Research Article: The outcome of surgical correction of severe scoliotic spinal deformities on sagittal balance in adolescents
Abstract:
In recent years, the concept of sagittal trunk balance in patients with spinal deformity has been significantly developed. The main disorders in the sagittal plane are decreased thoracic kyphosis, compensatory decrease in lumbar and cervical lordosis, and negative sagittal balance. However, these issues remain insufficiently studied in the literature.
To show, analyze and clarify the effect of surgical correction of spinal deformity in adolescents with severe forms of idiopathic thoracic scoliosis on the parameters of sagittal balance, outcomes and efficiency of surgical treatment for sagittal balance.
Patients with idiopathic thoracic scoliosis (Lenke types 1–3) aged 12–17 years underwent discapophysectomy at the apex of the main curve, intraoperative halo traction, and posterior multi-support metal fusion with stabilization in one session. All operations were performed at the G.I. Turner National Research Medical Center between 2017 and 2025.
There were 5 boys (13.2%), 33 girls (86.8%) with average age of the patients was 15.0?±?1.3 years. Main thoracic curves ranged from 80° to 140° according to Cobb (average—102.8°). A positive correlation of moderate strength was revealed between the values of TK and SVA (Spearman correlation coefficient 0.33, p <?0.05), a negative correlation of moderate strength between the values of TK and SSA (Spearman correlation coefficient ?0.31, p <?0.05).
Discapophysectomy at the apex of the main curvature, intraoperative halo traction, and correction of deformity with a posterior multi-support metal spinal fusion and stabilization in one surgical session contributed to achieving normal global and regional parameters of sagittal balance in adolescent patients with severe forms of idiopathic thoracic scoliosis.
