Osteoporosis: Predictors of vertebral fracture risk in patients receiving denosumab

Key clinical point: Both total hip bone mineral density (BMD) change and T-score can serve as surrogates for predicting vertebral fracture risk in patients with osteoporosis receiving denosumab treatment.

Major finding: Total hip BMD change and T-score were strong predictors of subsequent vertebral fracture risk, with total hip BMD change accounting for 73% and T-score accounting for 23% of the treatment effect.

Study details: Post hoc analysis of the DIRECT trial involving 1,011 Japanese postmenopausal women and men who were randomly assigned (2:2:1) to receive denosumab, placebo, or alendronate.
