Intervertebral Foraminoscopy Technology Intervertebral foraminoscopy is the latest minimally invasive spinal technology for the treatment of lumbar disc herniation and lumbar spinal stenosis. It is known as the “minimally invasive of minimally invasive”. It uses a tube equipped with a cold light source to enter the area of the intervertebral foramen from the posterior side of the patient’s body, and from the safety triangle or synovial position to the diseased disc or disc herniation site, and removes the compression materials around the affected nerve root, such as the nucleus pulposus, hyperplastic bone tissue, and hypertrophic hyperplastic tissue, through small and delicate instruments. The nerve roots are completely “freed” from compression. Compared to other existing minimally invasive spine techniques, it is safer, more widely indicated, more minimally invasive, more definitive, and results in a faster recovery for the patient. 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 damaging the paravertebral muscles and ligaments, and without affecting the stability of the spine. 2. Direct purpose: It is able to remove the protrusion directly and has the best effect. The nerve roots can be seen under the microscope to release thoroughly. 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 can leave scarring at the posterior important structures and cause adhesions of the spinal canal and nerves. 4, high safety: surgery under local anesthesia, intraoperative interaction with the patient, no injury to 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 surgery can be out of bed. 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 disc herniation: compression of nerves, resulting in low back pain, low back and leg pain, limited walking, 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.
