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.
Approach:
Study Design: Single-center cohort retrospective study involving 38 patients aged 12–17 years with idiopathic scoliosis who underwent surgical treatment.
Surgical Technique: Patients underwent discapophysectomy at the apex of the main curve, intraoperative halo traction, and posterior multi-support metal fusion with stabilization in one session.
Radiographic Assessment: Panoramic radiographs were taken before and after surgery to analyze parameters of sagittal balance using the Surgimap program.
Key Findings:
The study included 38 patients, with an average age of 15.0 ± 1.3 years. Main thoracic curves ranged from 80° to 140° (average 102.8°).
A moderate positive correlation was found between thoracic kyphosis (TK) and sagittal vertical axis (SVA) with a Spearman coefficient of 0.33 (p < 0.05).
A moderate negative correlation was found between TK and sacral slope angle (SSA) with a Spearman coefficient of -0.31 (p < 0.05).
Interpretation:
Surgical intervention contributed to achieving normal global and regional parameters of sagittal balance in adolescent patients with severe idiopathic thoracic scoliosis.
Limitations:
Study limited to a single center and a small cohort of patients.
Exclusion of patients with congenital spinal pathologies and previous surgeries may limit generalizability.
Conclusion:
Surgical correction improved sagittal balance parameters in adolescents with severe idiopathic thoracic scoliosis.
