Comparison of Open Surgery Versus Minimally Invasive Surgery in Nonsevere Adult Degenerative Scoliosis

In mild to moderate ADS, we found that the advantages of open surgery include greater improvement in lumbar lordosis and pelvic tilt angle and shorter operative time. The advantages of minimally invasive surgery are less intraoperative blood loss, shorter hospital stay, and fewer serious postoperative complications. There is no significant difference between the 2 surgical methods in terms of Cobb angle, clinical pain, and sagittal vertical axis improvement.
