Came across this article while researching the the length on time it takes for an autograft to heal. Hit close to home for me as I just had spinal fusion 2 months ago and elected to have a graft taken from my hip. Bad choice the pain from the graft is worse than that of the fusion. Didn't know I could have just brought some sps into the operating room Hah!
