NCT ID NCT01747291
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is building a registry of 300 people in Ontario who have had a rare type of thigh bone fracture called an atypical femur fracture. Researchers want to learn more about what causes these fractures, which have been linked to long-term use of osteoporosis drugs called bisphosphonates. By collecting detailed information from patients, they hope to identify risk factors and improve prevention.
