After undergoing a life-changing surgery, a woman who had a 180-degree spine fold can now stand upright once more

People with scoliosis have a side-to-side curve in the spine that can look like an "S" or a "C."

The spine is sometimes called "the backbone," but it's not just one bone. It's made of lots of bones (called vertebrae) that are connected by a type of elastic tissue called cartilage. This gives people the flexibility to bend, stretch, balance, and even walk.

Scoliosis is when the vertebrae form a curved line instead of being straight. Sometimes they also rotate (twist), like a corkscrew.
