Osteoporosis is an important skeletal disease with serious consequences in the form of fractures. However, not every patient with osteoporosis suffers a fracture. It is crucial to select those patients who are endangered at a higher level. For that purpose the parameter of relative risk based on measurement of bone density has been used until now. It was shown that addition of clinical risk factors to the bone mineral density measurement markedly improves the risk assessment. FRAX is a computer model approved by WHO for fracture-risk assessment in primary health care. It enables assessment of fracture risk just from presence of clinical risk factors, even without bone density measurement. Through web application it provides for the physician (and even for the patient) a very easy and rapid fracture risk assessment.
