Clinically, lumbar hypertrophy refers to the hypertrophy of the ligamentum flavum, which means that the patient’s lumbar spine has hyperplasia and degeneration, which is a kind of degenerative change. After this change occurs, the patient can irritate and compress the dural sac or nerve root in the vertebral canal, and a series of symptoms of nerve compression will appear clinically, such as the patient will feel radioactive tingling in the lumbar region, positive lumbar pressure pain, and difficulty in bending, and the patient has skin sensation loss and muscle strength weakness of both lower limbs. In addition, the patient’s bilateral lower limbs will have decreased skin sensation and muscle strength, and some patients will also have pathological reflexes, etc. The diagnosis can be clarified by taking MRI or CT films of the lumbar spine. In addition, lumbar vertebral hypertrophy can also lead to lumbar spinal stenosis, which can cause intermittent claudication when the patient walks, and often has chronic and persistent pain in the lumbar region and other clinical manifestations.
