The fracture properties of bone cement are strongly influenced by the complex interactions between the residual monomer and components of the media surrounding the bone cement. The aim of this study was to eliminate the influence of the residual monomer by fully curing the cement prior to storage in air, water, lipid or Ringer's solution at room or body temperature for up to 18 months. Subsequent mechanical testing indicated that initially there was a significant increase in the work of fracture values for all the samples stored in the fluid media. With longer-term storage periods a decrease was observed; this was attributed to the process of physical ageing. The removal of the residual monomer eliminated the monomer: lipid interaction, consequently the effect of the storage in lipid was similar to that observed for the other fluid media.
