RESUMO
Described in the literature properties of osteoplastic material "Cerabone®" have been obtained from studies in the maxilla and cancellous bone. The lack of data on the impact of «Cerabone®¼ on the dynamics of the healing of defects of compact substance of the long bones of the skeleton dictates the need for such studies. Implantation of osteoplastic material «Cerabone ®¼ was performed into the defect of rat femoral shaft followed by computer-tomographic analysis of its healing. Starting from the 30th day until the end of the experiment (120th day) there were found faint signs of rarefaction in the distal part adjacent to the defect of parent bone, with no signs of bone resorption in its proximal part. There was identified an extremely high density of the implantation site «Cerabone®¼, no visible radiographic evidence of resorption of osteoplastic material and ensuring by the latter the stability of volume of the defect in cortical bone at all stages of the experiment.
