Osteoporosis
Osteoporosis is a metabolic disorder associated with decrease in the mass of bone. By far, most of the instances of osteoporosis seen by the Social Security Administration are in post-menopausal women. Osteoporosis may be confined to the spine, but other bones may be involved in those who have used corticosteroids. A collapse of vertebral bodies, especially in the upper back, is known as a compression fracture. Compression fractures are visible on plain X-ray or other imaging studies. If the fracture involves the anterior (front) part of a vertebral body more than the rest of the vertebra, the spine will tend to curve forward and result in the popularly known dowager’s hump.
Compression fractures are graded in regard to the percent of the vertebra that is compressed, compared to the normal height of the vertebra. Normal height is judged from adjacent vertebrae. Pain, loss of motion, and muscle spasm are most likely to be present at the time of fracture and in the healing period. Marked or multiple compression fractures are more likely to produce chronic pain.
Plain X-rays are much less sensitive than bone densitometry in determining the severity of osteoporosis. A normal appearance of bone on plain X-rays only rules out the most advanced osteoporosis. Plain X-rays are fine for determining the percentage of vertebral body collapse in compression fractures.
