1. Scoliosis Curves

2. thoracolumbar Is longer than most and extends from the upper to the lower spine. It may curve either to the right or the left. Small curves above and below accompany this long curve. Although thoracolumbar curves usually cause minor deformities, they can result in severe rib and trunk distortion. This curve is uncommon.

3. thoracic curve The thoracic curve is one of the most common scoliotic curves. It affects the upper spine and usually curves to the right side of the body. The vertebrae experience severe rotation with this curve, which results in rib abnormalities and very rarely, cardiopulmonary dysfunction. A right thoracic curve is usually accompanied by smaller curves both above and below the largest curve.

4. Lumbar The lumbar major curve effects the lower part of the spine and often curves to the left. This curve remains fairly flexible, but can stiffen with age and develop arthritis. A lumbar curve does not often cause serious deformity

5. Double Major The double major curve is difficult to identify as it causes only minor visual distortion. A double major curve is made up of two curves with nearly equal angles. One curve usually occurs on the upper spine, and the other on the lower spine. A thoracic curve typically curves to the right and the lumbar to the left. A shortened trunk (length from shoulders to hips) is commonly seen with this curve.
