Metal sensitivity causing loosened joint prostheses.
Metal sensitivity, as measured by an in-vitro assay on peripheral blood lymphocytes, was evaluated in patients with failed joint prostheses. Lymphocyte transformation to chromium, cobalt, and nickel was measured in 24 patients having revision surgery for a painful or loose prosthesis and compared with that in 11 patients who had a successful hip prothesis in situ for at least 2 years previously...
متن کاملIncidence of metal sensitivity in patients with total joint replacements.
Sensitivity to chromium, cobalt, nickel, molybdenum, vanadium, and titanium was studied by patch tests in 50 patients who had received total joint replacements. Nineteen (38%) were sensitive to one or more of the metals. In 23 patients non-traumatic failure of the prosthesis had occurred, and 15 of these patients were sensitive to metal. Out of 27 patients with no evidence of prosthesis looseni...
متن کامل[Upper ankle joint prostheses in haemophilia patients].
UNLABELLED Secondary arthrosis of the upper ankle joint (talocalcanean joint) is one of the most frequent forms of haemophilic arthropathy. It is a secondary form of arthrosis not only because of chronic synovitis and cartilage injury resulting from chronic recurrent intraarticular bleeds, but also due to the misalignment of the joint and abnormal joint stress. The consequences are manifest eve...
متن کاملCobalt and chromium measurement in patients with metal hip prostheses.
Approximately 1 million metal-on-metal (MoM) hip prostheses have been implanted worldwide to alleviate pain, restore hip function, and improve overall quality of life. These implants contain femoral and acetabular bearing surfaces that are typically composed predominantly of cobalt (Co) and chromium (Cr). Although the majority of MoM hip replacements have been successful, multiple recent report...
متن کاملMetal sensitivities and orthopaedic implants revisited: the potential for metal allergy with the new metal-on-metal joint prostheses.
The potential of metal-containing orthopaedic prostheses to induce problems through metal allergy taxes dermatologists and orthopaedic surgeons alike. Metal-on-plastic joint replacements are not thought to induce metal allergy but wear products, principally polypropylene particles, produce a foreign body reaction in bone and may lead to aseptic loosening of the joint. Orthopaedic surgeons are i...
