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 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...
متن کاملGene therapy and cement injection for restabilization of loosened hip prostheses.
Loosening of orthopedic hip prostheses is an increasing health problem. In elderly patients with comorbidity,revision surgery may lead to high mortality rates. A less invasive surgical technique is therefore required to reduce these patient risks. To this end a percutaneous gene therapy approach was designed to destroy the periprosthetic loosening membrane, and enable refixing of the hip prosth...
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 کاملTissue reaction around loosened prostheses: a histological, X-ray microanalytic and immunological study.
Tissue reactions at the cement-bone and artificial implant-bone interface were examined light and electron microscopically in thirty-six patients who underwent revisory operation of hip or knee replacement. The reactions were classified into three types: inert tissue, active tissue with giant cell proliferation, and active tissue with predominant foamy cell proliferation. The third type of reac...
