Jay, You know I picked Rod Stewart as a user name because someone had already picked Jose Cuervo.....It's important to have a good username, I think it helps with healing. (smiley face)
Harrington rods came around 1960....and yes it is amazing to see what is possible when dealing with spinal deformity. Some of the rare cases like yours are cases of orthopedic ingenuity at its finest. Amazing pieces of art work of the spine, that are not to be forgotten....I would bet your surgeon is proud, what was his name again? You should post those side view x-rays of yours once again, its amazing I remember these things.
And of course, before I forget, its nice to reflect on how truly lucky we are.....to have that second chance is a blessing as the pain of deformity can come in like a powerful storm. Kyphosis is a wicked sort of thing, here is a link with incredible progression rates, and also informative info on strut grafting. Do stay in touch!
