Lenke classification of scoliosis

Classification

Type 1

• Main thoracic: Main thoracic curve is the major curve; proximal thoracic and thoracolumbar/lumbar curves are minor nonstructural curves

Type 2

• Double thoracic: Main thoracic curve is the major curve; proximal thoracic curve is minor and structural; thoracolumbar/lumbar curve is minor and nonstructural

Type 3

• Double major: Main thoracic and thoracolumbar/lumbar curves are structural; proximal thoracic curve is nonstructural
• Main thoracic curve is the major curve and is greater than, equal to, or no more than 5 degrees less than the Cobb measurement of the thoracolumbar/lumbar curve

Type 4

• Triple major: Proximal thoracic, main thoracic, and thoracolumbar/lumbar curves are structural; either of the two latter curves may be the major curve

Type 5

• Thoracolumbar/lumbar: Thoracolumbar/lumbar curve is the major curve and is structural; proximal thoracic and main thoracic curves are nonstructural

Type 6

• Thoracolumbar/lumbar-main thoracic: Thoracolumbar/lumbar curve is the major curve and measures at least 5 degrees more than the main thoracic curve, which is structural; proximal thoracic curve is nonstructural
