Abstract
An investigation of the effect of kneading time on the simple shear strength of cold-cured plain methylmethacrylate bone cement and on the effect of anchor-hole configuration on the load-carrying capabilities of the cement anchor-hole configuration demonstrates that at a strain-rate of 10-3 rad/second, the mean simple shear strength of the cement was 251.65 (plus or minus 3%) for both 30-second and 2-minute kneading times. Increasing the loading rate to 10-1 rad/second increased the simple shear strength of 326.20 kg/cm-2 (plus or minus 2%). The geometric configuration did not significantly affect the maximum shear load-carrying capabilities of the methylmethacrylate.
