This is so helpful. I was in car accident on July 3, 2020 and broke my back from T12-L2. I currently have 2 rods and 10 screws. One of my top screws is currently loose and my doctor recommended to remove all my hardware. I was a little frightened when she told me that. I didn’t even know it could be done. So thank you for answering some of my questions. God Bless you🙏🏼
