A spine deformity is a problem with curvature and rotation of the spine.
- Scoliosis is a condition that makes the spine curve sideways, like the letter “S” or “C.” Often, the spine also twists so the back is not flat. If the spine twists, one side of the back sticks out more than the other
- Lordosis is an inward, or increased curvature of the spine, commonly called "swayback."
- Kyphosis is the term doctors use to describe a curving of the upper back. The upper part of the spine curves more than normal, causing a rounded or hunched back.
