ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of the composite bone material, fibrin glue (FG) combined with beta-tricalcium phosphate (beta-TCP)/monocalcium phosphate, in repairing bone defects and assess the feasibility of using this cement for artificial joint fixation.</p><p><b>METHODS</b>Bone defects were induced in 16 normal adult New Zealand white rabbits at the bilateral femoral lateral condyles where an 8-mm-deep hole (4 mm in diameter) was drilled on each side. The composite FG/calcium phosphate cement (CPC) (solution power volume ratio of 0.31) was injected on one side of the bone defects (experimental group) and pressurized for 10 minutes, and CPC was injected on the other side (control). The rabbits were sacrificed at 2, 4, 8 or 12 weeks after the operation for gross observation and biomechanical tests.</p><p><b>RESULT</b>The composite material FG/CPC was more effective than CPC for bone defect repair, and biomechanical tests revealed significant differences between them (P<0.05). The shear stress of the artificial bone cement in the FG/CPC group was stronger than that in CPC group.</p><p><b>CONCLUSION</b>The FG/CPC composite possesses good biocompatibility and osteoconductivity and may serve as an ideal material for repairing bone defects.</p>
