title: [Vascularization of the tibia during compensation for a diaphyseal defect by lengthening one of the fragments using Ilizarov's method].
abstract: In the experiment performed on 67 dogs (2 series) by means of the x-ray vasographic and morphological methods changes in all the links of the bone vascular system have been studied during the compensatory course of the diaphyseal defect (20% of the shin length), taking into account certain peculiarities of local blood supply of the nonfree bone fragment being dislocated. When its medullary blood stream is switched off, it is accompanied with certain disturbances in blood circulation and in blood circulation and in decreasing of its participation in formation of the vascular network of the distractive regenerate. The circulatory disturbances are compensated at the expense of reconstruction of the periosteal vascular network, which ensures restoration of the magistral type of the bone blood supply. Preservation of the medullary blood stream ensures an adequate blood supply of the fragment and a high regenerative ability of the blood vessels.
