I had a spinal decompression performed on 3 ruptured disks, L3-4 L4-5 and S1. After sufuring for 20 years I am completely pain free. Before surgery I consulted with two top surgeons. One surgeon wanted to fuse all 3 levels for spinal stability. The other surgeon who happens to be an authority for ortopedic surgery in the United States told me absolutely I did not need fusions that fusions are old school and are only necessary in certain circumstances. The goal was to relief the pain that radiated down both legs and my right foot had no movement. The procedure was to remove bone from the compressed nerves caused by the ruptured disk. The disk where left alone. When I awoke from the surgery my right foot movement returned and all the pain was gone. To provide the necessary stability in the spine the muscels are being exercised which will stabilize the spine. This type of surgery has a far greater chance of success than fusions. I would recommend to anyone that is considering lumbar surgery to first try the less invassive approach and should that fail fusion is still an option. I should mention that spinal fusions cause unfused joints to carry the load and in time they will fail. By the way I had my surgery in Rancho Mirage Eisenhour Medical Spine Center and I am so happy with the results.
