What are the symptoms of bulging and protruding

summary

Lumbar disc herniation and prolapse are pathological changes caused by intervertebral disc degeneration, which only show the difference in the degree of pathological changes.

What are the symptoms of bulging and protruding

First, after the degeneration of intervertebral disc, the firmness of the peripheral tissue of intervertebral disc decreases, and the waist movement and labor operation posture is based on the previous flexion position. At any time of flexion, the intervertebral joint space is in the state of narrow in front and wide in back, and the intervertebral disc deforms under pressure, which makes the nucleus pulposus squeeze backward, resulting in the increase of the pressure in the posterior position of the intervertebral disc.

Second, due to the weakness of the posterior longitudinal ligament, it is difficult to restrict the pressure of the posterior position of the intervertebral disc, so that the intervertebral disc gradually expands backward, but the annulus fibrosus is still intact. It is clinically called disc herniation.

Third: the clinical symptoms of lumbar disc herniation is generally lighter than that of disc herniation. In the process of disc herniation, the degree of disc herniation is light, but there is no obvious symptom of nerve root compression, only dull pain in the waist and radiation pain in the buttock. Although the bulge is not broken, it will still affect the dural sac of nerve root and cause radiculopathy.

matters needing attention

The general symptoms of disc herniation are obvious. The herniated tissue can directly compress the dural sac of nerve root, resulting in root pressure and root pain. Symptoms and clinical manifestations of typical lumbar disc herniation
