| At 3 months after surgery, 28 pairs of radiographic data were available to analysis. At 6 months after surgery, 28 pairs of radiographic data were available to analyze. At 12 months after surgery, 24 pairs of radiographic data were available for analysis. T2-T5 – angle between upper endplate of T2 and lower endplate of T5; T5-T12 – angle between upper endplate of T5 and lower endplate of T12; T10-L2 – angle between upper endplate of T10 and lower endplate of L2; T12-S1 – angle between upper endplate of T12 and upper endplate of S1; SS – sacral slope; PT – pelvic tilt; PI – pelvic incidence; SVA – sagittal vertical axis; OVF – osteoporotic compression vertebra fractures; Pfirrmann – Pfirrmann index of the adjacent segment disc | |||
