Osteoporosis and fracture risk calculator

The National Osteoporosis Society supports apps which make it easier for the general public to find out if they are at risk of breaking a bone. If the app helps them to find that they are at risk, we welcome functions which could help patients communicate this information to their GP.


A number of factors can put people at risk of osteoporosis and broken bones: these include their genetic profile, age, gender, ethnic background, body weight and history of previous fractures. Some medical conditions also increase risk.


The FRAX® tool is an example of such a fracture risk assessment app.


FRAX® enables users to input data about their own or their patients’ risk factors and generate a 10-year probability score of a suffering a broken bone. Developed at the World Health Organization Collaborating Centre for Metabolic Bone Diseases, University of Sheffield, the tool assists professionals to better target people in need of assessment or treatment. The tool can be accessed at or via iPhone Application.


The FRAX® tool generates the following results:


• the 10 year probability of a major fracture


• the 10 year probability of a hip fracture


• Body Mass Index


FRAX® is developed in partnership with the International Osteoporosis Foundation (IOF).
