In this work the possibility to improve injectability of α-tricalcium phosphate (α-TCP) bone cements using citrate ion containing additives was investigated. It has been ascertained previously that both composition of setting solution and α-TCP powder pre-treatment can significantly alter the setting process. The most suitable cement compositions for injectable cements are cements with basic liquid phase pH (pH 8 and higher). Addition of citrate ions to a basic liquid phase does not significantly affect injectability, but shortens setting time and thus improves cement cohesion.

Keywords
