Lumbar disc herniation is a diagnosis of Western medicine, Chinese medicine does not have the name of this disease. Instead, the disease is categorized under the category of “lumbago” and “lumbar leg pain”. Lumbar disc herniation is scientifically defined as a disease in which the nucleus pulposus protrudes from the annulus fibrosus and compresses the nerve root, resulting in low back pain as the main manifestation of the disease. It is one of the more common lumbar disorders in clinical practice, and is a common and frequent disease in orthopedics and traumatology. It is mainly due to the fact that the various parts of the lumbar intervertebral discs (nucleus pulposus, annulus fibrosus and cartilage plate), especially the nucleus pulposus, have different degrees of degenerative changes, and the nucleus pulposus ruptures under the action of external factors. As a result, the adjacent tissues, such as spinal nerve roots and spinal cord, are irritated or compressed, resulting in a series of clinical symptoms such as lumbar pain, numbness and pain in one or both lower limbs. Etiology: (1) Degenerative changes of lumbar intervertebral discs: under normal circumstances, the lumbar intervertebral discs are often compressed by body weight, coupled with the lumbar region is often flexion, backward extension and other activities, it is easier to cause lumbar spinal discs greater extrusion and wear, especially in the lower lumbar region of the intervertebral discs, thus producing a series of degenerative changes. (2) External force: about 1/3 of the patients have different degrees of trauma history. Common forms of trauma include overloading of the lumbar region when bending over to carry heavy objects, moving or lifting heavy objects when the lumbar muscles are not yet sufficiently tensed, various forms of lumbar sprains, sudden straightening of the back after a long period of bending over, and falling with the hips on the ground, etc. These traumatic injuries can make the intervertebral discs in the instantaneous pressure on the nucleus pulposus under tension exceeding the stress of the annulus fibrosus, resulting in fibrous rupture, and protruding nucleus pulposus from the ruptured portion. Some people in daily life and work, there are often long-term lumbar force improper, excessive force, posture or position of the incorrect and so on. For example, loading and unloading workers bend over and lift heavy objects for a long time, and drivers are in a sitting position and upside down for a long time. These long-term repeated external forces caused by minor injuries. The cumulative effect on the lumbar spine disc, aggravating the degree of degeneration. (3) The weakness of the intervertebral disc’s own anatomical factors ① The lumbar intervertebral disc gradually lacks blood circulation after adulthood. Repair ability is also poor, especially after the above degeneration, the repair ability is more powerless. (2) The lumbar intervertebral disc is weak in the posterior lateral fibrous annulus, and the posterior longitudinal ligament in the lumbar 5, sacral 1 plane, the width of the lumbar intervertebral ligament is significantly reduced, and the strengthening effect of the fibrous annulus is significantly weakened. (4) predisposing factors ① sudden weight bearing or flash waist: sudden increase in lumbar load, especially rapid bending, lateral flexion or rotation, is the main reason for the formation of fibrous ring rupture. ② lumbar trauma: when the violence is strong and does not cause fracture dislocation, it is possible to make the degenerated nucleus pulposus protrude. In addition, lumbar puncture examination or after lumbar anesthesia may also produce disc herniation. ③ Improper posture. Nucleus pulposus herniation can also occur when the abdominal pressure increases. ⑤ Cold and dampness. Cold or dampness can cause small blood vessel contraction and muscle spasm, which increases the pressure on the intervertebral disc and may also cause the degenerated disc to fracture. External factors such as excessive weight-bearing or rapid bending, lateral flexion, rotation to form a rupture of the annulus fibrosus, or lumbar trauma, improper posture in daily life and work can also occur in lumbar intervertebral disc herniation. (5) Racial and genetic factors The incidence rate of colored people is lower, for example, the incidence rate of Indians and black Africans is obviously lower than other ethnic groups.
