Mass General Center for Metal-on-Metal Total Hip Replacement

Over the past several years, troubling information has surfaced about the seriousness of and the incidence of adverse reactions to metal-on-metal (MoM) total hip replacements, which have been widely used to treat young and active patients with significant hip arthritis. Such complications are relatively rare as the vast majority of patients with this type of hip replacement do well. However, reports of these complications are increasing.

In Great Britain, a medical alert has been issued calling attention to this problem. In the United States, the FDA has released a statement of concern and the American Academy of Orthopaedic Surgeons has issued follow up statements concerning both the British and the FDA alerts. FDA has recently informed all implant manufacturer of MoM THR who market implants in the USA that they are now required to survey all their MoM THR patients.

Some patients with MoM hip replacements develop unexplained pain, and in the majority of cases, conventional pre-operative tests (plain radiographs and standard blood tests) do not reveal any abnormality. Thus, the ordinary follow up evaluation may be of limited value. Therefore, we have established the Center for Metal-on-Metal Total Hip Replacement at the Mass General. The mission of the Mass General Center for Metal-on-Metal Total Hip Replacement is to provide excellence in clinical care to MoM patients by integrating various specialized tests (analysis of blood samples for metal ions, and imaging studies) in order to establish if an adverse reaction to MoM THR implants is present and to formulate the best way to treat these problems. Therefore, the Center brings together the multi-disciplinary expertise that exists at the Department of Orthopaedic Surgery and the Harris Orthopaedic Laboratory to provide state-of-the-art comprehensive care to patients with metal-on-metal total joint replacements and conduct cutting-edge research. Our physicians and researchers strive to transform basic discoveries into clinical practice and provide critical evaluation for and specific advice for patients with metal-on-metal implants.
