Just a thought, im curious.
Answer:
Depending on how much your spine curves, surgery may straighten your spine a bit and give you back some of your lost height.
To tell how much height you've lost to the curve, pick a spot at the top and bottom of your spine and measure it with a tape. Then run a string from the top to the bottom but follow the curve of your spine. Straighten out the string and measure it. The difference in the two measurements is the height you've lost to your curve.
You won't get it all back, though. How much depends on how flexible you’re. When your scoliosis specialist examines your back, bending left, right, and backwards will give your physician an idea of how much curve can be recovered. If your spine won't straighten out, forcing it to be straight will pinch nerves and possibly paralyze you. So its far superior to correct only as much as your spine can handle.
Answer:
no you won't be, but because they use pins to “straighten” the spine you appear taller.
