The FRAX tool is designed to assist clinicians in predicting the ten-year probability of fracture with or without the addition of femoral neck bone mineral density (BMD).
It is freely available and is used for around 2.8 million fracture calculations per year.
The tool has been independently evaluated to be effective and robust, and has been approved by the National Institute for Health and Care Excellence in the UK and the Food and Drug Administration in the USA.
The University of Sheffield launched the FRAX tool in 2008. At that time the University hosted the The World Health Organisation (WHO) Collaborating Centre for Metabolic Bone Diseases (1991-2010), and the FRAX tool is based on data generated from that centre. However, FRAX was neither developed or endorsed by WHO . The University accepts that any references to the ‘WHO tool’ or to the WHO Collaborating Centre after it finished its work in 2010 are incorrect. We regret these mistakes and we are working to correct them wherever they appear.
