There are many causes of scoliosis, but AIS is the most common.

Scoliosis is a medical term taken from a Greek word meaning curvature. This disorder may develop during childhood, and it causes the spine to curve to the left or right side.

Children with scoliosis and their parents have a lot of questions about the condition. In this series of four articles, orthopaedic surgeons from the American Academy of Orthopaedic Surgeons and the Scoliosis Research Society answer some of the questions they most commonly hear from patients and their parents.

The sacroiliac (SI) joint can be a source of back pain for many patients. The joint is composed of the sacrum (bottom portion of the spine) and the iliac crest (part of your pelvis).

Costal chondritis, costochondritis and Tietze syndrome are sometimes used interchangeably and characterized by inflammation of the part of the rib that is cartilage.

Spina bifida is a neural tube defect resulting in mild to severe disabilities, depending on where the unprotected portion of the spinal cord is and how much is exposed.

Spinal fractures occur when an injury is sustained to the spine resulting in a break or disruption of the spinal vertebrae or the attached ligaments.

Spondylolisthesis commonly occurs in the lower back, which bears more weight and frequently experiences more twisting.

Spondylolisthesis occurs when one vertebra slips forward over the vertebra below it.

The spine is made up of a series of connected bones called "vertebrae." In about 5% of the adult population, there is a developmental crack in one of the vertebrae, usually at the point at which the lower (lumbar) part of the spine joins the tailbone (sacrum).
