What term describes the outward curvature of the thoracic spine?

The term that accurately describes the outward curvature of the thoracic spine is kyphosis. This condition is characterized by an exaggerated, forward rounding of the back, which typically occurs in the upper spine. While everyone has a natural curve in the thoracic region, individuals with kyphosis exhibit a more pronounced curve that can lead to a hunched posture.

Kyphosis can result from various factors, including age-related degeneration, poor posture, or conditions such as Scheuermann’s disease. It is essential to distinguish kyphosis from other spinal curvature issues; for instance, scoliosis refers to a lateral curvature of the spine, while lordosis pertains specifically to an inward curvature of the lower back. Flattening is not a widely used term in spinal anatomy and does not accurately describe any specific purposeful curvature or condition of the spine. Thus, kyphosis is the correct term for the outward curvature in the thoracic region.
