Intervertebral foraminoscopy is an emerging technology in the field of orthopedics, which came into being with the new demand for minimally invasive surgical techniques and is now mainly applied to the treatment of lumbar disc herniation. It is accepted by more and more patients because of its advantages such as small trauma, fast postoperative functional recovery and no obvious scar formation on local skin. I. What is intervertebral foraminoscopy technique? Intervertebral foraminoscopic instrumentation consists of an endoscope, a light source system, a video recording and monitoring system, and an operating system, which in turn consists of specialized instruments, radiofrequency ablation, etc. The procedure is performed by first puncturing the patient’s body from the lateral or posterior side, placing the channel and endoscope to the disc herniation through the intervertebral foramen safety triangle, and performing the procedure outside the disc fibrous ring, where the herniated nucleus pulposus, nerve roots, dural sac and hyperplastic bone tissue can be clearly seen under direct endoscopic vision. Special instruments are then used to remove the herniated tissue, remove the hyperplastic bone, and repair the broken annulus fibrosus. The surgery is performed under local anesthesia with a 7mm incision, the size of a soybean grain, and less than 20ml of bleeding, with only one stitch after surgery. It is the least traumatic and most effective minimally invasive treatment for disc herniation of its kind. Intervertebral foraminoscopy is an emerging technology in the field of orthopedics, which was born with the new demand for minimally invasive surgical techniques and is now mainly used in the treatment of lumbar disc herniation. It is accepted by more and more patients because of its advantages such as small trauma, fast postoperative functional recovery and no obvious scar formation on local skin. Second, the indications of intervertebral foraminoscopy technology and postoperative rehabilitation. Intervertebral foraminoscopy technology has a wide range of indications, and has obvious efficacy in the treatment of most types of disc herniation, partial spinal stenosis, discogenic back pain and other diseases in the lumbar spine segment. Patients recover quickly after surgery and can get out of bed on the 2nd postoperative day and be discharged from the hospital 3 days after surgery. Lumbar disc herniation is caused by accumulation of injuries on the basis of degeneration, and accumulation of injuries will aggravate the degeneration of the disc, so the focus of prevention and postoperative rehabilitation is to reduce accumulation of injuries. Therefore, prevention and postoperative rehabilitation should focus on reducing the accumulation injury. Normally, you should have a good sitting posture to avoid overloading the lumbar spine, and get out of bed within 2 months after surgery under the protection of lumbar circumference, avoiding weight bearing and repeated bending, twisting and other exercises that increase the load on the lumbar spine, and combining with functional exercises of the lumbar back muscles to avoid recurrence after surgery.
