Lumbar spinal stenosis is mostly seen in middle-aged and elderly people and is a common cause of low back and leg pain and weakness in walking in the lower limbs. It is caused by the degeneration of lumbar intervertebral discs, osteophytes and thickening of ligaments as people enter middle and old age, resulting in a smaller space around the nerves and pressure, which causes pain in the lower back and legs and soreness, numbness, weakness and limpness in the lower limbs during walking, while not being able to walk long distances, and in severe cases it is difficult to walk a few dozen meters, and patients often need to squat and rest for a while before they can continue walking, and then still need to squat Rest, able to continue walking a shorter and shorter distance. This is because the space in the lumbar spinal canal becomes smaller when walking upright, which increases the pressure on the nerves and increases nerve ischemia. However, the patient is not affected by cycling and can ride longer distances. The diagnosis of lumbar spinal stenosis can only be established by the physician based on the patient’s symptoms and signs, combined with imaging. The diagnosis cannot be established solely on the basis of the patient’s clinical manifestations or solely on the basis of imaging manifestations. At present, there are many treatment methods. In mild cases, conservative treatment, rest, physical therapy, massage, fumigation, and medication can be used. Many patients can obtain good recent results through epidural closure or sacral canal closure treatment. However, some patients are ineffective through long-term repeated conservative treatment, which affects physical and mental health and has an impact on the quality of daily life. In this regard, surgical treatment should be considered with a view to achieving a cure. The surgical method will be based on the patient’s age, condition, imaging changes, general condition and affordability, etc. After comprehensive consideration, the doctor will agree with the patient to make a reasonable choice.
