1, the introduction of intervertebral foramoscopy technology 1, through the intervertebral foramen route to enter, endoscopic direct vision operation, each relevant anatomical structures such as intervertebral disc, fiber ring, posterior longitudinal ligament, dural sac, nerve roots, etc. are levels clearly presented on the screen, high safety, thorough surgery. Li Yuqian, Department of Orthopedics, Nantong Third People’s Hospital 2, special bendable bipolar radiofrequency electrodes in the surgery in good hemostasis, ablation off the tissue of the adherent nerve, and create a clear field of view, can perform fiber molding, disc-derived pain nerve destruction. 3, intervertebral foraminoscopy technology purpose directly, the patient immediately after the operation to the ground, oral antibiotics can be. Patients are less traumatic, less painful, and have a shorter hospital stay. Second, intervertebral foraminoscopy indications 1, persistent or recurrent radicular pain. 2.Root pain is heavier than lumbar pain. If the symptoms of lumbar pain are greater than leg pain, patients with moderate or less bulging can do cryogenic plasma myeloplasty first. 3.Invalidated by strict conservative treatment. Including the use of steroidal or non-steroidal anti-inflammatory painkillers, physical therapy, homework or condition training procedures, conservative treatment is recommended for at least 4-6 weeks, but if there is a progressive worsening of neurological symptoms, immediate surgery is required. 4. No history of substance abuse or psychological disorders. 5, Positive straight leg raise test and difficulty bending. 6.In order to precisely determine the location and nature of the herniated or prolapsed nucleus pulposus, as well as the intervertebral foraminal osteophytes, thorough imaging examinations should be performed before surgery, especially CT and MRI are important means to precisely determine the size, location and nature of the nucleus pulposus. III. Summary of the advantages of intervertebral foraminal technique 1. Minimally invasive Lateral approach, avoiding interference with the spinal canal and nerves by posterior surgery, without biting off the vertebral plate, without destroying the paravertebral muscles and ligaments, and with no effect on the stability of the spine. 2.The purpose is direct. Any herniated disc fragment can be removed. 3.Wide indications Can deal with almost all types of disc herniation, some spinal stenosis, intervertebral foraminal stenosis, calcification and other bony lesions. 4.Low trauma Low chance of thrombosis and infection; no postoperative scarring at important posterior structures leading to adhesions of the spinal canal and nerves. 5.High safety Local anesthesia, which can interact with the patient during the operation, does not hurt the nerves and blood vessels; basically no bleeding, clear surgical field, greatly reducing the risk of misoperation. 6.Fast recovery The next day after surgery, you can go down to the ground and resume normal work and physical exercise in 3-6 weeks on average. 7.High patient satisfaction Immediate pain relief, self-care of urine and stool, simple care, oral antibiotics can be taken, feasible outpatient surgery; skin incision is only 7 mm, in line with the aesthetic point of view. 8.Wide range of expansion The use of new biomaterials can be feasible for artificial nucleus pulposus and artificial disc replacement; combined with percutaneous fixation technology, the fusion and fixation of spinal slippage and instability can be completed in a minimally invasive manner; this basic platform can be easily extended to cervical disc endoscopic surgery.
