What curve pattern predominates in infantile idiopathic scoliosis?

• A. Right thoracic deviation
• B. Left thoracic deviation
• C. Thoracolumbar deviation
• D. Cervical deviation

Answer: (B)

Infantile idiopathic scoliosis most commonly presents as a single thoracic curve that bends to the left in early childhood. This left thoracic deviation is a characteristic pattern for IIS and helps distinguish it from other ages, where right-sided thoracic curves are more typical. Many of these curves are mild and have a good chance of improving as the child grows, so initial management is often just observation. If the curve progresses or is more severe, bracing or surgical options may be considered.
