Abstract
In the recent years, a magnesium-calcium phosphate materials are considered as an alternative to materials based on the calcium phosphates in the reconstructive surgery. The injectable bone cements have been particular interest for the minimally invasive surgical approaches. The aim of this work is considered to the creating and studying of the structural-phase state of cement materials based on the Newberite phase (MgHPO4·3H2O). The addition of a polymer - sodium hyaluronate in the cement fluid, based on a sodium phosphate solution, leeds to the increasing of the viscosity of the system, thereby increasing the cohesion of cement materials. The effect of addition sodium hyaluronate in the various concentrations on the phase composition, setting time, pH value, microstructure, injectability and strength properties of cement materials has been studied.
