“Low back pain is a common disease, and according to statistics, its incidence is second only to the flu. Although this disease may develop in people of all ages, but still mainly in the middle-aged and elderly, is a major problem for the elderly. Data show that the vast majority of back and leg pain is related to lumbar intervertebral disc lesions. The traditional view is that painful symptoms may only occur if the disc has herniated and compressed the nerve root, but this statement does not explain all clinical phenomena. In some patients, the lumbar disc herniation is mild and minimal in extent, yet they exhibit severe signs and symptoms. In other patients, the lumbar disc herniation is very severe, but their clinical symptoms are mild. In recent years, the results of a large number of experimental studies in neurobiochemistry and immunology tell us that the non-bacterial inflammation caused after a lumbar disc herniation is more closely related to the patient’s symptom expression and is the underlying lesion of lumbar disc herniation, and the removal of this non-bacterial inflammation is an important task in the treatment of lumbar disc herniation. How the disc is composed The intervertebral disc is located between two vertebral bodies and is the link between the vertebrae. It usually consists of three parts: the cartilage plate, the annulus fibrosus, and the nucleus pulposus. Each intervertebral disc contains two cartilage plates that cover the two adjacent vertebrae. The fibrous ring is attached between the two cartilage plates and centrally encloses the nucleus pulposus. Under normal conditions, the three discs form a closed “container” that is very flexible and tough. The symptoms of “lumbar protrusion” are rooted in inflammation. The nucleus pulposus itself can cause a chemical inflammation of the nerve roots, which can cause significant pain. If the fibrous ring surrounding the nucleus pulposus ruptures, the nucleus pulposus can leak out and the inflammatory material therein can irritate the nerve root and cause pain. When inflammation involves the adjacent nerve tissue to form radiculitis, it can produce symptoms such as nerve damage. In addition, studies have shown that patients with lumbar disc herniation also have an abnormal immune status that may be related to the occurrence of an autoimmune reaction in the disc tissue. Autoimmune reactions can also lead to edema or inflammation of the nerve roots, which can cause the corresponding symptoms. “The common treatment methods for lumbar protrusion are not effective. The common treatment options for lumbar protrusion include oral medications, acupuncture, acupressure and other physical therapy, as well as paravertebral, lateral epidural space and epidural block. Most oral medications can only relieve symptoms, and physical therapy is often ineffective in eliminating inflammation. Nerve block is to inject the drug into the lesion locally, so that the drug is in full contact with the lesion, and the efficacy is more accurate, usually once every 7 days for a course of treatment, 3 to 5 times. However, the duration of the efficacy of these conventional blocks is sometimes less certain, and often some people’s pain and other symptoms return soon after the end of treatment. Not only are patients dissatisfied, but doctors also lose confidence the more they treat them. The reason for this is that the lesions of the lumbar discs are generally long, ranging from a few months to several decades, and the local inflammatory changes have become deep-rooted after years of accumulation, so it is difficult to eliminate them completely with simple blocks. The latest interventional treatment The treatment of inflammatory lumbar disc herniation is now mostly done by minimally invasive neurointerventional treatment. It involves placing a special catheter into the lesion site under the mediation of imaging tools, and using a microinjection device to give anti-inflammatory and analgesic drugs and other drugs on a long-term and continuous basis to eliminate the inflammation as cleanly as possible. On this basis, together with surgery or collagenase lysis, we can generally achieve more satisfactory results. It not only relieves the patient’s pain, but also gives the doctor confidence. The middle-aged and elderly prevent “lumbar protrusion” precautions 1, maintain good habits, prevent the waist and legs from getting cold, prevent excessive strain. 2, stand or sit in the correct posture. The spine is not correct, which will cause uneven force on the intervertebral discs, which is the hidden root cause of disc protrusion. The correct posture should be “standing like a pine, sitting like a bell”, chest up, waist straight. The same posture should not be maintained for too long, appropriate in situ activities or low back activities, can lift the low back muscle fatigue. 3, exercise leg bending amplitude is not too large, otherwise not only will not achieve the desired purpose, but also cause disc protrusion. 4, do not bend when lifting heavy objects, should first squat down to get heavy objects, and then slowly get up, try to do not bend.
