Low back pain is one of the common disorders among middle-aged and elderly people, which seriously affects the quality of life of patients! The common causes of these symptoms are lumbar disc herniation, lumbar spinal stenosis, lumbar spondylolisthesis, lumbar spinal tuberculosis or tumor and other disorders, and today we choose the topic of lumbar spinal stenosis to talk about! The age of onset of lumbar spinal stenosis is common in middle-aged and elderly people, mainly manifested as intermittent claudication, i.e. numbness, swelling and pain, weakness and other symptoms in unilateral or bilateral lower limbs after walking 100-500 meters, requiring squatting or bending down to rest for a while before walking again; sometimes symptoms such as numbness or dullness of sensation appear in the lateral calf, dorsum of the foot and toes. If the above symptoms occur, you should go to the orthopedic department of the hospital to take an X-ray of the lumbar region to understand the stability of the lumbar spine and the osteophytes or osteoporosis; make an MRI of the lumbar spine to understand the severity of the lumbar spinal stenosis, and if necessary, make an electromyography of the lower limbs to exclude neurogenic diseases. For patients with mild lumbar spinal stenosis (walking more than 1 km, occasional appearance of the above symptoms, disappearance of symptoms after good rest), conservative treatment or observation is possible; for patients with moderate or severe stenosis (moderate walking less than 500 m, severe walking less than 100 m), generally speaking, conservative treatment is not effective and surgical treatment is required, which involves expanding and decompressing the narrowed spinal canal and nerve root canal. At the same time, bone grafting is performed to stabilize the unstable lumbar segments. Some patients are afraid of lumbar spine surgery, fearing paralysis after surgery. In fact, modern orthopedic surgery is developing rapidly, especially in spine surgery: the hardware of operating rooms in tertiary hospitals is comparable to that of top international hospitals, the application of high-quality electric knives, clear C-arm fluoroscopy and advanced orthopedic instruments lay the foundation for successful surgery, and multi-level academic exchanges and specialized training of doctors have greatly improved the level and quality of surgery. Generally speaking, the satisfaction of surgery should reach 90% or more, and the chance of accidents and paralysis is very low! Of course, patients should choose the hospital and the right doctor!
