Intervertebral foraminoscopy is the newest and most ideal minimally invasive surgical system in the world for the treatment of herniated discs. It uses a tube equipped with lights, which enters the foramen from the side or rear of the patient’s body. Under direct endoscopic vision, the herniated nucleus pulposus, nerve roots, dural sac and hyperplastic bone tissue can be clearly seen, and then various types of grasping forceps are used to remove the herniated tissue and repair the broken annulus fibrosus, which can completely remove the herniated or prolapsed nucleus pulposus while removing the bone growth and treating spinal stenosis. Compared with other minimally invasive spinal techniques, it is safer, more widely indicated, more minimally invasive, less invasive, more effective and faster recovery. Clinical advantages of intervertebral foraminoscopy: 1. Minimally invasive: the target area is reached through a lateral approach with a skin entrance of only 8 mm, avoiding interference with the spinal canal and nerves in traditional posterior surgery, without biting off the vertebral plate, without destroying the paravertebral muscles and ligaments, and without affecting the stability of the spine. 2.Direct purpose: able to directly remove the protrusion, the best effect. 3.Wide indications : Able to deal with almost all types of disc herniation, some spinal stenosis, foraminal stenosis, calcification and other bony lesions. Traditional open surgery will leave scarring at the posterior important structures and cause adhesions of the spinal canal and nerves. 4.High safety ： local anesthesia, which can interact with the patient during the operation without hurting the nerves and blood vessels; basically no bleeding, clear surgical field of view, greatly reducing the risk of misoperation; 5.Fast recovery ： the next day after the operation, you can go down to the ground. 6, high satisfaction : immediate pain relief, self-care of urine and stool, simple care, very small skin incision, in line with the aesthetic point of view. Which patients can use intervertebral foraminoscopy technique? 1 . Lumbar intervertebral disc herniation: compression of nerves, resulting in low back pain, low back pain, walking limitation, intermittent claudication, etc. 2 . Lumbar discogenic lumbago: the disc herniation is not obvious, but the lumbar pain is obvious, recurrent, and conservative treatment is ineffective. At this time, the intervertebral disc has already appeared structural damage, which causes pain. 3. Lumbar foraminal stenosis: In middle-aged and old-aged patients with low back pain, the intervertebral foramen is narrowed due to bone spurs or ligamentous hypertrophy, resulting in obstruction of the nerve channel. Enlargement of the intervertebral foramen can achieve nerve decompression.
