I'm new here and found this thread. I'm facing pedicle subtraction osteotomy. I've been fused from S1-L3 since 1999. The thoracic portion of my back has developed kyphosis, don't know the degrees, I have degenerative bone disease and stress fractures. I'm 70 years old. I want the surgery to help straighten me up. I can't breathe while walking, my neck is suffering because of having to bend it to look where I'm going. The surgeon I'm seeing gives me confidence in his decision and ability. I looking for insight about what I'm facing with this new surgery. He will be putting in the screws and a cage. He will fuse S1 to L1, after removing the 20 year old hardware. Then use a cage from there to T3, I think he said. He also said, "you won't like this but I'm going to put screws in your pelvis to stabilize everything". What has been some of your experiences with this massive surgery? Recovery time, to at least manageable pain? What will my body move like afterwards? Do you bend again? I bend now from my waist with no problems. Any answers will be helpful. I don't have a date yet, waiting on insurance approval. Thank you!
