Vertebroplasty Diagnosis

Osteoporosis is called a "silent disease," because bone loss occurs without symptoms. People may not know they have osteoporosis until their bones become so weak that a simple strain, twist of the body, bump or fall causes a bone fracture. Fractures may occur in the hip, wrist, ribs or elsewhere, but the most common site of fracture is in the vertebrae, the bones that make up the spinal column.

There are 10 million people in the U.S. who suffer from osteoporosis and another 28 million with thinning bones that put them at risk for fractures. 80 percent of those affected are women. Also at risk are those whose bones have become fragile due to the long-term use of steroids to treat a variety of diseases such as lupus, asthma and rheumatoid arthritis. Significant risk has been reported in all ethnic groups, and while osteoporosis is most common in old age, it can occur at any time.

Among individuals with osteoporosis, there will be 700,000 painful spinal fractures each year. These so-called "compression" fractures are caused when the weakened vertebrae of the spine collapse usually in the middle (thoracic) or lower (lumbar) spine. A collapsed vertebra may initially be felt as severe back pain. When more than one vertebra collapses, loss of height or spinal deformities such as kyphosis ("widow's hump") or stooped posture may result. In some cases, the fracture stabilizes on its own, and the pain goes away. But for many, the pain persists because the crushed bone continues to move and break.
