Herein are presented clinical examples of segmental lordosis according to PI. In patients with low (A) and average (B) PI, the main part of the lordosis occurs within the distal vertebrae, whereas in patients with high PI (C), almost 40% of the total lordosis is located within the proximal vertebrae. Of note, the distal lordosis was almost constant in these three patients, independent of the PI value.
