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/sec, the mean simple shear strength of the cement was 251.65 (± 3%) for both 30 sec and 2 min kneading times. Increasing the loading rate to 10-1 rad/sec increased the simple shear strength of 326.20 kg/cm2 (± 2%). The geometric configuration of the acetabular hole configuration did not significantly affect the maximum shear load carrying capabilities of the methylmethacrylate.
