Hi Mark,
I'm sorry, I tried that phone number several times, and I guess they have either changed it or moved
I saw Andrew Kam at Westmead Private Hospital for a consult several years ago. He was a very professional easy person to talk to and was not one to push you into surgery - in fact he said to wait as long as possible in my case.
I was just reading his web site and it says he prefers to "focus on complex spinal issues" - whether the removal of an ADR would be in that category, I don't know, but I would certainly consider contacting him. He certainly has a good reputation as far as other professionals are concerned.
Here is the link with his details.
