  1. GK global kyphosis, LK local kyphosis, SVA sagittal vertical axis
  2. Two-way repeated ANOVA with post hoc analysis was used to compare the preoperative, postoperative and the latest follow-up radiographic data. There were significant differences between preoperative and postoperative, postoperative and the latest follow-up in radiographic data for P value less than 0.05 (* between preoperative and postoperative, † between preoperative and the latest follow-up). *1P = 0.019, *2P = 0.008, *3P = 0.006, *4P = 0.000, *5P = 0.000, †1P = 0.026, †2P = 0.017, †3P = 0.012, †4P = 0.000, †5P = 0.000,
