[Dynamics of the blood supply in the leg soft tissue in the course of experimental defect filling].

Hemodynamics in the leg soft tissues during bone regeneration in the diaphyseal defects separated from surrounding paraosseous tissues, was studied experimentally using 10 adult mongrel dogs. It has been established, that circulation changes occur both in the operated limb and in the contralateral limb. They are most obvious in the operated leg and have a phase character corresponding to posttraumatic period. Restoration of blood flow parameters starts just from the 28th day of the experiment, the parameters become completely stabilized by the end of the experiment (90 days). Bone regeneration in tibial defects is accompanied by circulation increase in the respective limb segment.
