Explanation

When a person's spine curves to the side, he or she has a medical condition called scoliosis. A human spine, or backbone, is usually straight; when it curves in an S or C shape, it's often because of scoliosis. When a patient is diagnosed with scoliosis, he or she receives physical therapy and sometimes needs to wear a brace that helps to gradually straighten the spine. The Greek word skoliosis literally means "crookedness," from the root skolios, "bent or crooked."
