FRAX and FRAXplus Update
We have recently launched a parallel website to bring the FRAX web platform into the modern era, usable across a wide range of devices. (www.fraxplus.org)
FRAXplus® contains the most up-to-date FRAX calculators, freely available.
Additional features include access to an individualised FRAX account for storage of FRAX calculations and a beta-version, fee-based access to modifications of the FRAX probability (e.g. recency of fracture or falls in the previous year).
Once the FRAXplus® website is available in all the FRAX languages, the old FRAX website (https://frax.shef.ac.uk/FRAX) will be retired.
Welcome to FRAX®
The FRAX® tool has been developed to evaluate fracture risk of patients. It is based on individual patient models that integrate the risks associated with clinical risk factors as well as bone mineral density (BMD) at the femoral neck.
Dr. John A Kanis
Professor Emeritus, University of Sheffield
The FRAX® models have been developed from studying population-based cohorts from Europe, North America, Asia and Australia. In their most sophisticated form, the FRAX® tool is computer-driven and is available on this site. Several simplified paper versions, based on the number of risk factors are also available, and can be downloaded for office use.
The FRAX® algorithms give the 10-year probability of fracture. The output is a 10-year probability of hip fracture and the 10-year probability of a major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture).
Clarification
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 . Any references to the ‘WHO tool’
or to the WHO Collaborating Centre after it finished its work in 2010 are incorrect.
