I have a bone disease that causes my bones not to get enough blood flow that’s why mine did not take. My bones start to crumble. The neurosurgeon that specializes with people that have bone diseases like mine should have a laminectomy.
Mine is C6-7. A PA (physical assist) that’s a friend of mine has had to have his repeated. He has had three. Just like hips they get loose and have to be replaced again. You are moving your neck so you get wear and tear on the surgery.
How long does ACDF surgery last?

ACDF surgery is permanent. While rare, you may need additional surgeries to treat arthritis or weakening vertebrae near the initial surgical site (adjacent-level degeneration). Many studies report that ACDF surgery results last for more than 10 years before possibly needing additional surgeries.
That’s from the Cleveland clinic.
