REFERRING WOMEN AGED >70 YEARS FOR BMD ASSESSMENT INCREASES THE SUCCESS RATE OF IDENTIFYING OSTEOPOROSIS1
BMD is used for the diagnosis and monitoring of osteoporosis. BMD is most often described as a T- or Z-score, both of which are units of standard deviation. The T-score describes the number of standard deviations by which the BMD in an individual differs from the mean value expected in young healthy individuals.2
WHO operational definitions of osteoporosis and osteopenia based on BMD T-score.3
A wide variety of techniques is available to assess BMD. The most commonly used are based on X-ray absorptiometry of bone. DXA is the most widely used bone densitometric technique. It is versatile in the sense that it can be used to assess BMD of the whole skeleton as well as specific sites, including those most vulnerable to fracture.2
A recent update of the ESCEO guidelines states that women aged >65 years with a prior fragility fracture can be considered for osteoporosis treatment without the need for BMD assessment.4
