Abstract:
Objective To investigate the ability of repairing bone defect with the compound of hydroxyapatite(HA),red bone morrow (RBM), bone morphogenic protein(BMP)and fibrin sealant (FS),and the feasibility with the compounds as bone substitute material. Methods The animal models of bilateral radius bone defect were created by surgery in the New Zealand white rabbits, and were treated with the compound of HA, RBM, BMP and FS, by autograft and no implant as control.The effect were observed by gross, histopathological and X-ray examinations, and were determined by biomechanics at 2,4,8 and 12 weeks after operation. Results By gross, histopathological and X-ray examinations, the effect indicated that the bone defect were perfectly repaired with autograft and the compound of HA, RBM, BMP and FS at 12 weeks, but not with the no implant group. The effect of biomechanics had no statistically significant difference between the autograft and the compound of HA, RBM, BMP and FS. Conclusion The compound of HA, RBM, BMP and FS possesses much high bone inductive potentialities and the ability of rebuilding bone defect and can serve as an autograft substitute material.
