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/distension/prolapse, lumbar spinal stenosis, lumbar spondylolisthesis, lumbar segmental instability, lumbar degenerative scoliosis). 1. Among them, for lumbar disc herniation/distension/prolapse and lumbar spinal stenosis, the best minimally invasive technique is the percutaneous endoscopic technique to remove the nucleus pulposus and release the nerve root compression. This technique is operated under direct vision, and decompression is more complete with an incision of about 0.7 cm. The postoperative symptom improvement rate is better, and the clinical satisfaction rate can reach about 90-95%. This technique has been carried out internationally for the last 10 years, and in China for about 5 years. It is one of the most advanced minimally invasive techniques available. It is important to emphasize that this technique is not a discoscopic technique or a percutaneous excision and suction, radiofrequency, laser or ozone technique. The postoperative effect of this technique is comparable to that of open surgery, but its incision is smaller and the postoperative recovery is faster. 2.For patients with low back pain, but the specific cause is not very clear, “selective nerve root closure, discography, epidural imaging, subdural imaging” can be used for diagnostic treatment, that is, to achieve the purpose of surgical treatment, but also to achieve the purpose of clear diagnosis. 3.For patients with severe low back pain, conservative treatment is ineffective, and joint synapse closure is effective (the effect does not last long), percutaneous spinal endoscopy can be used to cut the posterior medial branch of the spinal nerve. 4. For patients with lumbar spinal stenosis, lumbar spondylolisthesis, lumbar segmental instability, and lumbar degenerative scoliosis deformity, the best surgical procedure is the tube-assisted small incision technique (including Mis-TLIF, Mis-XLIF, Mis-ALIF, Mis-DLIF). The advantages of this technique are: less intraoperative bleeding, significantly lower postoperative infection rates than traditional open surgery, and faster postoperative recovery. However, not all such patients are suitable for this type of surgery, and only patients with less than 3 segments are suitable.
