Abstract
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 Сhildren’s 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.
