Intervertebral foramen endoscopic nucleus pulposus removal is a surgical method that uses an endoscope to remove the nucleus pulposus, nerve roots, diseased tissue, and proliferating bone tissue in the dural sac.
 

Principles of Treatment
Intervertebral foramen endoscope thoroughly removes protruding or prolapsed nucleus pulposus and hypertrophic bone outside the safe triangle area of the intervertebral foramen and the fibrous ring of the intervertebral disc to relieve pressure on nerve roots and eliminate pain caused by nerve compression. Its surgical method is a minimally invasive spinal surgery system composed of specially designed intervertebral foramen endoscope, corresponding minimally invasive spinal surgical instruments, imaging and image processing systems, etc. While completely removing protruding or prolapsed nucleus pulposus, bone hyperplasia can be cleared, spinal stenosis can be treated, and damaged annulus fibrosus can be repaired using radiofrequency technology.
 

Surgical procedure
Indications for endoscopic nucleus pulposus ablation through intervertebral foramen
Lumbar disc herniation: compresses nerves, causing lower back pain, lower back and leg pain, restricted walking, intermittent claudication, etc.
Lumbar discogenic lower back pain: refers to the condition where the protrusion of the intervertebral disc is not obvious, but the lower back pain is obvious and recurrent, and conservative treatment is ineffective. At this point, the intervertebral disc has already suffered structural damage, causing pain for the patient.
Lumbar intervertebral foramen stenosis: Middle aged and elderly patients with lower back and leg pain may experience intervertebral foramen stenosis due to bone spurs or thickening of ligaments, leading to obstruction of nerve channels. Expanding the intervertebral foramen can achieve nerve decompression.

Postoperative precautions
1. After surgery, absolute bed rest for 24 hours is generally required.
During bed rest, you can lie flat or on your side, and turn over, but try to keep your body perpendicular to the bed surface. Do not lie half down or twist.
After 3.24 hours, patients can get out of bed and move around. For elderly, weak, or overweight patients, it is generally required to extend their bed rest time by 12-24 hours.
It is generally recommended to rest in bed for 1-2 weeks after surgery, wearing a waist circumference to get out of bed, eat, wash, use the bathroom, and engage in appropriate indoor activities.
After 1-2 weeks, you can moderately increase your activity level, such as taking outdoor walks or doing simple household chores. However, you should not bear weight on your waist (i.e. not moving, lifting, or carrying), and try not to bend over, sit or stand for long periods of time. Minimize intervertebral disc pressure as much as possible and promote fibrous ring repair.
4. Wear waist circumference when getting out of bed or sitting
It is recommended to choose a wide waist circumference, supported by hard objects such as steel plates. After wearing the waist circumference on the bed, sit up or move out of bed; The wearing time for waist circumference is generally about one month, and for patients who are physically weak or overweight, it may be extended by 2-4 weeks depending on the situation.
Wearing waist circumference for too long can lead to muscle atrophy in the lower back. Therefore, during the wearing process, it is important to exercise the lower back muscles moderately and gradually reduce the frequency and duration of wearing before removing the waist circumference. Otherwise, after removing the waist circumference, it is easy to experience discomfort such as back pain.
5. Exercise time
During bed rest, it is advisable to perform exercises such as raising straight legs and hooking feet to avoid nerve root adhesion; Secondly, it can prevent the formation of lower limb venous thrombosis; Thirdly, it can avoid discomfort such as leg weakness and powerlessness when getting out of bed. After one month, you can selectively engage in lumbar muscle function exercises.
6. Keep bowel movements unobstructed
When constipation occurs, laxatives can be used to prevent an increase in abdominal pressure caused by excessive force, which can impact the intervertebral disc and lead to recurrence. Take cough suppressants as early as possible when coughing, as severe coughing can also lead to increased abdominal pressure and increase the risk of recurrence.
7. Smoking and alcohol are prohibited.
