I'm sorry Shak:
I have no experience with this. I'm still trying to figure out what all the Letters stand for

...I've seen
PLIF and now
ALIF... I know Anterior and Posterior and I'm guessing the "L" is lumbar and "F" is fusion, but have no clue as to the "I".
No help from me,

I only had a discectomy,
but do want to tell you that you will be in my thoughts and prayers......and good luck to you on getting your answer...There are wonderful folks on this board....I'm sure your answer will be comming soon.
Happy Holidays!
Bg
