I believe patients can be very confused about spinal injections. There are several types that can be safe and very effective to treat back pain as well as leg pain from stenosis or arthritis of the facet joints in either neck or lower back. I usually attempt less invasive medial branch block and facet steroids for senior patient that have pain with standing extention associated with leg pain. If a patient only has leg pain , then a transforaminal nerve block is all that is required. Not all injections are the same and precision is very important. I feel succcess is high and surgery in less then 5 percent.
