The World health Organisation designed an algorithm to evaluate fracture risk based on individualised patient models that interpret the risks associated with clinical risk factors as well as the bone mineral density of the femoral neck. The algorithm gives a 10 year probability of fracture risk, either of the hip, or of any major osteoporotic fracture including the hip. The algorithm can be applied with or without knowing the individuals bone density.

The information required is the patient?s age, height and weight, fracture history, family history of hip fracture, steroid use, alcohol and smoking habits and whether they suffer from other conditions such as Rheumatoid arthritis.

The algorithm can be found on the website of the World Health Organisation Collaborating Centre for Metabolic Bone Disease at the University of Sheffield, UK

The National Osteoporosis Guidelines Group (NOGG) was established to provide treatment guidelines for the management of men and women at high risk of fracture. They used the FRAX calculated risks to define thresholds for BMD measurements and treatments.

It is possible to view both sets of guidance (FRAX and NOGG) together by using the FRAX website and then once FRAX calculations are known, ask for the NOGG result which will suggest whether intervention should be considered.
