Abstract

The paper presents the results of rheological tests for three commercial acrylic bone cements currently used in total hip replacement . Moreover, twelve experimental formulations of acrylic bone cements were realized, by partially replacing the methyl methacrylate (MMA) from the classical liquid monomer phase with a new monomer and their rheological properties were evaluated and compared with the commercial bone cements. Thus, the efficacy of acrylic bone cements as anchoring materials as well as their handling and curing properties were estimated. The new formulations exhibited higher elasticity, lower dynamic moduli and clear shear-thinning behavior proving to be potential replacements for classical acrylic based bone cements.
