Earlier this month the FDA did not give Zimmer Holdings, Inc. permission to market a spine stabilization system that they call a Dynesys device as a stand alone product.

While it has not gotten the same news coverage, issues on zimmer durom cup have been raised in courtrooms and on the internet with some experiencing problems after having a durom cup hip replacement.
Law firms such as Maglio Christopher Toale & Pitts have filed cases in court and have provided information on the exact zimmer durom cup types that have been at issue. Apparently there is a different model that was not used in the United States that did not have some of the same failure rates.
What is interesting about this scenario is that the media is not doing any real reporting on the problems that have been reported, it has been some of the law firms that have actually provided more reference material. Which at least means those googling are discovering there could be a problem...
