Background. Currently, there are many studies on the evaluation of the results of surgical intervention and the comparative analysis of various surgical techniques for treating children with congenital spinal deformities. However, there is no consensus regarding the choice of surgical access to the abnormal vertebra that considers the duration of surgery, the volume of intraoperative blood loss, the degree of correction achieved during the intervention, the length of metal fixation, and the preservation of the result in the long-term observation period. Aim. The goal is to identify the advantages and disadvantages of the dorsal and combined approaches to the surgical treatment of preschool children with congenital deformities of the thoracic and lumbar spine against the background of an isolated violation of the vertebral formation. Materials and methods. A retrospective analysis of 56 patients under the age of five with congenital spinal deformities and a history of an isolated hemivertebra in the thoracic and lumbar regions who underwent one-stage hemivertebral extrusion from a dorsal approach (1st group: n = 30) or from a combined approach (2nd group: n = 26) was conducted. Results. All patients showed improvement in the sagittal and frontal profiles of the spine. However, during separation in the first group of patients, a progression of the kyphotic component of the deformity in the lumbar spine from 19 to 8 was noted, while the correction value of the curvature of the scoliotic component remained stable. Intraoperative blood loss in the first group of patients was less (234 mL) compared with that in the second group (319 mL), while the duration of surgery was longer (310 min and 185 min, respectively). On average, in the first group, a longer metal structure was used to correct the spinal deformity compared with the second group. Conclusions. The correction of the patients congenital spinal deformities with a single hemivertebra from a combined access approach allows a complete correction of the congenital curvature, the fixation of a smaller number of vertebrae, and the maintenance of a stable result in the long-term observation period compared with the dorsal approach. Isolated dorsal access to the hemivertebral body is characterized by less intraoperative blood loss compared with the combined approach, although the length of surgical intervention is increased.

Background. One of the most common vertebral malformations that lead to the occurrence and progression of congenital scoliosis is disorders of vertebral formation. Most specialists adhere to the active tactics of surgical correction of spinal deformity in early childhood. The aim. To evaluate the variants and causes of the transpedicular spinal system destabilization, which is not related to the violation of its integrity, in the surgical treatment of children with congenital spinal deformities. Materials and methods. The case histories of 286 children under the age of 6 years undergoing surgical treatment in H. Turner National Medical Research Center for Сhildrens Orthopedics and Trauma Surgery between 2014 and 2019 were analyzed. Depending on the outcome of the surgical treatment, the patients were divided into groups: the main group (n = 7) included those with spinal system destabilization and the control group (n = 12) consisted of those without spinal system destabilization. During the study, the sizes of the bases of the arcs adjacent to the abnormal vertebra, the magnitude of the scoliotic and kyphotic components of the deformation, and the correct position of the supporting elements of the spinal system on the Gertzbein scale were determined. Results. Patients of the studied groups were identified according to their age and the magnitude of scoliotic and kyphotic components of spinal deformity. The average diameter of the arc base in the studied groups varied (p 0.05). In all patients, the complete correction of the congenital curvature of the spine was achieved after surgery. In the long-term postoperative period in patients of the study group after radiation analysis, the malposition of supporting elements relative to the base of the vertebral arch and a loss of correction of spinal deformity by an average of 25 were revealed, which required the repeated surgery in order to restore the stability of the spinal system and to correct deformation. Conclusions. The reasons for the spinal system destabilization during the correction of the spinal congenital deformations are the peculiarities of vertebral anatomical-anthropometric parameters in the curvature zone, as well as tactical aspects during surgery. The main reason for the spinal system destabilization without violating its integrity is the small size of bases of adjacent vertebral arches relative to the abnormal one. The small size of the bases of the vertebral arches and the significant amount of necessary correction of congenital spinal deformity necessitate the installation of a longer spinal system in order to restore physiological profiles in the curvature zone.

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.

BACKGROUND: Despite a detailed study of the natural development of congenital spinal deformity in isolated semivertebrae and methods of surgical correction of this pathology, some issues remain unclear. The age at which surgical correction of congenital spinal deformity should be performed is a debated issue among specialists. AIM: To conduct a comparative analysis of the effectiveness of correction of spinal deformity in children with congenital kyphoscoliosis with isolated semivertebrae of preschool and primary school-age children. MATERIALS AND METHODS: We included 26 patients aged 21 months to 69 months (10 girls and 16 boys) with congenital kyphoscoliosis caused by an isolated semivertebra. The patients underwent partial or complete resection of the semivertebral disk with adjacent intervertebral disks from dorsal or combined access, correction and stabilization of congenital spinal deformity with a posterior multisupport metal structure. Participants were sectioned into two age groups: the first group children under 4 years (14 children), the second group children 6 years and older (12 children). RESULTS: Metal fixation during surgical treatment in children of primary school age as well as in preschool children was carried out in the majority of cases polysegmentarily. Regarding the choice of surgical treatment access, dorsal surgical access was more often preferred in the second group of patients. The duration of surgical intervention and volume of blood loss between different age groups were similar with dorsal and combined access. In the group of preschool children, destabilization of the metal structure was noted in the early postoperative period when performing control radiographs after surgical treatment in three cases. In the second group, spinal deformity of dysplastic genesis after surgical treatment was detected in three cases. CONCLUSIONS: The effectiveness of surgical treatment of congenital deformity is significantly higher in younger children compared to that in school-age patients.

BACKGROUND: Treatment of children with congenital deformity with unsegmented rod and rib synostosis is an important and topical problem to date. Topical publications present the results of surgical correction efficacy and analysis of treatment complications. The extremely important aspect of treatment efficacy assessment regarding changes in the function of external respiration is still topical. AIM: This study aimed to analyze the treatment results of children with congenital scoliosis and unilateral segmentation disorder of the lateral surfaces of the vertebral bodies and rib synostosis. MATERIALS AND METHODS: This is a retrospective monocenter cohort study of the treatment outcomes of 30 patients aged 114 years. In the preoperative period, external respiration was evaluated by pulse oscillometry, multi-slice computed tomography, digital X-ray imaging of the craniopelvis in two projections. All patients underwent expanding thoracoplasty with osteotomy of the rib synostosis and fixation with a rib-costal or rib-vertebral distractor. Control studies were performed every 6 months after the surgical intervention. The average follow-up period was 2 years. Nonparametric analysis was applied to estimate the obtained data. RESULTS: The median (Me) age at the start of treatment was 6 years (interquartile range, 4.25; IQR hereafter). The Me scoliosis before treatment was 74 (IQR, 22.75). The Me scoliosis correction after the first stage of treatment was 16 (IQR, 11) and the second correction achieved 6 (IQR, 13). The Me kyphosis was 15 (IQR, 32), the first intervention improved kyphosis by 4 (IQR, 16), and the second by 6 (IQR, 11). Complications were represented by the destabilization of the metal construct in six cases, and trophic disorders of soft tissues were noted in four. The assessment of external respiratory function using IOM demonstrates reliable improvement of resistive component, reactive component, and frequency dependence of the resistive component (p 0,01). CONCLUSIONS: The assessment of the external respiratory function in young children and analysis of reference values may allow their use as absolute indications for surgical treatment in children with congenital scoliosis with unsegmented bar and rib synostosis.
