Am I making the correct choice?

Hi Richard
I definitely agree with everyone thats said see someone who can offer both options - fusion and ADR.
Fusion at 5/S1 and ADR at 4/5 might well provide the cushion to stop the 2 levels above deteriorating further.
Where are you in the UK? There are good surgeons in the UK who can offer both options but possibly not in your location. Are you limited to NHS or could you go private? See a couple more surgeons privately to get opinions - you don't have to proceed to surgery and can always switch back to NHS..
If you need help with surgeons i might be able to help.. Try visiting the UK ADR site where you'll find details of UK doctors..
Wishing you all the best
Tim
