@francine498 we presume you’re in pain as the reason for your surgery? My scoliosis is 20-22 degrees lumbar and thoracic curves which do not cause me much issue. I had a fusion in 1988 for spondylolisthesis grade II after a fall from an earthquake. I don’t need additional surgery at this point (74 y.o.) and hope I will not need it in the future.
