Pooling international data to understand long-term bisphosphonate use and atypical femur fractures

Official title: Pooling International Cohort Studies of Long-Term Bisphosphonate Use and Atypical Femur Fractures

Funded at University of California, San Francisco · NIH-11638692 · Data updated 2026-11-12

This project combines large patient datasets from multiple countries to understand how long-term bisphosphonate use relates to rare hip and thigh bone fractures, helping doctors and patients make safer treatment choices.

Who could benefit from this research

Could help

Women who have used bisphosphonates and are at risk for atypical femur fractures, as well as clinicians making treatment decisions for long-term osteoporosis care.

Less likely to help

Individuals without osteoporosis or those not considering bisphosphonate therapy are unlikely to benefit directly.

What this research studies

Researchers will merge individual-level data from three major cohort studies, including radiographically confirmed atypical femur fractures and detailed medication histories, to study how long-term bisphosphonate therapy and drug holidays influence fracture risk. The work will harmonize definitions and use centralized statistical methods to identify which groups of women are more or less at risk. Findings could inform personalized timing of therapy and decisions about starting or pausing bisphosphonates.

Why it matters

Potential benefit: Patients could gain clearer guidance on how long to use bisphosphonates and when to consider drug holidays to minimize fracture risk.

How similar studies have gone: Previous large cohort analyses have shown associations between long-term bisphosphonate use and AFF; this project builds on that approach with harmonized data and deeper subgroups.
