We went back for another check in. The curve has increased ten degrees in six months, to 60. We've scheduled the surgery for July, after a science camp my teen really wants to attend. There will be about four weeks between surgery and the start of school. The surgeon did not think waiting till July would make any difference in the level of fusion. I can't believe we've gotten to this point but here we are. I guess we just will learn to deal with it. Sigh.
