Abstract


The paper presents method of determining modulus of elasticity in mechanical compression testing of bone cement. The results of investigation of mechanical properties of bone cements from different manufacturers under the compression test and the dependence of the strength and stiffness parameters on the exposure time after polymerization. The study found that all four brands of studied bone cements comply with regulatory requirements of State Standard ISO 5833-2011, and bone cement Cemex Rx has the best combination of properties.


Keywords
