is correct. Variation in product designs, tolerances, material processing and manufacturing as well as implantation methods can significantly impact product durability and performance over time. It may be unrealistic to expect a manufacturer to physically test their products for every possible combination of design, tolerance, material, etc due to cost and time limitations. An alternative is to use virtual testing and simulation to predict product performance under varying conditions. One company providing these virtual simulations today across multiple industries is VEXTEC – check it out at www.vextec.com.

Companies pushed sales of MoM because of the higher margins - period!

Katie- I was unable to find the report on ECRI's site. I saw the report in ECRI's "emerging technology brief" free monthly email. You could join that list on their site.

The sales agents of the manufacturers had something to do with the overuse of these devices, and these people were in turn trained and compensated by the manufacturers. Also, as was noted in the article, all metal-on-metal systems are not not identical, and the strategic emphasis on quality systems also differs among manufacturers. This is a complicated situation, and pinning the blame on this mess onto the 510(k) premarket clearance system (e.g. Consumers Union) does not help avoid problems such as these.

Can you provide a link to the report from the ECRI Institute?
