There have been many lawsuits involving hip replacements: Zimmer, Stryker, and DePuy have all been in the scopes of plaintiffs’ lawyers. But a bigger problem might be looming: metal-on-metal hip implants. In the last few years, metal-on-metal hip implants have been used in approximately one-third of the replacements performed annually in this country. What is the problem with metal-on-metal hip implants?
Doctors clearly don’t fully understand the problem yet. But studies are leading some doctors to conclude that the problem manufacturers may have underestimated is the degree to which metal on metal causes the release of microscopic ions of chromium and cobalt.
The body fights back against these metals, causing a reaction called metallosis that compromises the immune system. Inflammatory reactions to the metal can cause groin pain, fatigue, death of tissue in the hip joint, loss of surrounding bone and muscle, and…. who knows what else? There is also speculation it may cause heart and kidney problems as well. Metal-on-metal hip implants are still relatively new, so we don’t really know what the long-term consequences may be.
