I am discussing a study concerning metal-on-metal hips and cobalt-chromium toxicity. A recent study was published in the Journal of Bone and Joint Surgery. In this study, researchers evaluated patients with metal-on-metal hips. They examined the patients for a correlation between blood levels of cobalt- chromium and an incidence of pseudotumors or tissue damage surrounding the hip joint.
The surprising discovery indicated no correlation. Individuals with high cobalt and chromium levels did not always suffer from tissue damage, and the degree of tissue damage did not always correlate to the level of cobalt and chromium in the blood.
The researchers concluded individuals with metal-on-metal hips and high levels of cobalt and chromium do not necessarily need a hip revision. Prior to hip revision, the doctor should also evaluate pain levels and perform more conclusive tests and imaging studies, like MRIs or x-rays. This ensures a detailed description of the hip. The study mentioned many doctors were relying heavily on the cobalt and chromium serum levels alone to perform hip revisions.
