Which curve pattern is most commonly seen in juvenile idiopathic scoliosis?

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

Answer: (A)

The main idea is that the typical initial pattern in juvenile idiopathic scoliosis is a thoracic curve bending to the right. In this age group, a right-sided thoracic deviation is by far the most commonly seen primary deformity, often with a compensatory curve elsewhere (like a small left lumbar curve) to balance the spine. This right thoracic pattern reflects the usual tendency of AIS to favor a rightward thoracic curvature during adolescence. Left thoracic deviations are much less common as the primary curve, and curves in the cervical region or thoracolumbar region as the main deformity are seen far less often. Thus, a right thoracic deviation best fits the common presentation.
