Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This study is testing whether a computer tool called MEKANOS can better predict the risk of hip fractures in people with Fibrous Dysplasia or McCune-Albright Syndrome. Researchers will take CT scans of the femur and use the tool to calculate bone strength. The goal is to improve fracture risk assessment, not to test a new treatment. About 20 adults with confirmed diagnoses will participate.

Inclusion Criteria: * Adults with Fibrous Dysplasia (FD) of the bone or McCune-Albright Syndrome (MAS); * who have received care at the center through outpatient consultation, multidisciplinary evaluation, or hospitalization; * whose diagnosis was confirmed by an expert physician from the reference center based on a combination of clinical, biochemical, and radiological criteria, in accordance with the recommendations of the international FD/MAS consortium (Javaid MK et al., Orphanet J Rare Dis. 2019); * for whom a histological confirmation was obtained in cases of diagnostic uncertainty; * no objection to data collection Exclusion Criteria: * \- CT scan with implanted material on the femur, * Individuals under legal protection measures
