@bonnie111 Hello and welcome to Connect. I know it’s a tough choice when you don’t really understand what you’ve been offered for surgery. Autograft and Allograft refer to where the bone comes from to replace the space after a disc is removed. One is donor or bone bank bone which is the hard mineral matrix that all bone cells have been removed from. The other is your bone that a surgeon removes from your hip and carves to put it into your spine. It comes with living bone cells in it, but also can leave your hip with pain the rest of your life. It is best to get other opinions from good spine surgeons which will help you decide. On Connect, there is a search bar at the top where you can type keywords and find other discussions and posts from other members. My experience is that I had a fusion of C5/C6 at Mayo done without hardware and with donor bone. I stayed in a Neck brace until fused for 3 months.
