The success rate of spinal stenosis surgery is usually 95% or even more. 1. The purpose of spinal stenosis surgery is to relieve the compression of the nerves in the spinal canal. The normal spinal cord or cauda equina nerves travel in the spinal canal, and the nerves only take up part of the space in the spinal canal, and the effusion space is the cerebrospinal fluid and some cushioning space. 2. With the continuous improvement of medical technology and the development of medical equipment, spinal stenosis surgery is now more mature, and the success rate is usually higher. Most spinal stenosis surgeries have a success rate of 95% or more if there is a clear indication for the surgery and if the patient is in good physical condition. After spinal stenosis surgery, you should take plenty of rest, give proper nutritional support, and have regular follow-ups to assess your recovery.
