At present, lumbar disc herniation has become a multi-morbidity and common disease among the middle-aged and elderly in modern society. Classification 1, lumbar disc bulge: the protrusion often has a thin outer fiber ring wrapped, the posterior longitudinal ligament is usually not broken, the maximum distance into the spinal canal does not exceed 3mm. 2, lumbar disc protrusion: the protrusion is more than 3mm in height, from the fiber rupture into the spinal canal, some surface covered with posterior longitudinal ligament, surgery is found to be an obvious round projection, cut the posterior longitudinal ligament peritoneum, the protruding nucleus pulveris often automatically from the incision. The herniated nucleus pulposus is often extruded from the incision automatically. 3. Lumbar disc prolapse: The herniated material penetrates the outer layer of the fibrous ring and breaks away from the disc itself, and may be free on the posterior side of the upper or lower vertebral body, or may break through the posterior longitudinal ligament and break free around the nerve root or on the anterior side of the dural shell, and may occasionally break into the dura and compress the spinal cord. The free protrusions may become fibrotic or calcified nucleus pulposus or disc fragments. The shape may be as large as a grain of rice or as large as 20 mm. The main causes are degenerative degeneration of the lumbar disc and trauma. The herniation of the nucleus pulposus occurs mostly on the basis of degenerative disc degeneration, and the pressure of the intervertebral disc is increased by a variety of causative factors. Triggering factors 1, factors that increase abdominal pressure, such as violent coughing, breath-holding constipation, etc., which increases abdominal pressure and disrupts the equilibrium between the intervertebral joints and the spinal canal. 2.Improper posture of the lumbar region, lifting heavy objects on a semi-flexed basis, sudden rotation generates pressure, shear force and forces the nucleus pulposus to prolapse. 3.Multiple factors cause spasm of the lumbar back muscles, which increases the pressure on the intervertebral disc, causing the rupture of the fibrous ring and the prolapse of the nucleus pulposus. 4, excessive load, such as weight-lifting athletes, porters, pit bending operations, etc. 5, long-term vibration overstrain, such as car and tractor drivers in a sitting position and bumpy state for a long time, lumbar disc pressure, long-term strain, aggravating the degeneration and prolapse of the intervertebral disc. 6, spinal deformity and physiological curvature changes, on the basis of which is prone to intervertebral disc degeneration, mainly so that the pressure on the fiber ring is not balanced. 7, acute injuries, such as sprains, contusions and other acute injuries, generally do not cause lumbar disc protrusion, but the injury of the lumbar back muscle group lost the protection of the disc is prone to disc prolapse, so the lumbar injury, just the cause of disc prolapse.
