Spinal osteotomy for children with congenital scoliosis with unilateral unsegmented bar: Preliminary results

Abstract

Introduction. Segmentation disorder of the lateral surfaces of the vertebral bodies leads to the development of progressive deformity of the spine. Surgical interventions in different variants are the only effective way of treatment. This study examines the use of corrective vertebrectomy in patients with congenital scoliosis with impaired segmentation of the lateral surfaces of the vertebral bodies.
 Objective of the study. To evaluate the results of surgical treatment of children with congenital scoliosis with impaired segmentation of the lateral surfaces of vertebral bodies.
 Materials and Methods. A single-center retrospective study on the basis of the Department of Spinal Pathology and Neurosurgery at the Turner Scientific and Research Center for Pediatric Traumatology and Orthopedics. G.I. Turner for the period from 2014 to 2020. Twenty-six patients were included in the study: 14 girls and 12 boys. The age range was 84 to 144 months. All patients underwent surgical intervention in the volume of a one-stage corrective wedge vertebrectomy. Statistical processing was performed by comparing the reliability of differences in distributions using Wilcoxon t-criterion.
 Results and discussion. The median Cobb preoperative scoliotic deformity was 31, interquartile interval (IQR) = 30.5. The median preoperative lordotic deformity was 29 Cobb, IQR = 29.5. The magnitude of correction of the scoliotic component of the deformity was 84%, (median value after intervention: 5 according to Cobb, IQR = 14.5). The magnitude of correction of pathological lordosis of the thoracic spine was 41%, (median value after intervention: 17 according to Cobb, IQR = 14.5). The obtained results were statistically significant (p 0.05).
 Conclusion. Corrective wedge vertebrectomy is an effective method for surgical treatment of children with congenital spinal deformity with impaired segmentation of the lateral surfaces of vertebral bodies. This method of treatment achieves an average of 84% correction of scoliotic deformity and 41% correction of pathological lordosis.
