The New York Times is reporting, what we already know–the number of complaints about metal-on-metal hip implants is surging. And there is no end in sight.
“All-metal replacement hips are on a trajectory to become the biggest and most costly medical implant problem since Medtronic recalled a widely used heart device” in 2007. At the present time, the major problems appear to exist be with the Zimmer Durom and DePuy (Johnson & Johnson) ASR metal-on-metal hip implants. But complaints are surfacing with many brands.
Patients are experiencing reactions, believed to be linked to the shedding of metal debris. Unlike traditional hip implants that use a ceramic or metal ball and a poly-vinyl pelvic cup liner, the metal-on-metal components have metal balls and metal cups. Reactions to the metal debris mimmick severe infections and can attack and destroy bone and soft tissue. In the simplest cases, the metalosis causes the components to loosen and after surgical revision, the patients are recovering normal function after revision. However, in some cases, the metalosis has destroyed so much muscle bone and ligament, that normal revision is not possible. These patients can suffer debilitating pain and loss of function.
