Scoliosis is a 3-dimensional, structural deformity of the spine. Idiopathic scoliosis is the most common type and it constitutes 75-80% of all scoliosis. Surgical methods are the most effective way to correct the deformity in patients who cannot achieve adequate improvement with supportive therapy. Adolescent idiopathic scoliosis surgeries are among the most invasive surgeries performed on children and adolescents. Large surgical incision and massive tissue damage cause severe postoperative pain. In this study, we aim to compare posterior instrumentation (PE) and vertebral body tethering (VBT) surgeries performed in adolescent idiopathic scoliosis patients in terms of anesthetic management and postoperative pain.
