At present, lumbar disc herniation is mostly treated by traditional open surgery, which is traumatizing to the muscles of the lumbar back, and some patients are reluctant to undergo the surgery due to more concerns, resulting in delayed condition. In order to satisfy the patients’ desire to get the best treatment effect with minimum trauma, our spine department takes the lead in carrying out the international advanced intervertebral foraminoscopy technology, which opens up a new way for the treatment of lumbar disc herniation patients. What is intervertebral foraminoscopy? The purpose of the minimally invasive intervertebral foramenoscopy technique is to enter the intervertebral foramen from the side or the back of the patient’s body, and completely remove the protruding or prolapsed nucleus pulposus and hyperplastic bone outside of the intervertebral foramen’s safety triangle and intervertebral disc fibrous ring to relieve the pressure on the nerve root, and to relieve the obstruction of circulation in the lateral saphenous fossa due to compression by the herniated intervertebral disc, as well as the oedema and aseptic inflammation of the nerve root. The procedure is performed through a specially designed intervertebral foraminoscope and the corresponding supporting minimally invasive spinal surgical instruments, imaging and image processing systems, as well as bipolar electrocoagulation and ozone therapy instrumentation, which together form a minimally invasive spinal surgical system. Why is laminectomy the most minimally invasive and safe lumbar disc surgery? “Intervertebral foramenoscopy technology” enters through the intervertebral foramen pathway, endoscopic operation, the relevant anatomical structures such as intervertebral discs, fibrous annulus, posterior longitudinal ligament, dural sacs, nerve roots and so on are clearly presented on the screen at all levels, with high safety and thorough surgery, it is the most minimally invasive, safest and economical technology at present; at the same time, it is still in the rapid development. Meanwhile, this technology is still developing rapidly, and has been applied to artificial disc and nucleus pulposus replacement, fusion under intervertebral foramenoscopy with percutaneous technology for internal fixation, minimally invasive treatment of spinal tuberculosis and minimally invasive treatment of cervical intervertebral foramenoscopy in a large amount of new fields, and its clinical efficacy and academic value are attracting more and more orthopedic surgeons to focus on the expansion of this technology. Intervertebral foramenoscopy has advantages that open surgery does not have: 1, minimally invasive: avoiding the interference of traditional surgery on the spinal canal and nerves, not destroying the vertebral plate, muscles and ligaments, and not affecting the stability of the spinal column; 2, wide range of indications: it can treat almost all types of herniated discs; 3, aesthetically pleasing: the surgical incision is only 0.7-37.5px, which is in line with the aesthetics point of view; 4, safe: local anesthesia anesthesia, interaction with patients, no injury to nerves and blood vessels during the operation, and no injury to the patient. High safety: local anesthesia, interaction with the patient during the operation, no injury to the nerves and blood vessels, basically no bleeding; 5, fast recovery: the next day after the operation can get out of bed and return to normal work in an average of 4 weeks; 6, low cost: no need for built-in material, reduce the patient’s financial burden and the burden of medical insurance. The advantages of intervertebral foramenoscopy surgery over other minimally invasive surgeries are obvious: At present, minimally invasive lumbar spine surgery is mainly an interventional method. The interventional methods available include collagenase dissolution, percutaneous excision and aspiration, laser vaporization (PLDD), plasma nucleus pulposus, ozone, radiofrequency ablation, etc. However, all of the above methods are indirect decompression. However, the above methods are indirect decompression, only for some cases of inclusion-type herniation, can not completely remove the lesion nucleus pulposus, especially the compression of the nerve tissue, can not repair the broken annulus fibrosus, necrotic tissues need to rely on the body’s natural absorption, long time, pain, high recurrence rate. 90’s development of the posterior discectoscope will be minimally invasive concept a big step forward, the majority of orthopaedic surgeons gradually realized that with the emergence of new technologies and new materials, the majority of orthopaedic surgeons are now more and more advanced and more advanced. The majority of orthopedic surgeons gradually realized that with the continuous emergence of new technologies and materials, minimally invasive technology was inevitably the direction of surgical development. However, the surgical access and treatment process of posterior discoscopy (MED) is consistent with small-incision open surgery, which involves opening the vertebral plate, stripping the muscles and ligaments, interfering with the spinal canal, and pulling the nerves (to a lesser extent than the open surgery); it is prone to intraoperative bleeding, interfering with the field of view and increasing the risk; it cannot be applied to the treatment of extreme lateral herniation and discogenic pain; and the postoperative scar tissue is prone to cause adhesion to the vertebral canal and the nerves.
