The aim of this meta-analysis was to analyze the results of one-stage all-posterior spinal fusion for severe adolescent idiopathic scoliosis (AIS). 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, when choosing this approach for severe AIS, screw density needs to be high and posterior column osteotomies may need to be planned to mobilize the spine and maximize correction.
