Osteoporosis: impact on the elderly societal concerns, and the role of radiology.
Osteoporosis has recently become a concern in both the medical and lay communities. Osteoporosis may be defined as a decrease in bone mass with maintenance of normal bone composition. The increase in bone fragility results in an increased incidence of fractures. The disease most commonly affects postmenopausal women, particularly Caucasians. It is estimated that 1.2 million fractures per year can be attributed to osteoporosis. These fractures cost the health care system approximately $18.1 billion per year. Given the magnitude of the health and attendant financial problems, osteoporosis deserves the attention of clinicians and researchers. This article will deal with the pathophysiologic processes, techniques for bone mineral determination, therapeutic regimens and the advisability of mass screening. The relationship between bone mineral content and fracture risk has not been clearly defined. If every American woman between the ages of 40 and 54 years were given a single bone mineral screening examination, the cost would be approximately $187.5 million/year. At this price and in the absence of accepted treatment programs, it does not seem prudent for radiologists or other physicians to recommend expensive mass screening.
