Experimental staged study of blood flow in crus lengthening by Ilizarov was performed in 23 adult dogs. The results of electromagnetic flowmetry showed that distraction of crus tissues contributed to the decrease of the rate by volume in the femoral artery but the formation of the distraction bone regenerate - to its increase. Lengthening of the crus was accompanied by the accelerated transit of blood from the arterial bed to the venous one which was maintained by the vascular network of bone regenerate. Basing on the changes in pressure gradient it has been concluded that stimulation of blood circulation in the extremity was dependent on the responce of cardio-vascular system as a whole.
