Question
Does oral alendronate reduce new fractures in postmenopausal women with low bone density and a prior vertebral fracture?
Design
Multicentre double-blind placebo-controlled RCT (vertebral fracture arm of the Fracture Intervention Trial).
Patients
Postmenopausal women with low femoral neck BMD and at least one existing vertebral fracture.
Intervention
Oral alendronate daily for about 3 years
Comparison
Placebo
Primary outcome
New morphometric vertebral fracture over about 3 years
Key result
Alendronate roughly halved new radiographic vertebral fractures and also significantly reduced hip and wrist fractures compared with placebo.
Limitations
Population restricted to women with established vertebral fractures; daily dosing used rather than the weekly regimen now standard; limited follow-up for long-term harms.
Impact on practice
Established oral alendronate as the first-line, low-cost treatment for osteoporosis, which remains the default in NOGG and NICE guidance.
