Abstract Purpose Evaluate the utility of intraoperative traction (IOT) during posterior spinal fusion (PSF) in a matched cohort at a high-volume neuromuscular scoliosis (NMS) center. Methods A nested case–control study was performed on a single-center retrospective database of NMS patients. Those diagnosed with cerebral palsy were pair-matched by age (± 1 year), preoperative curve magnitude (± 10°), preoperative traction curve magnitude (± 10°), and flexibility index (± 5%). Paired t tests or Wi
