Lumbar spinal stenosis is generally a single-segment lumbar spinal stenosis or a relatively small degree of stenosis suitable for minimally invasive surgery. 1. Lumbar spinal stenosis refers to congenital or acquired factors that lead to narrowing of the lumbar spinal canal and intervertebral foramina, which in turn causes compression of the lumbar spinal nerve tissues, impaired blood circulation, and lumbar pain and leg pain, etc. If the lumbar spinal stenosis of a single segment or the range of stenosis is relatively small, the nerve compression is not too serious, and the situation is relatively minor, then it is suitable to do minimally invasive surgery. 2. Lumbar spinal stenosis usually occurs in middle-aged and old people, in life, we should eat a light diet, eat a balanced diet, eat more fruits and vegetables, meat and so on. Exercise appropriately and correct bad posture in time. 3. If the lumbar spinal stenosis is multi-segment and the condition is serious, open surgery may be needed for decompression and internal fixation. It is recommended that the patient go to the hospital in time, do not delay the condition.
