The purpose of this study was to find a kind of new artificial bone for anterior spinal fusion.ZrO2 stabilized by Y2O3 ( Y- PSZ), porous hydroxyapatite ( HA ) and bone morphogenetic protein (BMP) were used to make artificial compound bone ( Y2O3 ) ZrO2 -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.
