We are the same in some areas. I had my Harrington rods put in when I was 14. I had a 62° curve which they got down to 35°. I continued with lumbar issues. In 1989 after 6 surgeries, they completed a 2 part surgery and and then I was fused T2-S1 and screwed into each side in the pelvic bone (3 screws each side). I really did not have any issues until 2018. My cervical had developed degenerative issues. They did ACDF C3-C7. I was still having cervical pain and they related it to flat back. In 4/2021 I had a lumbar osteotomy to correct my sagittal balance. They did not fuse my si joints at that time and I believe they should have. The SI joints were fused 2/2022 and 4/2022. I still had cervical pain and si joint pain. At this time I researched several doctors, I received 3 opinions. In my cervical, C3-5 did not fuse and also my SI joints and fractured screws in my lumbar. In 3/2023, I had a neurosurgeon whom did a posterior fusion C3-5. This has helped tremendously with my cervical. In April I had a call from Mayo Clinic that the accepted my complex cases. I am now working with a group of doctors with my SI joints and degenerative hips. I am 5 weeks post op with my right hip and going well. I have left hip replacement schedule for 11/16 and then revision on si joints. Long process bit feel really good about direction. Let me know when you want to chat.
