According to recent information from the National Osteoporosis Foundation1 and the Office of the Surgeon General2, osteoporosis is a major medical problem. The disease currently affects 8 million women and 2 million men in the United States. An additional 34 million Americans have low bone mass. Each year, an estimated 1.5 million individuals in the United States experience a fragility fracture secondary to osteoporosis, resulting in an annual cost of 18 billion dollars. With the rapidly aging U.S. population, the problem of osteoporosis is now reaching epidemic proportions. There are 75 million baby boomers entering the stage in their lives when they are most at risk for osteoporosis. One-half of all women and one-third of all men will sustain a fragility fracture during their lifetime.
