Objective. To perform a comparative analysis of the results of anterior versus posterior spinal fusion in patients with idiopathic scoliosis. Material and Methods. A total of 30 patients with idiopathic scoliosis were operated on. Group I included patients who underwent anterior spinal fusion, and Group II - those who underwent posterior spinal fusion. Cobb angles of the primary curve and countercurve, thoracic kyphosis and lumbar lordosis before surgery and 2 years after treatment, average number of fixed vertebrae, intraoperative blood loss, surgery duration, and duration of hospital stay were assessed. Results. The study revealed no statistically significant differences between groups in the pre- and postoperative Cobb angle values in both the frontal and sagittal planes. Both methods equally allowed to carry out the correction of all components of scoliotic curvature. Statistically significant difference in thoracic kyphosis and lumbar lordosis angles is caused by anatomic features of sagittal contour in two groups of patients. At the same time a normal sagittal contour of the spine was disturbed neither by anterior no by posterior fusion, and postoperative parameters were within permissible limits. Conclusion. Application of anterior corrective spinal fusion methods reduces intraoperative blood loss, length of spine fixation, and duration of hospital stay, and improves the patient’s quality of life. Hir.
