I am 35 years old and have led a pretty rigorous life as far as sports and recreation goes and I have several young children, for all these reasons I plan on living a go-go life for the foreseeable future. However, my C-4 and C-5 never separated and my C-3 is severely arthritic and covered in spurs and my C-4/C-3 disc is degenerated leading to chronic and at times totally debilitating pain. My orthopedist recommends fusion of my C-3 to my C-4/C-5 block of bone. I am confident this will solve my chronic pain but given my age and activity level I am worried about how this will affect my quality of life and the long-term health of my adjacent discs. I am intrigued by the total disc replacement option, but my doctor thus far has not informed me about it, I was hoping I could get some advice from the "school of life" experts on this forum. I am curious if I am even a candidate for it given my current, albeit involuntary, fusion.
