Evaluation of the role of ventral interventions in the surgery of idiopathic scoliosis in patients with active bone growth

BACKGROUND: Today, the question of the tactics of surgical treatment of patients with idiopathic scoliosis during active bone growth, namely, the need for ventral interventions due to the emergence of modern dorsal instruments, remains open. AIM: This study aims to evaluate the role of ventral interventions in the surgical treatment of patients with progressive idiopathic scoliosis Lenke type 1, 2, 3 during the period of active bone growth. MATERIALS AND METHODS: The long-term results of operational correction 352 patients with thoracic idiopathic scoliosis aged from 10 to 14 years old operated in Novosibirsk Research Institute of Traumatology and Orthopedics n.a. Ya.L. Tsivyan from 1998 to 2018 using various methods and different instrumentation types. RESULTS: Among patients (352 people) aged 10 to 14 years with idiopathic thoracic scoliosis (Lenke type 1, 2, 3), statistically significant postoperative progression was observed in patients who underwent surgical deformity correction using laminar (hook) fixation. At the same time, additional ventral stage conduction could not prevent deformity progression in the postoperative period. In those groups where hybrid fixation was used combined with the ventral stage and total transpedicular fixation, no significant progression was observed in the postoperative period. CONCLUSION: Modern dorsal systems for transpedicular fixation narrow the indications for using additional mobilizing and stabilizing ventral interventions in the surgical treatment of progressive idiopathic scoliosis in patients with active bone growth. Total transpedicular fixation provides excellent main curve and anti-curvature arch correction in the absence of scoliotic deformity progression in the postoperative long-term follow-up.
