Registry for Atypical Femur Fractures in Quebec

Quebec Registry for Atypical Femur Fractures

Observational McGill University · NCT02150850

This study looks at older adults in Quebec who have had unusual thigh bone fractures to see how certain medications and bone structure might affect their risk of these injuries.

What this trial studies

This project aims to characterize clinical, biomechanical, radiological, and genetic predictors of atypical femur fractures (AFF) in patients aged 45 and older from Quebec. It focuses on individuals who have sustained an AFF, particularly in relation to the use of bisphosphonates and denosumab therapy. The study will analyze the unique geometrical variations of the femur in these patients, hypothesizing that specific mechanical forces contribute to the occurrence of these fractures. By gathering comprehensive data, the study seeks to enhance understanding of AFF and its risk factors.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 45 and older from Quebec who have sustained an atypical femur fracture.

Not a fit: Patients with disorders of bone metabolism other than osteoporosis or those with active cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to improved identification and management of patients at risk for atypical femur fractures.

How similar studies have performed: While the study focuses on a specific subset of fractures, similar observational studies have provided valuable insights into fracture risks associated with osteoporosis treatments.
