Study Notes

Lenke Classification System

  • Comprises three components: curve type, lumbar spine modifier, sagittal thoracic modifier.

Scoliosis Curve Types

  • Type 1: Characterized by a single, structural main thoracic curve.
  • Type 2: Features double thoracic curves, consisting of proximal and main thoracic structural curves.
  • Type 3: Known as double major; includes both a major main thoracic curve and thoracolumbar/lumbar structural curves.
  • Type 4: Identified as triple major; involves structural curves in all three areas (thoracic, thoracolumbar, lumbar).
  • Type 5: Reflects a single thoracolumbar/lumbar structural curve.
  • Type 6: Includes a double curve with a major thoracolumbar/lumbar curve and a main thoracic curve.

Major Curves in Scoliosis Types

  • Types 1-4: The thoracic curve serves as the major curve.
  • Types 5-6: The thoracolumbar/lumbar curve is the primary curve.

Scoliosis Causes

  • Idiopathic: Refers to an unknown cause of scoliosis.
  • Congenital: Resulting from conditions such as spina bifida.
  • Neuropathic: Associated with conditions like cerebral palsy.
  • Myopathic: Related to muscular dystrophy (DMD).
  • Traumatic: Often a result of motor vehicle accidents (MVA).
