We developed a laboratory model in which 72 open\u2010cell foam specimens were used to simulate bone. Analyses of two cement viscosities, two foam porosities, and six cementing techniques were performed: manual cement application only, manual application and filling of one quarter of the component with cement, filling of half of the component, manual application and half component filling, full component filling, and manual application and full component filling. For manual application, cement was pressurized into the foam by rolling the finger tips. For component filling, a defined quantity of cement was poured into the component before pressing it onto the foam. Specimens were cut into quarters, and cement penetration was quantified in seven areas: top, chamfer, wall, interior area, and proximal, medial, and distal stem. The manual technique showed a 3\u2010mm thick, even cement penetration of the outer fixation surface (top\u2009=\u200926\u2009\u00b1\u20090 mm<jats:sup>2<\/jats:sup>, chamfer\u2009=\u200914.9\u2009\u00b1\u20090.2 mm<jats:sup>2<\/jats:sup>, wall\u2009=\u200955.6\u2009\u00b1\u20095.2 mm<jats:sup>2<\/jats:sup>). None of the other techniques showed a significantly higher penetration in these areas. Large differences were found between all techniques at the medial stem (27.7\u2009\u00b1\u200917.5 mm<jats:sup>2<\/jats:sup>, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and the interior area (128.5\u2009\u00b1\u200969.6 mm<jats:sup>2<\/jats:sup>, <jats:italic>p<\/jats:italic>\u2009=\u20090.013). An increasing degree of penetration occurred from manual cement application to manual application and full component filling. Sixteen specimens showed incomplete seating, which occurred with all techniques except the manual technique. The manual technique consistently gave an approximately 3\u2010mm thick even cement penetration over the outer fixation area. Pouring any cement into the shell resulted in variable degrees of deeper penetration and a risk of incomplete seating, which have been associated with bone necrosis and early fracture. \u00a9 2007 Orthopaedic Research Society.
