摘　　要：The purpose of this study was to find a kind of new artificial bone for anterior spinal fusion.ZrO 2 stabilized by Y 2O 3(Y-PSZ),porous hydroxyapatite(HA) and bone morphogenetic protein (BMP) were used to make artificial compound bone (Y 2O 3) ZrO 2-HA/BMP(Z-H/BMP),whose function was tested,microstructure and mineralogic composition constitution were analysised by SEM and XRD,and the corresponding animal tests were porformed.Osteogenesis of the material was observed by eyes,histology and SEM.Experimental results show that the component and ossific activity of Z-H/BMP were satisfactory.The purpose of this study was to find a kind of new artificial bone for anterior spinal fusion.ZrO 2 stabilized by Y 2O 3(Y-PSZ),porous hydroxyapatite(HA) and bone morphogenetic protein (BMP) were used to make artificial compound bone (Y 2O 3) ZrO 2-HA/BMP(Z-H/BMP),whose function was tested,microstructure and mineralogic composition constitution were analysised by SEM and XRD,and the corresponding animal tests were porformed.Osteogenesis of the material was observed by eyes,histology and SEM.Experimental results show that the component and ossific activity of Z-H/BMP were satisfactory.
