Surgery to remove the nucleus pulposus for lumbar herniation is generally not harmful to the body, but improper operation can cause some complications such as anterior flexion and posterior extension inflexibility. Nucleus pulposus removal is a surgical method to remove the nucleus pulposus through the intervertebral foramenoscope. It is mainly applied to patients with lumbar disc herniation or prolapsed nucleus pulposus who have failed conservative treatment. Nucleus pulposus removal surgery is generally safe and patients can return to normal with remarkable results. However, some complications such as inflexibility in forward flexion and backward extension, recurrence of lumbar disc herniation, and damage to the surrounding small joints can be caused if the operation is operated incorrectly or if the rehabilitation is not done properly after the operation. After removing the nucleus pulposus in lumbar herniation surgery, it is recommended to have regular checkups, avoid heavy physical labor, and combine work and rest. If any discomfort occurs, it is recommended to go to the hospital in time for early and regular treatment.
