Purpose Prolonged surgical duration in severe adolescent idiopathic scoliosis (AIS) patients is associated with increased blood loss and perioperative complications. The aim of this study was to compare the duration of each stage of posterior spinal fusion (PSF) in severe AIS (Cobb angle >= 90(degrees)) with non-severe AIS patients. This analysis will identify the most time-consuming stage of PSF and help surgeons formulate strategies to shorten operative time. Methods Retrospective study whereby 90 AIS patients (Lenke type 2, 3, 4, and 6) who underwent PSF from 2019 to 2023 were recruited. Twenty-five severe AIS patients were categorized in Gp1 and 65 non-severe AIS patients in Gp2. Propensity score matching (PSM) with one-to-one with nearest neighbor matching (match tolerance 0.05) was performed. Outcomes measured via operation duration of each stage of surgery, blood loss, number of screws, fusion levels and screw density. Results Twenty-five patients from each group were matched. Total operative time was significantly higher in Gp1 (168.2 +/- 30.8 vs. 133.3 +/- 24.0 min, p < 0.001). The lengthiest stage was screw insertion which took 58.5 +/- 13.4 min in Gp1 and 44.7 +/- 13.7 min in Gp2 (p = 0.001). Screw insertion contributed 39.5% of the overall increased surgical duration in Gp1. Intraoperative blood loss (1022.2 +/- 412.5 vs. 714.2 +/- 206.7 mL, p = 0.002), number of screws (17.1 +/- 1.5 vs. 15.5 +/- 1.1, p < 0.001) and fusion level (13.1 +/- 0.9 vs. 12.5 +/- 1.0, p = 0.026) were significantly higher in Gp1. Conclusion Screw insertion was the most time-consuming stage of PSF and was significantly longer in severe AIS. Adjunct technologies such as CT-guided navigation and robotic-assisted navigation should be considered to reduce screw insertion time in severe AIS.
