Effect of using Nano-particles of Magnesium Oxide and Titanium Dioxide to Enhance Properties of Hip Joint Bone Cement

Abstract

This paper studies the effect of adding Magnesium Oxide (MgO) and Titanium Dioxide (TiO2) nano particles to enhance the properties of hip joint bone cement. Related to previous work of enhanced bone cement properties by using MgO and TiO2, samples of composite bone cement using three different ratios (0.5%, 1% and 1.5%) w/w of MgO and TiO2 were prepared to calculate the best enhancement ratio. Hardness, compression and bending tests were calculated to check the mechanical properties of pure and composite bone cement. The surface structure was studied using Fourier transform infrared spectroscopy (FTIR) and Field emission scanning electron microscopy (FE-SEM). Setting temperature, porosity and degradation were calculated for each specimen ratio to check values match with standard range of bone cement. Results show remarkable improvement for mechanical and surface structure properties with acceptable changes in FTIR, setting temperature, degradation percentage and bending test relative to pure bone cement.
