I can see where your coming from because Esme's back does cosmetically look quite okay. Elysia didn't have the Lumbar curve that Esme had and she had much more of a tilt on her than Esme has. I think I'm correct in saying that for Esme the reason is that she has an S curve - Thoracic 62 and Lumbar 63 - wasn't that one of the measurements they gave you? So that means that her trunk is bending one way and then again the other.
After she has surgery you will definately see some major height changes for her. Scoli x-rays look very scary - you can't always see the real internal drama that's going on from the outside. Have a read of our blog, Elysia's before and after x-rays are on there. I'll try and put up a picture later of her back before surgery on there as well - there's one of her hump if you scroll down through the older posts.
