Abstract：
 The invention relates to compound porous calcium orthophosphate skeleton cement. Wherein, said cement is formed by calcium orthophosphate skeleton cement powder, 3-hydroxy butanoic acid-CO-3-hydroxy pentanoic acid polymer microball, and solidify liquid. And the production comprises: preparing orthophosphate skeleton cement solid powder; preparing analogue humor; mixing the PHVV microball radiated by Co60 gama-ray; washing, drying and emerging it in the analogue humor, to be washed and dried; then mixing the PHBV microball and solid powder, to be added with solidify liquid to obtain the product. The invention has high strength, quick degradation and controllable degradation speed. And it can be used to repair skeleton hurt and used as skeleton support.
