Which term describes exaggeration of the thoracic curvature, often referred to as hunchback?

• A. exaggerated lumbar curvature (lordosis)
• B. lateral curvature of the spine (scoliosis)
• C. normal thoracic curvature
• D. exaggerated thoracic curvature (hunchback)

Answer: (D)

Exaggerated curvature of the thoracic spine is hyperkyphosis, often referred to as a hunchback. The thoracic region normally has a backward (kyphotic) curve, and when that curve becomes more pronounced, we describe it as hyperkyphosis. The choice that states an exaggerated thoracic curvature and uses the term hunchback directly matches this description. In contrast, exaggerated lumbar curvature describes lordosis, a lateral curvature describes scoliosis, and a normal thoracic curvature isn’t the abnormal condition. So this option is the best because it precisely identifies the abnormal thoracic curvature and its common name.
