Uses single-photon absorptiometry in determining whether measurement of bone density predicts hip fracture in women. Inverse correlation between bone density in appendicular skeleton and risk of hip fracture; Age-related increase in risk of hip fracture among older women; Incidence of hip fracture by age-adjusted quartile of bone mineral density; Causes of hip fracture.
