The main symptoms of lumbar disc herniation are lumbago, leg pain and numbness, foot pain and numbness, and in severe cases, difficulty in walking and standing; lumbar spinal stenosis patients mainly show weakness, pain and numbness, intermittent claudication, intermittent claudication is to walk a certain distance on the legs to appear weakness, pain or numbness, and after a few minutes of rest, they can still walk about the same distance, but the overall development trend is that the distance walked is getting shorter and shorter. It seriously affects the life and work of middle-aged and elderly people, and in serious cases, they lose the ability to take care of themselves. Tianjin First Central Hospital Pain Division He Yongjin lumbar disc herniation and lumbar spinal stenosis in the past have to open surgery to treat, cut and separate the lumbar spine back of the skin muscles and tissues, exposing the lumbar spine of the bony structure, cut off the obstacles to the removal of the protruding disc of the spinous processes, vertebral plate, joints and other bony structures, set aside the nerves, excision of the protruding disc of the compression of the nerve root, which destroys the lumbar spine of the bony structure, which will bring about an effect on the stability of lumbar spine, lumbar spine loss of the lumbar spine. This destroys the bony structure of the lumbar spine, thus affecting the stability of the lumbar spine, and destabilization of the lumbar spine will bring the patient one problem or another. Therefore, the adjacent lumbar segments must be fixed with steel plates and nails. However, new problems will arise: 1. The movement of lumbar vertebrae is realized by the coordinated movement of joints between lumbar vertebrae segments. If one or two of the joints of the segments are fixed, the function of the fixed joints will be compensated by other lumbar vertebrae joints, and the degeneration of other joints and intervertebral discs will be accelerated significantly in the long run, and the patients will have new symptoms such as lumbar and leg pains and numbness, etc., so how do we solve the new problems of the patients? 2. Due to the large incision, the normal anatomical structure of the lumbar spine’s muscles, ligaments, bones, blood vessels, nerves and other tissues are damaged, and the loss of normal structure will form a huge scar after healing, which will not only affect the normal function of the patient, but also make it difficult to solve the discomfort in the lumbar region due to tissue adhesion, and with the absence of a normal anatomical structure, the risk of reopening the surgery can be imagined, and who will solve the pain problem of the patient after surgery? Who will solve the pain problem of patients after surgery? So what is the treatment for lumbar disc herniation and lumbar spinal stenosis? The consensus of spine experts around the world is that the less trauma the better, and the less impact on spinal stability the better. It is important to remove the herniated discs, but also to remove as little or as little of the patient’s bone as possible. This is the background of the development of intervertebral foramenoscopy technology, which, as the name suggests, uses a mirror to remove the herniated disc through the intervertebral foramen. The mirror is like a gastroscope with a light source and a high-definition camera system, which provides the doctor with a clear, magnified field of vision. Under the mirror, the nerves, blood vessels, ligaments, discs and other tissues are clearly differentiated, which ensures safety, minimal tissue damage, complete resection of the diseased disc, and complete release of the compressed nerves. So when a patient asks me about safety, my answer is: very safe! The intervertebral foramen is a natural foramen of the human lumbar spine, through which a mirror is placed to the site of the herniated disc, the herniated disc is removed, the compressed nerve root is loosened, the normal disc is preserved so that it can perform its normal function, and the intervertebral space is not narrowed, which is a perfect solution to all of the problems of the open lumbar spine surgery. Intervertebral foraminoscopy is the core technology for the treatment of lumbar disc herniation and lumbar spinal stenosis, and its long-term efficacy and safety are higher than that of open surgical treatment. The incision of intervertebral foraminoscopy is only 7 millimeters, which does not move the patient’s bones, does not need to separate the patient’s muscles, ligaments, blood vessels and other tissues, and has a short hospital stay, low cost, fast recovery, and reliable therapeutic efficacy.
