Improved bone cement compositions and method of fixing a prosthetic implant to a bone using said improved bone cement compositions. More particularly, bone cement compositions having enhanced fatigue strength and consequently an increased projected service life when placed in a patient to fix a prosthetic implant securely in place. Specifically, bone cement compositions comprising a conventional poly[(methyl methacrylate)-styrene] copolymer based bone cement consisting of a liquid component and a dry powder component, and poly(butyl methacrylate) powder wherein at least a trace but no more than 5 wt % of the dry powder component is replaced by an equal mass of the poly(butyl methacrylate) powder. |
