ASSESSMENT OF THE FUNCTIONAL STATE OF THE EXTREMITY IN PATIENTS WITH CLOSED FRACTURES OF SHIN BONES DURING THE TREATMENT BY ILIZAROV’S METHOD

Abstract

Objective - an assessment of influence an oxygen mode in tissues and rigidity of bone fragment fixation on blood supply in bone regenerate during the treatment by ILizarov's method of patients of different age with closed fractures of shin bones. Blood flow velocity in a region of closed tibia fracture was investigated using high-frequency Doppler ultrasound in the treatment of patients by Ilizarov (193 cases). The rate of blood flow in the area of fracture was increased in first weeks after injury and normalized with the increase of bone regenerate stiffness. In patients aged over 40 years in the tissues of the damaged shin a greater decrease in oxygen tension and a relatively greater increase in blood flow velocity in the zone of bone regenerate were noted.
