Spinal stenosis surgery is relatively major surgery. Spinal stenosis is a condition in which the diameter of the spinal canal narrows for a variety of reasons, causing pressure on the structures within the canal. Severe spinal stenosis requires prompt surgical treatment to enlarge the diameter of the spinal canal and relieve pressure on the structures within the spinal canal. This is a relatively large operation, and in the case of multisegmental stenosis, posterior decompression of the laminae is required to remove the posterior laminae and enlarge the diameter of the spinal canal, as well as fixation with a nail-rod system and fusion of the intervertebral implants. The surgery is relatively long and there is a lot of bleeding. Recovery time is also relatively long. Most spinal stenosis surgeries are major operations. If surgery is needed, please go to a regular hospital and standardize the treatment under the doctor’s guidance to avoid delays.
