Analysis of the Effectiveness of Guide Templates for the Placement of Pedicle Screws in the Surgical Treatment of Children with Congenital Scoliosis

Objective: to conduct a comparative analysis of the correct position of transpedicular screws installed in the vertebral bodies in young and preschool children with congenital kyphoscoliosis of the thoracolumbar junction and lumbar spine against the background of abnormal formation of the vertebrae by the "free hand" method in vivo and in plastic models of vertebrae using templates -Directors in vitro. Methods. A comparative analysis of the correctness of the position of transpedicular screws installed in the vertebral bodies in young and preschool children with congenital kyphoscoliosis of the thoracolumbar junction and lumbar spine against the background of a violation of the formation of the vertebrae by the "free hand" method in vivo and in plastic models of the vertebrae using guide templates in vitro. Results. The number of correctly inserted transpedicular screws in plastic models of the vertebrae of children with congenital deformities of the thoracolumbar and lumbar spine using guide templates was significantly higher than the number of correctly installed screws using the free hand method (96.3% versus 80.8%, p = 0.011). Conclusion. The obtained results of in vitro guide templates application showed high accuracy and correctness of pedicle screw placement, which gives prospects for the use of this type of navigation in clinical practice in young children with congenital scoliosis.
