First of all, in answering the question of whether minimally invasive surgery can be done for lumbar disc herniation, it is necessary to answer the question of whether lumbar disc herniation needs to be operated. 1, the lumbar disc herniation conservative treatment has no effect, or conservative treatment is effective but recurrent (two to three episodes within a year); 2, the patient lumbar disc herniation attack pain is very intense, even must maintain a certain posture to reduce pain (also known as medical forced position); 3, is the emergence of lower limb weakness, urinary and fecal abnormalities, or combined with lumbar spinal stenosis patients The patients who need surgical treatment. Many of these patients who require surgical treatment can be treated with minimally invasive foraminoscopic surgery. This is because, at present, foraminoscopy technology is very mature, and as long as the indications are properly selected, good treatment results are generally obtained. For young patients who have to use their back for a long time, foraminoscopic surgery is more advantageous; for some elderly patients who are in poor physical condition, such as patients with combined medical diseases (heart disease, cerebrovascular disease, etc.) and cannot tolerate “major surgery”, minimally invasive surgery can also be chosen. The advantages of intervertebral foraminoscopy for the treatment of lumbar disc herniation are: 1. low level of anesthesia, which can be done by semi-body anesthesia or local anesthesia; 2. small trauma, which will not be injured by open surgery, and quick recovery after surgery; 3. less damage to normal tissues, so the stability of the lumbar spine can be well maintained. Typical cases: Case 1, adolescent single-segment lumbar disc herniation. Case 2, adolescent double-segment lumbar disc herniation completed with a single incision. Case three, adolescent single-segment lumbar disc herniation with bilateral symptoms completed bilaterally. Case four, multi-segmental lumbar disc herniation with diagnostic closure followed by responsible lesion surgery. Case V. Minimally invasive surgery case for recurrence of lumbar disc herniation after open surgery.
