Thank you. I assume the disc space has collapsed some as the doctor who would do the ACDF said the bone graft would restore height. My fear in fusion is adjacent disc stress and further degeneration. Also I am not sure how lacking the curve in my neck will be impacted by each procedure. My recent injury has lingered for 6 weeks. The burning has subsided but the arm is really weak. I assume my progress will plateau. My neck is very stiff and is now making cracking sounds when I turn my head. Is this something that can be waited out a few more weeks before going under the knife? Disc replacement sounds great but not sure it will last.
