A systematic search of articles about one-stage posterior spinal fusion for severe AIS was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data about population, pre-and postoperative radiographical data, surgical procedure details, and complications were extracted. Meta-analyses were performed when possible. Fourteen studies (640 patients) were included. The mean Cobb angle of the major curve varied from 80.0 ± 7.3 to 110.8 ± 12.1. The meta analysis showed a comprehensive coronal correction rate of the major curve of 58.6%, a comprehensive operative time of 274.5 min, and a comprehensive estimated intraoperative blood loss of 866.5 mL (95% confidence interval: 659.3–1073.6, I2 ≈ 0%). A total of 48 complications (5.4%) were reported. Overall, the meta-analysis showed a major complication rate of 4%. In seven cases, revision surgery was needed. Posterior-only approach is effective enough to correct severe curves and can spare the patient possible adverse events due to anterior approach. However,...
