Four Main Curve Patterns: Scoliosis

For many years, a common shorthand description of scoliosis curves was to refer to a “C” or “S” curve. However, this designation may be considered outdated among some sources. In addition, we found some variation among sources in how curves are described.

Thoracic

• Focused in the thoracic (mid-back) region
• 90% curve to the right (dextroscoliosis)
• Possible smaller counter curve in the lumbar region

Lumbar

• Focused in the lumbar or low back region
• 70% curve to the left (levoscoliosis)
• Possible smaller counter curve in the thoracic region

Thoraco–Lumbar

• Major curve in both thoracic and lumbar region
• 80% curve to the right (dextroscoliosis)

Combined / Double / S-Curve

• Main curve in the thoracic region
• 90% curve to the right (dextroscoliosis)
• Equal counter curve in the lumbar region
