The number of patients with lumbar disc herniation is increasing, and what is a good method to treat lumbar disc herniation has become a worry for many patients. As the concept of minimally invasive treatment is gaining momentum in various treatment areas, posterior discoscopy may become the direction of future development. What is the “microendoscopic discectomy system”? The microendoscopic discectomy (MED) is an internationally advanced minimally invasive surgical approach to spine surgery. This technology was born in the 1990s, and in 1995 the first generation of the posterior microendoscopic disc nucleus pulposus removal system was developed in the U.S. The second generation of the posterior microendoscopic disc nucleus removal system was put into use, making the treatment of disc disease easy and popular in Europe and the United States. At present, it has become the most advanced minimally invasive spinal surgery method in the world. The system combines advanced technology and clinical perfection, providing patients with a less damage? It is a safe and reliable treatment method with a short course of treatment. It can remove the prominent nucleus pulposus, the hypertrophic ligamentum flavum and the hyperplastic and cohesive synapses and other neurological factors, thus obtaining a curative effect. The advantages of posterior minimally invasive surgery system for lumbar disc herniation 1.Little injury The incision is only 1.5cm, which avoids extensive stripping and violent pulling of the lumbar back muscles and reduces the damage to the stability of the lumbar spine to almost zero. 2.Precision: lateral approach, avoiding interference with the spinal canal and nerves by posterior surgery; no biting of the vertebral plate, no destruction of the paravertebral muscles and ligaments, no effect on spinal stability. 3, high safety: local or epidural anesthesia, intraoperative interaction with the patient, no injury to nerves and blood vessels; basically no bleeding, clear surgical field, effectively avoid the risk of misoperation. 4.Fast recovery: intervertebral discoscopic nucleus pulposus removal with little injury enables patients to get faster recovery with an average hospitalization of about 5 days. 5.Almost no complications: little trauma, low chance of thrombosis and infection; no postoperative scarring at the posterior important structures leading to adhesions of the spinal canal and nerves. 6, wide indications: the intraoperative purpose is direct, and any herniated disc fragment can be removed; it can deal with almost all types of disc herniation, some spinal stenosis, foraminal stenosis, calcification and other bony lesions. 7, high satisfaction of efficacy: immediate postoperative relief of pain and other symptoms, self-care of urination and defecation, simple care. With the continuous improvement of the supporting instruments and the maturity of the surgical technology, the indications of the “posterior discoscopic minimally invasive surgery system” have been broadened from the early treatment of simple posterior lateral herniation of a single segment to the current treatment of various special types of multiple segments. The main indications are disc herniation, lateral saphenous fossa stenosis, central canal stenosis and other lumbar spinal stenosis. Because the surgery is less invasive, it is especially suitable for patients of advanced age, developing adolescents, and patients with hypertension, heart disease, diabetes, etc. who cannot tolerate major surgery. Minimally invasive posterior discoscopy procedure The patient is placed prone on an X-ray viewable surgical bed, and under the surveillance of a bedside C-arm X-ray machine, a guide needle is punctured and positioned, and the surgical channel is sequentially expanded and placed. Under television surveillance, the endoscopic head aspirates part of the lower edge of the lamina and the ligamentum flavum to widen the lamina space, removes the disc medullary tissue, bites away the local hyperplastic meatus and thickened ligamentum flavum, and expands and clears the nerve heel channel. Postoperative rehabilitation after minimally invasive posterior discoscopic surgery After surgery, symptoms such as sciatica in the lumbar region disappeared, and the patient could get out of bed on the same day, and was discharged from the hospital 2-3 days after surgery, still mainly with bed rest. Early stage: functional exercise of the loose leg and lumbar back muscles. Since the introduction of the American pivot mode posterior discoscopy for the treatment of disc herniation, our hospital has treated more than 600 patients, and the surgery Posterior discoscopic nucleus pulposus removal is a new international achievement in minimally invasive spine surgery. The principle of surgery, operation procedure and clinical efficacy have great advantages compared with full open surgery, and it is a mature technology at present. It follows the basic principle of “decompression and stabilization” in spinal surgery, and has a broad development prospect in the treatment of lumbar disc herniation.
