So Sarah has always had some degree of kyphosis(hunching forward). She also has a curve where the spine twists on itself, like a corkscrew. Neither condition lends itself to surgery, unless really severe. She has had both of these conditions since she was a baby.
At her last x ray, her kyphosis measured at 94 degrees, which would be terrible news if her spine was fixed at that curve.But, it is flexible, meaning it bends and unbends, somewhat.
There are two instances when Sarah's spine straightens as best it can. One is when she is in the stander and the other is when she sleeps on her stomach. So, I snuck in this afternoon when she was taking a nap and snapped a couple of photos.
Here her head is to the right. You can see a little curve. What you now see is fixed. It is as straight as it will go.
In this pic her head is to the left. Same curve, opposite side view. Not TOO bad.
