Mechanisms of bone loss after a fracture

Official title: Mechanisms of systemic bone loss following fracture

Funded at University of California, San Francisco · NIH-11386666 · Data updated 2026-11-12

A study at UC San Francisco will look at why bones elsewhere in the body lose mass after a fracture by analyzing blood to find biological clues.

Who could benefit from this research

Could help

Adults with acute fractures (e.g., humerus fracture) who are enrolled in the parent longitudinal study at UCSF.

Less likely to help

Patients not experiencing systemic bone loss after fracture or not participating in blood collection may not benefit from this study.

What this research studies

Patients with a fracture may experience bone loss elsewhere in the body. This ancillary study will collect additional blood samples at multiple times after injury and use advanced genomic, protein, and metabolite analyses to understand the systemic processes affecting bone health. By examining circulating immune cells and biomarkers, researchers hope to map how injury-related inflammation and other biological signals contribute to future fracture risk. The goal is to identify potential pathways that could be targeted to prevent additional bone loss after a fracture.

Why it matters

Potential benefit: If successful, the findings could lead to new ways to protect bone health after injury and reduce future fracture risk.

How similar studies have gone: Previous research suggests systemic bone loss after fracture is real, but this study uses a comprehensive multimodal blood analysis that is relatively novel in this context.
