This retrospective study analyzed 52 patients who underwent scoliosis surgery between 2014 and 2023
in private hospitals in the Central-West region of Brazil. The objective was to evaluate the degree
of curvature correction, using the Cobb method, and postoperative complications. The sample was
predominantly female (86.6%), with a mean age of 16 years. The majority of patients (92.3%) were
diagnosed with idiopathic scoliosis (IS), with 57.7% presenting thoracic curves and 34.6% presenting
lumbar curves, according to the Lenke classification. The average preoperative Cobb angle was 55°, with
a postoperative average correction of 74%, reflecting the effectiveness of spinal arthrodesis techniques
with pedicle screws. There were no neurological complications, but significant bleeding was observed
in three cases, and revision surgery was required in two patients due to postural decompensation. These
results are consistent with recent advances in scoliosis surgery, including the use of intraoperative
neurophysiological monitoring and more sophisticated instrumentation techniques, such as the CotrelDubousset system. Although highly effective and safe, complications such as blood loss and postural
decompensation can occur, requiring continuous monitoring and corrective interventions. This study
reaffirms the importance of modern surgical approaches and the high demand for treatment in the region.
