Hi there fellow Washingtonian! I troll the forum occasionally now having had my original surgery in 2013 and a few revisions since then. I am 73 and live in Yacolt, WA about 45 minutes north of Portland Oregon. My revisions were done by Dr. Robert Hart, previously in Portland but now at Swedish Hospital in Seattle. He only does spinal deformity surgery. Sounds like you already have your second opinion set up in Richland, but I wanted to throw Dr. Hart's name out in case you want another opinion.
Best of luck of your decision making. I am fused from T1 to sacrum.
