Kyphosis is a spinal disorder in which an excessive outward curve of the spine results in an abnormal rounding of the upper back. The condition is sometimes known as "roundback" or—in the case of a severe curve—as "hunchback." Kyphosis can occur at any age, but is common during adolescence. Kyphosis is an exaggerated, forward rounding of the back. It can occur at any age but is most common in older women. Age-related kyphosis is often due to weakness in the spinal bones that causes them to compress or crack. Other types of kyphosis can appear in infants or teens due to malformation of the spine or wedging of the spinal bones over time. Mild kyphosis causes few problems. Severe kyphosis can cause pain and be disfiguring. Treatment for kyphosis depends on your age, and the cause and effects of the curvature. Mild kyphosis may produce no noticeable signs or symptoms. But some people experience back pain and stiffness in addition to an abnormally curved spine.

Kyphosis, also known as roundback or hunchback, is a condition in which the spine in the upper back has an excessive curvature.  The upper back, or thoracic region of the spine, has a natural slight curve. The spine naturally curves in the neck, upper back, and lower back to help absorb shock and support the weight of the head. Kyphosis occurs when this natural arch is larger than normal. If someone have kyphosis, you may have a visible hump on your upper back. From the side, your upper back may be noticeably rounded or protruding. In addition, people with kyphosis appear to be slouching and have noticeable rounding of the shoulders. Kyphosis can lead to excess pressure on the spine, causing pain. It may also lead to breathing difficulties due to pressure put on the lungs. Kyphosis in older women is known as dowager’s hump.
