Welcome,
Your spine history is almost as long as mine. Just wondering how many surgical opinions you've gotten to date? I've had about 7 tho none in the last several years where no doubt there are continuing changes that might have changed what could be offered to me currently.
2000 offered 3 level global fusion
2003 offered 2 level ADR
2006 offered Hybrid surgery with ADR at L4 and fusion at L5S1
Options sometimes depend on timing. Wishing you all the best with your surgical pursuits and hope that whatever you do there will be less pain in your life
