Lumbar spine injury lumbar leg pain and numbness and even limp years of continuous overload consumption of physical energy will appear after the age of the lumbar leg pain, the beginning is still tolerable pain, with the growth of age, lumbar leg involvement pain will become more and more serious, and even lead to difficult to walk. This is a sign that the lumbar spine has become a serious problem and the lumbar spinal canal has become narrower. Lumbar spinal stenosis is a manifestation of spinal stenosis in the lumbar spine, which is mainly manifested by long-term recurrent lumbar pain, sometimes the pain can be radiated to the lower limbs, usually with lumbar pain first, and gradually leg pain, and a small number of people will have serious symptoms such as numbness and weakness of the lower limbs, muscle atrophy, urinary and fecal disorders, and even intermittent claudication. It is worth mentioning that the most obvious feature of neurogenic claudication is that the symptoms are aggravated when the lumbar spine is in extension and relieved when it is bent. This is because the volume of the lumbar spinal canal becomes smaller when the lumbar spine is in extension and larger in forward flexion. Many patients with spinal stenosis feel normal when walking with their hands in a wheelchair or shopping cart, but their pain worsens when standing upright. Because spinal stenosis is a chronic degenerative process, early symptoms are often not obvious and patients often have a less than clear history of chronic low back pain and mild activity limitations. These symptoms often worsen with activity or work and are relieved with rest, but the pain in the lower back and hip usually does not disappear immediately. This is like a water pipe in disrepair, due to the rusting of the inner wall, the thickening of the wall, the narrowing of the lumen, the water coming out is getting smaller and smaller, and finally the lumen is blocked and the water flow is interrupted. Because the symptoms are mild, many patients do not take it to heart and consider it a normal phenomenon of human aging. Imaging is essential Lumbar spinal stenosis will continue to worsen if it is not maintained and treated in a timely manner. In general, patients can choose conservative treatment or surgery. Conservative treatment includes rehabilitation therapies such as massage and exercise, mainly to activate blood and relax tendons and release adhesions to relieve symptoms; surgical treatment is currently the most popular with minimally invasive surgery, which involves removing the vertebral plate, articular processes, ligaments and other structures to expand the volume of the spinal canal, release nerve compression and eradicate the root of the disease under professional equipment. The specific treatment plan can only be carried out after a professional imaging examination. For example, CT or MRI examinations can clarify the degree of lumbar vertebral degeneration, which vertebral body is hyperplastic, and whether the lumbar spine is deformed or combined with other vertebral lesions. If it is accompanied by lumbar spine slippage or scoliosis deformity, it is important to choose advanced professional technical equipment and clinically experienced doctors for surgical treatment so that complications such as vertebral instability can be effectively avoided. How to treat degenerative lumbar spinal stenosis Since degenerative lumbar spinal stenosis causes the volume of the spinal canal to become smaller, in terms of treatment, most doctors advocate surgical treatment. However, non-surgical treatment can be tried for early cases with relatively mild symptoms. 1, non-surgical therapy Medication can relieve pain to a certain extent, mainly using non-steroidal anti-inflammatory and analgesic drugs. However, if these drugs are taken for a long time, they can produce side effects such as digestive tract irritation, leukopenia, liver and kidney function damage, etc. Functional exercise is also part of the non-surgical treatment. Patients can move their lumbar joints and stretch their limbs by means of fitness equipment and some special health exercises. These methods are safe and have certain clinical effects. Various types of physical therapy can be performed such as tension therapy, lumbar muscle strength exercises and anaerobic health training. For soft tissue physiotherapy methods there are also infrared, ultrasonic heat therapy and other items, which mainly improve the blood circulation of the lumbar muscles and nerve tissues, and therefore also have a certain degree of pain relief. The above-mentioned non-surgical therapies only relieve the symptoms to a certain extent, and when the pain develops to the extent that it continuously affects the patient’s normal life and work, then surgical treatment should be considered. 2, surgical treatment In recent years, minimally invasive surgical methods have entered the field of spinal surgery, such as discoscopy, radiofrequency disc ablation, laser disc ablation, etc., which have played an important role in clinical treatment. By treating such patients with the aid of a microscope, we can reduce the trauma to the patient. Usually the skin incision is less than one centimeter, and through a very small skin incision we can remove the herniated lesion nucleus pulposus from the patient and relieve the patient’s symptoms. Moreover, patients recover very quickly after surgery, and the wound heals quickly because of the small window. Minimally invasive surgery is not only safe during surgery, but also has a good healing process and minimal risk. The procedure increases the safety of the patient because it is performed under a microscope, and the very fine anatomical structures of the nerve are clearly distinguished, so damage to these structures is avoided and the risk of surgery is reduced. It is also effective in that it allows full decompression under the microscope, and all structures that are seen to be compressing the nerve under the microscope can be completely removed, and the decompression is very adequate. In addition, the trauma to the spine is minimal, as a very small vertebral plate is opened and the trauma is minimal. At the same time, the patient recovers quickly. Especially in such elderly patients, if they undergo traditional surgery, they can only leave bed in two weeks, but they can leave bed in the second day of minimally invasive surgery, and can be discharged home on the third and fourth day. Daily exercise can prevent lumbar spinal stenosis To prevent lumbar spinal stenosis, it is necessary to first maintain normal lumbar curvature, which can be improved by appropriate exercise at home. If the lumbar curvature is large, you should insist on bending your back and holding your knees with both hands every day, exercising 50-100 times a day, and after a month, you will feel strong legs and less intermittent claudication; if the lumbar curvature is small and tends to become straight, you should exercise the method of back extension, or lie on your back in bed, bend your knees and hold your abdomen, practicing 50-100 times a day, exercising for a month, which can also make the symptoms of early lumbar spinal stenosis The symptoms of early lumbar stenosis can be reduced or even disappeared. People with heavy lumbar work should wear a protective belt at work to prevent excessive load on the lumbar spine.
