Calcium phosphate cement (CPC) has been widely used as bone fillers because of its excellent bioactivity and biocompatibility. Meanwhile, CPC is also an attractive candidate for the incorporation of drug or microspheres, because the preparing procedure avoids sintering and heating release. This paper summarizes the clinical applications of microspheres incorporated in CPC from the aspects of sustained drug release, accelerated degradation, porous structure and improved mechanical properties. The paper is aimed to analyze the methods and principles of microspheres loaded CPC, and so as to lay a foundation for the further research of improving and manufacturing the CPC with ideal properties.
