Hey, Tree:

Ooooh you hit a sore point.

Yes, from my photos, I have bridging activity at S1/L5--I think we all have this from lumbago--IT IS ALL related to AS; NOT because we are getting old! Well, AS is like progeria of the spine...

L1/L2 was the location of my previous surgery to add Harrington rods so that it would heal, but my trip down the stairs apparently undid all that, and I have severe pains there again. I blame S1/L5 for not being flexible enough, causing L2 to let go with a pseudarthrosis (fracture) or break clear through--that was PAINFUL!

Happy Water Skiing,
John
