Advantages of using template guides in children for the correction of congenital spinal deformities and thoracic anomalies

BACKGROUND: In children, progressive congenital deformities of the thoracic spine combined with thoracic anomalies require surgical intervention to correct the curvature and prevent further progression during the child’s growth. Surgical correction of congenital deformity caused by segmentation disorders of the lateral surfaces of the vertebral bodies with unilateral rib synostosis aims at full correction of the existing curvature using the transpedicular spinal system and is an effective and reliable treatment option for these patients. However, this technology requires precise and correct installation of the supporting elements of the metal structure to exclude possible irreversible complications. A solution is the use of template guides in the installation of the support elements of the spinal metal structure.

AIM: This study aimed to conduct a comparative analysis of the results of using template guides for the placement of transpedicular screws with the free-hand method in children during surgical correction of congenital spinal deformities combined with thoracic anomalies.

MATERIALS AND METHODS: The results of surgical treatment of 20 patients, aged 3–9 years, were analyzed retrospectively to compare the time and accuracy of spinal metal support element placement with and without the use of template guides. The data collected included demographic information, time of bone canal formation, accuracy of spinal transpedicular screw placement, and various complications.

RESULTS: Compared with the free-hand method, the use of template guides in the surgical correction of congenital spinal deformities combined with thoracic anomalies in children reduces the time of bone canal formation and increases the accuracy of metal screw placement. These results confirm the efficacy and safety of using template guides during spinal surgery in children with these congenital malformations.

CONCLUSIONS: The use of template guides is an effective and reliable method of inserting transpedicular metal screws in the correction of congenital spinal deformities combined with thoracic anomalies in children, which increases the accuracy of implantation of support elements and reduces the surgical time. These results confirm the necessity of using template guides in the correction of congenital spinal deformities in children.
