[Radionuclide studies on healing in closed transverse fractures of the long tubular bones].

A total of 86 patients were examined by 99mTc-pyrophosphate in the course of therapy using the transosseous synthesis method. An elevated accumulation of the radiopharmaceutical was observed since the first day following a trauma. Maximum enhancement of metabolic processes in the absence of fragment displacement was noted on the 8th week and in the lack of displacement on the 9th-10th week. Then the intensity of bone formation got weaker. It was found appropriate that G. A. Ilizarov's apparatus should be removed exactly at that time. The content of mineral components in the regenerate was over 60% which demonstrated the bone ability to stand physiological loads.
