Poor chap!
I had an unstable fracture of C6 vertibrate when I hit a tree on my GSXR 2 years ago. For 3 weeks I couldnt move below the shoulders but it slowly came back. Now I only have nerve damage to the inside of my arms.
They fixed me by inserting and bolting a Ti plate on to the inside of my spine which fixed C7,C6 and C5 into a rigid structure.
I do hope they can fix him.
Simon.
