The advantages of minimally invasive spine technology are: less trauma, less bleeding, less muscle and soft tissue damage, and faster postoperative recovery. Especially for lumbar degenerative disorders, including (lumbar disc herniation/dislocation, lumbar spinal stenosis, lumbar spondylolisthesis, lumbar segmental instability, lumbar degenerative scoliosis). 1. Among them, for lumbar disc herniation/dislocation and lumbar spinal stenosis. The best minimally invasive techniques are currently spinal endoscopic techniques, including (1), lateral intervertebral foraminoscopy (PLED): a percutaneous endoscopic technique to remove the nucleus pulposus and release nerve root compression. This technique is operated under direct vision, decompression is more complete, incision is about 0.7CM, postoperative symptom improvement rate is better, clinical satisfaction rate can reach about 90-95%. (2), posterior discoscopy (MED): the incision is about 1.5 CM, operated under direct vision, operated under direct vision, the nerve root decompression is complete and relatively safe, because the discoscopy system is a microscopic endoscope, the operating field can be magnified 64 times, the fine structure is easy to identify, so it is not easy to damage the nerve root, very safe. These two techniques have been developed internationally in the last 10 years and are the most advanced minimally invasive techniques available. It is important to emphasize that this technique is not a percutaneous excisional suction, radiofrequency, laser or ozone technique. The postoperative results of this technique are comparable to those of open surgery, but with smaller incisions and faster postoperative recovery. 2. For patients with lumbar spinal stenosis, lumbar spondylolisthesis, lumbar segmental instability, and lumbar degenerative scoliosis, the best surgical procedure is the minimally invasive technique of microscopic decompression + canal assist (including Mis-TLIF, Mis-ALIF, Mis-DLIF). The advantages of this technique are: less intraoperative bleeding, significantly lower postoperative infection rate than traditional open surgery, and faster postoperative recovery. However, not all such patients are suitable for this type of surgery, and only patients with fewer than 3 segments are suitable. The advantages of minimally invasive spine technology 1, less damage The small incision avoids extensive stripping and violent stretching of the lumbar back muscles, which reduces the damage to the stability of the lumbar spine to almost zero. 2, less bleeding disc herniation due to long-term compression of the herniated part, resulting in inflammatory expansion of the epidural venous plexus, open surgery is sometimes difficult to stop bleeding, can only be completed under strong suction, coupled with the stripping of the lumbar back muscle bleeding, bleeding is large, usually need routine blood transfusion 300-800ml. It can be magnified 64 times and can directly stop bleeding by electrocoagulation, with little bleeding and basically no blood transfusion. This surgery is the same as the open surgery in terms of pulp nucleus removal and lateral saphenous fossa enlargement, and it can be performed under direct vision to remove the pulp nucleus and enlarge the nerve root canal. Especially for the free nucleus pulposus, it can directly deal with the lateral saphenous fossa stenosis and nerve root adhesions, so the effect is greatly improved; 4, relatively safe Because the discoscope system is a microscopic endoscope, the operative field can be magnified 64 times, and the fine structure is easy to identify, so it is not easy to damage the nerve root, which is very safe; 5, fast recovery after surgery Conventional surgery often requires 3 to 4 weeks of bed rest, 14 days to remove stitches, and 3 months to resume general light physical work. Work. With intervertebral discoscopic nucleus pulposus removal, the patient can recover faster, and can go to the ground 2-3 days after surgery; with lateral foraminoscopy (PLED), the patient can go to the ground immediately after surgery.
