Summary
In order to investigate the bovine calcined bone’s ability of repairing segmental bone defect and seek a new artificial bone substitute material, the bovine calcined bone (450°C, 32 h) was implanted into the 10-mm middle radial defect of rabbits with tricalcium phosphate ceramics as the control. By using the methods of histology, radiology and biomechanics their osteogenic ability were measured. It was found that the bovine calcined bone’s ability of repairing bone defect was better than that of tricalcium phosphate ceramics. The histological Nilsson’s scores at 3rd, 5th, 9th week after operation were significantly increased (P < 0.01). At 12th week after operation the bending strength of radius in experimental group was much higher than that of control group and turned normal. It was suggested that bovine calcined bone is an ideal artificial bone substitute material with good ability of repairing segmental bone defect and some degree of mechanical strength.
