In 6-7-month-old puppies of mongrel dogs under anesthesia by means of G. A. Ilizarov apparatus double epiphysiolysis of the tibia has been performed. The activity of metabolic processes, the state of blood and lymphatic circulation have been studied in the shin at its lengthening by radioisotopic, angiographic and histological methods. Beginning from the first postoperative days, an essential increase of metabolic processes is observed in the osseous tissue, in the blood circulation at the areas of distraction and in the shin as a whole. Blood supply of the regenerates, when the magistral and intraosseous blood stream is remained intact, is performed via the nutritional, metaphysial and epiphyseal arteries. The preservation of the magistral blood stream ensures formation of a normal blood bed in the red bone marrow (arterioles, closed system of the sinuses). |
