Which term refers to an abnormal thoracic curve of the spine known as "hunchback"?

Scoliosis
Lordosis
Kyphosis
Flatback

The correct answer is: Kyphosis

The term that refers to an abnormal thoracic curve of the spine known as "hunchback" is kyphosis. This condition is characterized by an excessive outward curvature of the thoracic spine, which causes a noticeable rounding of the upper back. Kyphosis can result from various factors, including poor posture, degenerative diseases, or conditions affecting the spine's bones and tissues. In contrast, scoliosis refers to a lateral curvature of the spine, which can occur in a "C" or "S" shape, affecting the alignment of the entire spinal column. Lordosis is described as an excessive inward curve of the lumbar spine, often leading to an exaggerated arch in the lower back region. Flatback refers to a spinal alignment condition where there is a loss of the normal curvature in the lumbar region, which can result in a flattened appearance of the back. Each of these terms describes distinct spinal deformities, making kyphosis the specific term for the "hunchback" condition.
