Appreciate all of the replies to my earlier thread and now have some progress to report as well as new questions. Now I have talked to 3 different surgeons and even though they all agree on fixing my flat back, they really vary in their approaches and this is confusing to me.

One wants to piggy-back new instrumentation on my Harrington rod. Another wants to do an ALIF, but not do anything with the old rod. The third surgeon wants to also do an ALIF, but also take out all of the old hardware in the process. I have no issues with the old rod. Does anyone know any advantages to removing the old rod, especially if it hasn't caused any problems?

Would really appreciate any advice I could get on any of this.

Thanks all!
