Lumbar disc herniation Lumbar disc herniation is mainly due to the lumbar intervertebral disc in different degrees of degenerative changes, under the action of external factors, the intervertebral disc fibrous ring rupture, the nucleus pulposus tissue from the rupture of the protruding (or out) in the posterior or vertebral canal, resulting in adjacent tissues such as spinal nerve roots, spinal cord, etc., suffered from stimulation or compression, resulting in lumbar pain, one side of the lower limbs or both lower limbs numbness, pain, and so on. A series of clinical symptoms. What causes lumbar disc herniation? The basic factor of lumbar disc herniation is degenerative changes in the intervertebral disc, but why does the lumbar disc degenerate? What kind of people are prone to lumbar disc herniation? Countless scientists have been working on this for a number of years, and its exact mechanism is currently unknown. According to current research, lumbar disc herniation is related to the following factors: 1, the structure of the spine: factors of spinal deformity, spinal physiological curvature of the spine is easy to cause biomechanical changes in the spinal column, thereby accelerating or leading to disc degeneration. 2, physiological factors: age – lumbar disc degeneration, but what people are prone to degeneration? 2, physiological factors: age – the incidence of lumbar disc herniation in the middle-aged 30-50 years old the highest, and disc herniation in the elderly population is also a higher incidence of older patients are more common with old lesions, and more associated with lumbar spinal stenosis. Sex – lumbar disc herniation is more common in men than in women, and it is generally believed that the ratio of men to women is 4 to 12:1. Height – the incidence of lumbar disc herniation is high in men over 1.8m and in women over 1.7m. Weight – generally too obese or too thin people with high incidence of lumbar disc herniation. 3.Genetic factors: among people with positive family history, the relative risk of lumbar disc herniation before the age of 21 is about 5 times higher than that of normal people. Occupational factors: the incidence of lumbar disc herniation is significantly higher among long-term office workers, drivers, long-term stooping laborers (surgeons, etc.), long-term load-bearers, and long-term standers (teachers, etc.). 5, trauma factors: children and adolescents with disc herniation is often associated with acute trauma such as lumbar sprain, spinal fracture. 6, smoking factors: studies have shown that nicotine in the cigarette will make blood vessels contract, lumbar intervertebral disc blood supply is reduced, easy to occur degenerative changes, and the longer the smoking time, the higher the incidence of disc herniation. 7, underlying diseases: some diseases can lead to increased atherosclerosis, affecting the blood supply to the intervertebral disc tissue, thus leading to or accelerating disc degeneration, the most common such as diabetes, atherosclerosis, hyperlipidemia and so on. 8, pregnancy: in women’s pregnancy, will make their lumbar load increase, easy to induce lumbar intervertebral disc herniation.
