Stone, thing is i went to see them in person in NY.
Illerhaus and Biersdadt barely talked and Peterson did all the talking.
My question here is i have 2 well known doctors with 2 different surgical recommendations.
Biersdadt through Malte Peterson says 3 level
Clavel says hybrid fusion/ADR due to my steep sacral slope and leave L3-L4.
I would of course contact Dr. B again before considering the actual surgery.
I also came across a nice article about a steep sacral slope
