The reaction of the body during the implementation of the spokes of transosseous fixation devices in biologically active zones

Connection between complications (local and general) and lesions as well as prolonged irritation of biologically active zones by pins during external intraosseous osteosynthesis was detected and proved. Preventive measures of those complications were elaborated. Those preventive measures included insertion of pins beyond active zones after preliminary marking of active points (or canal). Observance of those rules provided decrease of the complication rate by 1.6 times when hinge-distraction devices were used and decrease by 1.8 times in application of reposition- fixation devices. When complications occurred the most radical treatment was either removal of pin that injured the biologically active point or reinsertion of that pin beyond the zone. Analysis of 770 cases (320 patients with hinge-distraction devices and 450 patients with reposition- fixation devices) was taken as a principle of that work.
