In adult spinal deformity (ASD) surgery, 3-column osteotomies (3COs) are often performed to correct severe and rigid spinal deformities. Despite the increased risk of neurologic deficits, to our knowledge, this is the first study to compare and characterize sensory and motor complications between ASD patients with and without 3COs. To characterize differences in neurologic complications and outcomes associated with 3CO in ASD surgery. Multicenter prospective cohort study. ASD patients undergoing surgery with and without 3CO. Patient demographics, surgical characteristics, and postoperative complications of ASD patients undergoing surgery. A total of 553 ASD patients who underwent surgery were examined. Patients with and without 3COs were compared with respect to patient demographics, surgical characteristics, and neurologic complications using chi-square or student's t-test. Lower extremity motor strength (LEMS) scores were also compared at baseline (BL), 6-week, and 1-year postop. Among 553 ASD patients, 23.50% (130/553) had 3CO performed, with a greater rate of males having 3CO performed (41.54% vs 26.48%; p=0.001). 3CO patients were more likely to be revision patients (67.7% vs 35.0%; p
