Hi Don...
Welcome to the group. I encourage you to read some of the threads in this forum (Revision). There are a lot of people who had surgery when they were young, and who needed to have revision surgery as adults. Though I don't remember their user names, there are even a few people like yourself, who had their original surgery without implants.
My advice at this point would be to get yourself in a position of being fully insured. Once that's accomplished, you should try to find a specialist who has a lot of experience in treating patients with prior fusions. You can find a list of specialists here:

If you can't find anyone in PA, it appears that you're not too far from NYC, where there are an abundance of really good surgeons.
Best of luck with your journey.
Regards,
Linda
