  7. 35. Evaluation of methods of measuring wear of polyethylene acetabular components intotal hip arthroplasty

    Författare :Charles R Bragdon; Göteborgs universitet; []
    Nyckelord :Total hip replacement; polyethylene; wear; radiostereometric analysis; radiograph;

    Sammanfattning : Background: The introduction of highly cross-linked, wear resistant polyethylene acetabularcomponents for clinical use in total hip replacements has intensified the interest in and need for highlyaccurate methods of measuring wear from clinical radiographs. There are several methods currentlyavailable for measuring the relative displacement of the femoral head into the acetabular componentresulting from the combination of plastic deformation and wear of the polyethylene bearing surface.
