Metal-on-metal bearings in hip resurfacing arthroplasty have been associated with prolonged periods of elevated metal ion circulation in the bloodstream. Specific ions, such as chromium and cobalt are known to be particularly threatening to the general health of the patient, often times leading to symptoms associated with metal toxicity. A recent study focused on the untested variables that may affect the metal ion levels of patients who undergo metal-on-metal hip resurfacing procedures.
The study, conducted by Nicholas Desy, et. al. focused primarily on surgical factors that may have an effect on the patients immediate and prolonged metal ion levels following metal-on-metal hip arthroplasty. The results indicated that a smaller implant diameter, larger cup inclination, and lower postoperative functional scores are associated with increased metal ion levels for both cobalt and chromium following metal-on-metal hip resurfacing. This research suggests that increased metal ion levels following metal-on-metal arthroplasty might be the result of not only the hardware used but also the judgment and effectiveness of the surgeon both before and during the procedure.
If you have suffered from any of the symptoms associated with high metal ion levels following metal-on-metal hip arthroplasty, then you may be entitled to compensation if it is determined that your experiences was the result of faulty hardware or surgical neglect.
