Lumbar disc herniation is the protrusion of the nucleus pulposus after disc degeneration or rupture, and the protruding nucleus pulposus can lead to pressure on adjacent nerves, causing pain and numbness symptoms in the lower limbs. The treatment method is chosen by the degree of protrusion. If the disc is simply herniated and has not yet prolapsed, that is, the disc has not yet ruptured, conservative treatment can be taken, and most patients have obvious improvement in symptoms after conservative treatment; if the disc is prolapsed, the nucleus pulposus will compress the spinal canal and nerve roots, and the effect of conservative treatment is poor, and the patient’s symptoms will improve significantly after the nucleus pulposus is removed by surgery and the compression is lifted.
