From: Increasing pelvic incidence is associated with more global sagittal imbalance in ankylosing spondylitis with thoracolumbar kyphosis: an observational retrospective study of 94 cases

Fig. 2

Lateral X-rays of AS patients showed increasing PI was correlated with more global sagittal imbalance (larger TPA, lower SPA). In Fig.2-a the PI, TPA and SPA were 32.4°, 36.7° and 128.7° respectively. In Fig.2-b the PI, TPA and SPA were 45.9°, 60.4°and 123.3° respectively. In Fig.2-c the PI, TPA and SPA were 56.8°, 66.1° and 99.2° respectively
