For the patient, this test involves just two non-invasive examinations. Young-Min Kwon, one of the Directors of the Center, in conjunction with colleagues at the University of Oxford, England, developed a test of walking, sitting and climbing stairs that may detect and measure edge wear. When edge-loading occurs in the metal implants, this leads to accelerated metal wear and increased metal ion levels in the blood.ĭr. Because the most serious problems of MOM THR come from wear of the metal parts and because the most serious wear occurs at the edge of the metal parts creating a chisel-like effect, this major wear is called “edge wear”. In selected patients, a research study involving a specialized motion analysis will be performed. Analysis of the Metal Ion Levels in the Blood The special tests include the followings: A. The treatment recommendations may range between further close monitoring and reoperation surgery. Based on reviews of these tests, a treatment plan will be formulated which is tailored to each individual patient. In conjunction with the detailed assessment by one of our expert hip surgeons, a number of special tests will be done in addition to the usual standard x-rays. The mission of Mass General Center for Metal-on-Metal Hip & Tribocorrosion Evaluation & Treatment 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. Thus, the ordinary follow up evaluation may be of limited value. In the majority of cases, conventional pre-operative tests (plain radiographs and standard blood tests) do not reveal any abnormality. Our physicians and researchers have transformed basic discoveries into clinical practice and provide critical evaluation for and specific advice for metal-on-metal implants.īecause some patients with Metal-on-Metal (MoM) hip replacements develop unexplained pain, and because a few develop abnormal tissue reactions to the wear of the implants and require a reoperation, we established a Center that patients could rely on for comprehensive clinical evaluation. The Mass General Center for Metal-on-Metal Hip & Tribocorrosion Evaluation & Treatment provides state-of-the-art comprehensive care to patients with metal-on-metal total joint replacements and conducts cutting-edge research. Our doctors and scientist teams are specifically trained in issues specific to metal-on-metal implants and have won international awards for their work. The Center provides comprehensive clinic care for patients by formulating customized treatments by integrating state-of-the-art testing and analyses. Billing, Insurance & Financial Assistance.
