[Relation of the mechanical properties of callus tissue and its roentgenologic picture during osteotomy in radiation sickness].
The author investigates the relations between the toughness, firmness and elastic module of callus tissue and its X-ray picture in radiation sickness. On the example healing of experimental osteotomy in rabbits he provides evidence that the X-ray picture of the callus does not always correspond to its actual mechanical parameters. He defines an eight-grade classification for evaluation of the X-ray picture of the callus and compares it with three mechanical parameters of the callus from the aspect of restoration of mechanical properties, which is sufficient for common burdening of the injured extremity. In the conclusion he mentions that mechanically adequate healing of the osteotomy is achieved when on the X-ray picture the fracture line is reconstructed and there is a marked periosteal or remodelled callus. In radiation sickness the recovery after osteotomy is adversely influenced, bones with an advanced X-ray picture of the degree of recovery are mechanically less resistant, as compared with the control group.
