[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.

CONCLUSION

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