Figure 1 Cervical parameters on standing lateral X-ray images: (A) Cobb angle: Angle between inferior endplate of C2 and C7. T1S: Angle between a horizontal line and the superior endplate of T1. TIA: Angle between a vertical line and a line connecting the middle of the superior endplate of the T1 to the upper end of the sternum. NT: Angle between a vertical line and a line connecting the middle of the superior endplate of the T1 to the upper end of the sternum. (B) cSVA: Distance between a plumb line dropped from the centroid of C2 to the posterior superior endplate of C7. (C) TPA: Angle between the line from the centroid of T1 vertebrae to the femoral head axis and the line from the femoral head axis to the middle of the S1 superior endplate.
