Compression fractures associated with osteoporosis of vertebral bodies can distort the normal thoracic curvature of the vertebral column in a posterior direction. Such a distortion is called

kyphosis.

Explanation:

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.

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.
