Bar graph shows the dynamic changes in ligamentum flavum diameter (mean ± standard deviation) during flexion and extension of the cervical spine in group DVI (patients with a disk bulge increase ≥1 mm from flexion to extension), group DVII (patients with a disk bulge increase < 1 mm and > 0 mm from flexion to extension), and group DVIII (patients with a disk bulge increase ≤0 mm from flexion to extension). Changes in the ligamentum flavum diameter of group DVIII were compared with those of groups DVI and DVII. *p < 0.05.
