Anterior Cervicl Fusion with screws : I have a serve compression C3-c4, C4 to C5 OK, but C5-c6 about 50% damaged right side. My docotr is fusing all three because he indicates, if I don t, I will back in due to stress/pressure between will make thrid fail if he fixes two or just the one. I read up and it indicates eventually c6-c7 will go, maybe c2-c3 due to stress of multi fusion. What is best? It seems I loose either way and would think one fusion would be less stressful to the rest.. Thank you
