title: Low- versus high-viscosity bone cement. Fixation of hip prostheses analyzed by roentgen stereophotogrammetry.
abstract: Sixteen patients were examined by roentgen stereophotogrammetry during the first year after total hip arthroplasty. Eight prostheses were fixed with low-viscosity and eight with high-viscosity cement. Eight acetabular components, four in each group, migrated cranially, and three femoral components, all in the low-viscosity group, migrated distally. Our findings suggest that low-viscosity cement does not improve prosthetic fixation.
