[REACTIVITY AND RESISTANCE OF THE SPINAL STRUCTURES WHEN PERFORMING INSTRUMENTAL CORRECTION OF SPINAL DEFORMITIES]
Abstract:
The aim of the study was the electroneuromyographic evaluation of the spinal cord pyramidal structures reactivity and resistance in response to the impact of intraoperative factors associated with the application of technologies instrumental correction of spinal deformities of various etiologies and degrees of severity, realized with the help of submersible transpedicular fixation systems. Before treatment and 4-31 (9.6 ± 0.3) days after surgery using methods of global and stimulation (M-responses) electroneuromyography were examined 135 patients 8-50 (16.4 ± 0.6) years (42 male, 93 female) with spinal deformities of various etiologies and severity. The intrao perative maximum angle correction of the spinal column ranged from 3° to 95° (37.2 ± 1.5°). To assess the reactivity of the spinal cord structures located at the top of the primary arc deformation used integral index - the index of sensorimotor deficit (ISD). The lowest values of ISD and most distinct postoperative negative trends of this indicator were observed in persons with spinal deformities of neuromuscular etiology.
