Which term describes an abnormal curvature of the thoracic spine?

The correct term that describes an abnormal curvature of the thoracic spine is kyphosis. This condition is characterized by an exaggerated forward curvature of the upper back, leading to a rounded appearance, often referred to as a "hunchback." In addition to being associated with aging and conditions such as osteoporosis, kyphosis can result from developmental issues or degenerative diseases.

Understanding the specific terms related to spinal curvature is helpful for distinguishing among various conditions. Lordosis refers to an exaggerated inward curve of the lower back, while scoliosis indicates a lateral, or side-to-side, curvature of the spine. Knowing these definitions helps in recognizing how each condition affects posture and spinal alignment differently.
