Dangers of Chromium and Cobalt Ion Exposure in Metal-on-Metal Hip Replacement

Posted in DePuy Hip Replacement, Stryker Hip Replacement

A recent study conducted by Wolf-Christoph Witzleb et al. focused on the implications of the metal ions released through the expected corrosion that occurs after a metal-on-metal hip replacement or hip resurfacing.  Two of these metal ions, cobalt and chromium are known to have carcinogenic and mutagenic effects in patients with metal-on-metal hips, leading to higher risks of cancer and systemic toxicity.

The study investigated the effects of chromium and cobalt emissions from Birmingham hip resurfacing arthroplasty (BHR) and cementless (metal-on-metal) total hip replacement over the first two years after implantation.  The researchers observed that the concentration levels of both cobalt and chromium were significantly higher in those with metal-on-metal total hip replacements and with BHR operations than in the control subjects.  This indicates that the adverse effects of chromium and cobalt on patients who received metal-on-metal hip replacements or BHR hip resurfacing are more likely to occur than for patients who receive other means of hip repair.

A number of metal-on-metal hip replacement lawsuits have been filed because of the use of these risky and unpredictable procedures which may lead to adverse effects as extreme as cancer.  Our lawyers are able to help you or a loved one determine if you could have a claim because of the use of BHR or full metal-on-metal hip replacements in the repair of hip joints.  Contact us today for a free consultation.
