A prolapsed nucleus pulposus is a prolapsed lumbar disc, and once the nucleus pulposus is prolapsed, most cannot go back on its own. The nucleus pulposus tissue is a foreign body in the spinal canal, and compression of the nerve will cause symptoms. In some people, the nucleus pulposus of the lumbar disc can be slowly reduced and absorbed by itself without causing symptoms, and can be treated conservatively. However, if the nucleus pulposus is too large, the amount of tissue prolapsed from the nucleus pulposus is large, and the nerve compression is tight, it may not be self-absorption, so it should be removed through surgery, including open surgery and minimally invasive intervertebral foraminal surgery. Lumbar nucleus pulposus prolapse is also a manifestation of herniation, which is a more serious herniation. However, not every patient will have significant sequelae. As long as the degree of its compression of the nerve is not heavy and not long, or if it is simply numbness or pain, then with effective treatment, whether conservative or surgical, there can be no significant sequelae. Severe disease may have sequelae, as follows: 1, prolonged compression or compression of heavier cases, may cause nerve injury sequelae, such as numbness, legs and feet without strength; 2, acute compression may cause urinary and fecal problems, some patients need surgical treatment. If the cauda equina nerve injury requires emergency surgical treatment, otherwise there may be numbness in the anal region or urinary and fecal disorders.
