Although three-column osteotomies (3-CO) provide powerful correction, they are associated with prolonged operative time, increased blood loss, and high neurological risk. This study aimed to compare the radiographic correction, surgical parameters, and complication profiles between staged halo-pelvic traction combined with posterior spinal fusion (HPT+PSF) and one-stage posterior spinal fusion (PSF) in patients with severe rigid spine deformity requiring 3-CO.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n This retrospective cohort study included 110 patients (mean age, 25.7 \u00b1 8.5 years) with severe rigid deformity (Cobb angle or maximal kyphosis >90\u00b0, flexibility <30%) who underwent either staged HPT+PSF (n = 60) or single-stage PSF (n = 50) between 2016 and 2023. Radiographic parameters, including the main curve Cobb angle and maximal kyphosis (MK), were measured preoperatively, post-traction, postoperatively, and at the latest follow-up. Operative time (ORT), estimated blood loss (EBL), osteotomy grade, intraoperative neuromonitoring (IONM) alerts, and complications were compared between groups. Pulmonary function tests (PFTs) were evaluated longitudinally.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Following traction, the main curve Cobb angle and MK in the HPT+PSF group improved from 132.4\u00b0 \u00b1 23.3\u00b0 to 65.1\u00b0 \u00b1 20.7\u00b0 and from 122.3\u00b0 \u00b1 29.7\u00b0 to 53.3\u00b0 \u00b1 24.1\u00b0, respectively. At the last follow-up, the correction rate of the main curve and MK were significantly higher in the HPT+PSF group than in the PSF group (62.9% vs 55.2%,\n P<\/jats:italic>\n = 0.004; 67.7% vs 54.5%,\n P<\/jats:italic>\n < 0.001). The HPT+PSF group demonstrated significantly reduced ORT (298.3 \u00b1 64.7 vs 361.9 \u00b1 76.3\u00a0min,\n P<\/jats:italic>\n < 0.001) and EBL (490.5 \u00b1 183.3 vs 1010.6 \u00b1 252.1\u00a0mL,\n P<\/jats:italic>\n < 0.001). The rate of IONM alerts (3.3% vs 20.0%,\n P<\/jats:italic>\n = 0.005) and neurological deficits (3.3% vs 14.0%,\n P<\/jats:italic>\n = 0.042) were markedly lower in the HPT+PSF group. Although traction-related complications occurred in 16.7% of patients, all were transient and resolved after adjustment of HPT devices.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Staged HPT followed by PSF provides a safe and effective strategy for the management of severe rigid spine deformities. In terms of radiographic correction and perioperative safety profile, this staged approach demonstrated significant advantages over one-stage 3-CO, notably reducing operative time, blood loss, and neurological risks. Preoperative traction effectively decreases deformity stiffness and magnitude, facilitating safer and less invasive surgical correction.<\/jats:p>\n
