A mathematical formula has been developed that can predict a woman's risk of osteoporotic fracture.
The formula has proven accurate 75 percent of the time, and it could allow physicians to tailor treatment strategies. The equation takes into account likelihood of falling, bone mass, body weight and other factors.
To develop the formula, more than 200 elderly women who had sustained a low-trauma fracture during a two-year period were examined, as well as more than 400 elderly women who had not sustained a fracture during that period.
The formula was then tested on a random third group over a six-year period. The formula successfully predicted 75 percent of fractures within two years of the study's start.
Women with osteoporosis have bones that are less dense and more likely to break, as a result of larger pores in the bone, reduced calcium levels and fewer blood vessels.
