[Hemodynamics in soft tissues after upper third of the leg lengthening by Ilizarov osteosynthesis technique]

An experimental study has been performed. The leg was lengthened in 12 adult mongrel dogs by transosseous distraction osteosynthesis in the zone of upper third of the leg bone shaft by 14-18% of the segment length using the rate of 1.0 mm for 4 times. The formation of mechanically strong shaft part occurred after 35 days after device fixation. Under created conditions the unidirectional cyclic changes of blood circulation and morphofunctional state occurred in soft tissue segment, that were more marked in the extensor muscle group. Implementation of preventive-and-treatment measures directed to improvement of vascular elastotonic properties allowed to decrease the degree of disordering hemodynamics of the lengthened limb. This will have a positive effect on the final clinical outcome.
