Ligamentum flavum hypertrophy refers to the thickening of the ligamentum flavum that occurs in the spinal canal due to metamorphosis or other pathological reasons. Once the ligamentum flavum is hypertrophied, it is not possible to improve the ligamentum flavum through exercise, but it is possible to prevent the further development of the ligamentum flavum hypertrophy, and to improve the symptoms of nerve compression. Ligamentum flavum hypertrophy is caused by prolonged acute and chronic injury stimulation and ageing, resulting in fibrous hyperplasia and triggering ligamentum flavum hypertrophy, which can be clarified by spinal CT or MRI, and can lead to spinal stenosis, and most of the time accompanied by spinal cord nerve compression, resulting in nerve compression symptoms. Patients with hypertrophy of the ligamentum flavum should pay attention to maintaining good posture, avoiding prolonged sitting and standing, avoiding repeated bending of the head and weight-bearing, appropriate sports such as swimming, and appropriate functional exercises for the lumbar and dorsal muscles, such as the small swallow fly, five-point support, and so on. If the hypertrophy of the ligamentum flavum leads to spinal stenosis, causing spinal nerve compression symptoms, you should actively cooperate with your doctor to clarify the diagnosis and treatment plan and carry out targeted treatment.
