One of the factors influencing initial fixation of total hip arthroplasty with bone cement is cement pressure° Cement mantle pressure is thought to change with the shape of a stem, the roughness of the stem surface, and the thickness of the bone cement layer. This in vitro study examined cement pressurization during the insertion of femoral stems, namely PERFECTA (PER) and ANCAFIT (AFJ) stems, into seven pairs of human cadaver femorao Cement pressures were measured at proximal and distal stem levels during the insertion of each stemo AFJ with a thin cement layer showed greater cement pressures than PER with a thick cement layer at both proximal and distal stem regions. Distal stem levels appeared to show greater pressures than proximal levels for both AFJ and PER.
