Wp. Yau et al., The performance of three vacuum-mixing cement guns - a comparison of the fatigue properties of Simplex P cement, INT ORTHOP, 25(5), 2001, pp. 290-293
We tested three commercially available cement-mixing systems (Howmedica, Su
mmit and Stryker). After mixing the cement was allowed to cure in metal mou
lds under standard conditions. Sixty-nine cement blocks were produced. The
fatigue behavior of the blocks was tested until failure. A wide scattering
of results was observed in all the three systems. Uneven mixing of the poly
mer and monomer was observed in the Howmedica system. A significantly stron
ger cement (P = 0.018) was produced with the Stryker system.
