What curvature of the spine is typically referred to as a "hunchback"?

Kyphosis is the term used to describe an abnormal forward curvature of the spine, often referred to colloquially as a "hunchback." This condition typically occurs in the thoracic region of the spine, leading to a rounded appearance of the upper back. In kyphosis, the thoracic vertebrae may become wedged or compressed, which contributes to an exaggerated curved posture. This condition can be due to various factors including age-related changes, developmental conditions, or diseases affecting the spine.

In contrast, lordosis refers to an exaggerated inward curvature of the lower back, while scoliosis involves a sideways curvature of the spine. A neutral spine describes a healthy alignment of the spine without abnormal curvature. These other terms highlight distinct types of spinal alignment issues, making kyphosis the specific condition that correlates with the "hunchback" description.
