[Animal experimental scintigraphic observations of the course of secondary fracture healing without and with ultrasound stimulation].
The scintigraphic course observation until the biologic fracture healing took place on the fracture model of the closed lower leg fracture with secondary fracture healing in rabbit. 151 scintigraphic investigations were carried out by means of 99mTc HEDP. The ROI activity quotient increased significantly on the 14th day after the fracture up to the maximum value Q = 6.44. 61 fractures of the lower leg were treated by ultrasound from the 14th to the 28th day after the fracture. These stimulated fractures showed a biologic healing on the 168th day already. The fractures treated without ultrasound could not be proved any more scintigraphically after the 203rd day after the fracture.
