Which statement describes the thoracic curvature?

• A. Concave anteriorly from T2 to T12.
• B. Convex anteriorly from T2 to T12.
• C. Concave posteriorly from T2 to T12.
• D. Flat curvature throughout the thoracic spine.

Answer: (A)

The thoracic spine displays a kyphotic curve, which means it bends backward when viewed from the side. This shape makes the anterior surface form a concave contour while the posterior surface is convex. So describing the curvature as concave anteriorly from T2 to T12 accurately captures the thoracic kyphosis. Descriptions that imply the curve bows toward the front (convex anteriorly), or that it’s flat, don’t fit the normal thoracic alignment in this region.
