Once the yellow ligament is hypertrophied, it cannot be made better through exercise, the reason why the yellow ligament is hypertrophied is due to the stimulation of long-term acute and chronic injury, resulting in chronic inflammatory infiltration of the ligament, inflammatory cell secretion, repeated damage to the yellow ligament, thus causing chronic sterile inflammation of the yellow ligament, which eventually leads to fiber hyperplasia and causes hypertrophy of the yellow ligament. The more you exercise, the more likely it is to aggravate the damage to the ligamentum flavum, making the hypertrophy more and more serious, and even leading to calcification of the ligamentum flavum, so the hypertrophy of the ligamentum flavum cannot be made better through exercise.
