Which statement describes the difference in typical thoracic curve patterns between infantile and juvenile idiopathic scoliosis?

• A. Infantile is right thoracic; juvenile is left thoracic
• B. Infantile is right thoracic; juvenile is right thoracic
• C. Infantile is left thoracic; juvenile is right thoracic
• D. Infantile is left thoracic; juvenile is left thoracic

Answer: (C)

Infantile idiopathic scoliosis most often presents with a left thoracic curve, while juvenile idiopathic scoliosis more commonly shows a right thoracic curve. This reflects how scoliosis tends to behave differently across early life and later childhood, influencing progression risk and management decisions. So describing the typical difference as infantile left thoracic and juvenile right thoracic aligns with observed patterns.
