FORMALIZING THE RESULTS OF INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING OF THE MOTOR PATHWAYS INTO THE SPINAL CORD DURING THE SURGICAL CORRECTION OF SPINAL DEFORMITIES

OBJECTIVE. systematization of the electrophysiological phenomena observed during the intraoperative neuro-monitoring with subsequent development of the grading system for results of neuro-physiological testing of pyramidal tract, convenient for surgeon. MATERIAL AND METHODS. 288 patients, at the age of 1–27, under intraoperative neurophysiological monitoring underwent instrumental correction of deformity of the thoracic/thoracolumbar spine. RESULTS. We evaluated in points the changes of motor evoked potentials, observed during the surgical intervention. It was observed that the frequency of changes of their parameters, indicating the danger of iatrogenic lesions, depended on the age of the patient and did not exceed 10 % of the total amount of observations. CONCLUSION. Intraoperative neurophysiological monitoring allows the surgeon and anesthesiologist to correct their actions in a timely fashion; and it minimizes the danger of iatrogenic neurological disorders.
