Abstract
Objective. Electromyographic assessment of neurological deficiency in lower limbs of patients with dysplastic scoliosis before the treatment and at different stages of surgical correction of the spine.
Material and Methods. A total of 107 patients at the age of 11 to 27 years with dysplastic C- and S-shaped scoliosis of grades III and IV was examined. The methods of general and stimulation electromyography were applied before surgery, intraoperatively, and after surgery.
Results. Preoperative neurological status of patients with grade III–IV scoliosis could be defined more exactly using the suggested version of complex neurophysiological testing of sensorimotor apparatus of the lower limbs. Data of postoperative electroneuromyographic analysis of conduction integrative functions of the spinal cord evidence that spine deformity correction in patients with grade III–IV scoliosis by applying an external transpedicular fixation is less invasive but this does not exclude the need for intra- and postoperational neurophysiological monitoring.
Conclusion. Surgical intervention and prolonged correction of the spine axis result in development and subsequent involution of subclinical forms of sensory and motor deficiency in the lower limbs which are more intense in grade IV scoliosis patients.
