Figure 2 Lumbar lordosis (LL) is formed by 2 perpendicular tangent lines drawn through the superior endplate of L1 and the inferior endplate of L5. Pelvic tilt (PT) is formed by drawing a straight line through the middle of the superior endplate of S1 and connecting the centers of the bilateral femoral heads, and the angle formed by the straight line and the long axis of the body is shown. Sacral slope (SS) is formed by the tangent line to the superior endplate of S1 and the horizontal line. Pelvic incidence (PI) is formed by drawing a line from the center of the S1 endplate to the centers of the bilateral femoral heads. The angle formed by the vertical line to the superior endplate of S1 is shown.
