[Study on the methods of promoting the injectability of calcium phosphate cement].
OBJECTIVE
To study the methods of promoting the injectability of calcium phosphate cement.


METHODS
Evaluation methods of bone cements, injectability and methods of promoting injectability were reviewed by extensive investigating of latest literatures.


RESULTS
It was very important to improve the injectability of calcium phosphate cement. Commonly used methods to evaluate the injectability included testing injectability coefficient, pushing force and injection pressure. Injectability of calcium phosphate cement were promoted by increasing liquid/solid ratio, modulating the component of solid or liquid phase, and adding various additives.


CONCLUSIONS
Promoting the injectability of calcium phosphate cement is the clinical requirement.
