Which type of spinal curvature leads to a hunched posture?

Kyphosis is the type of spinal curvature that leads to a hunched posture. This condition is characterized by an excessive outward curvature of the thoracic spine, which can create a rounded or hunchback appearance. In kyphosis, the vertebrae in the upper back become more angled than normal, which causes the back to round forward. This can result from various factors, including developmental issues, degenerative diseases, osteoporosis, or poor posture over time.

Understanding kyphosis is essential for recognizing its implications on posture and overall spinal health. In contrast, lordosis refers to an excessive inward curvature of the lumbar spine, typically resulting in a swayback posture. Scoliosis involves a lateral curvature of the spine, which does not typically manifest as a hunched posture but rather gives a "C" or "S" shape to the spine. Normal alignment denotes a typical spinal curvature where none of these abnormalities exist. Each of these conditions affects posture differently, but kyphosis is specifically associated with the hunched appearance.
