Vertebral fracture assessment using standard bone densitometry equipment predicts incident fractures in women.
Vertebral fractures are the most common fracture among the elderly, have a detrimental effect on patients' quality of life, and increase the risk of future fractures. Yet, two-thirds of vertebral fractures remain undiagnosed; therefore, improved detection methods are needed. In this Practice Point commentary, we discuss the study by McCloskey et al., in which low radiation dose imaging with a bone densitometer was used for vertebral fracture assessment (VFA) in a prospective cohort of elderly women. Participants were enrolled in a randomized, double-blind, placebo-controlled trial of the oral bisphosphonate clodronate. Prevalent vertebral fractures detected by VFA were associated with an elevated risk of subsequent osteoporotic fractures, including hip fractures. This finding remained significant after adjustment for age, weight and treatment effect, and in a few instances even after adjustment for femoral BMD. Here, we highlight the importance of identifying vertebral fractures, and the potentially substantial role of VFA in the clinical evaluation and management of patients suspected to have osteoporosis.
