[Radionuclide studies of reparative osteogenesis during modeling the shape of the leg]

The time course of metabolic processes in the osseous tissue and the capillary blood circulation in the forming osseous regenerate and the bone as a whole were studied in 16 patients using pyrophosphate and DTPA. The results of radiometry made it possible to give a quantitative evaluation of regeneration intensity: during intensive osteogenesis the accumulation of labeled pyrophosphate increased up to 720%, and the capillary blood circulation speeded up to 380%. Before the completion of osteogenesis the drug accumulation decreased considerably up to 250%.
