A special test known as a metal ion blood test can determine levels of toxic metal left in the blood stream from metal on metal hip replacements such as the Stryker Rejuvenate and Stryker ABG II hip implants. Patients who received a Stryker hip replacement may be at risk of metallosis, or metal blood poisoning, when the components of the device rub together and leave metal debris in the blood stream.
Normal tests such as x rays and regular blood tests often will not show levels of metal such as cobalt and chromium in the blood stream. An alarming number of Stryker patients have reported side effects including toxic levels of potentially carcinogenic metal in the blood stream due to their hip replacements.
Stryker issued a hip replacement recall for its Rejuvenate and ABG II hip implants after studies found that the devices were failing at a rate much higher than expected. Multiple patients have filed Stryker lawsuits alleging that the company released a defective device that caused serious injuries.
