What is kyphosis?

Kyphosis refers specifically to an abnormal convex outward curvature of the upper spine, typically in the thoracic region. This condition results in a rounded or hunched back appearance and can occur due to various factors such as age-related degeneration, osteoporosis, or developmental issues. A normal spinal alignment would not involve such a prominent outward curve in the upper spine, and conditions affecting the lower back would relate to a different form of curvature known as lordosis. Additionally, while kyphosis may result from or lead to injuries over time, it is primarily classified as a postural abnormality rather than a type of spinal injury itself. Thus, understanding kyphosis as involving the upper spine's curvature provides clarity on how it affects overall posture and spinal health.
