Greetings from Berlin.  It's almost 3am and I need some sleep.  Thursday was day 3 of 4 of the Spine Arthroplasty Society's 7th annual congress.  (My fifth.)  It's been an incredible road that brought me here.  I'm trying to blog the concress, but struggling to keep up. 
Today, I attended a celebration of 22 years of Charite' artificial disc replacements.  
I was honored to meet the very first ADR recipient... implanted with a VERY early version of the Charite in 1984!
Read about it on the blog linked on the GPN site or go directly there by

I wish I could write more now... gotta sleep!

PS... I'll catch up on posts and email this weekend... SAS is non-stop, if I blink, I miss something important.
