The spine is normally straight, consisting of 33 small, individual bones stacked on top of one other with a disc of cartilage between each. The spine is the main support for the body, allowing you to bend over, stand upright, and twist from side to side.
With scoliosis and other spinal deformities, the spine becomes curved or twisted and can cause uneven shoulders, breathing difficulties, back pain, and a humpback or swayback appearance. If left untreated, these conditions can get worse over time.
