Abstract

Measurement of bone mineral density BMD by dualenergy Xray absorptiometry DXA is the recommended method for diagnosis of osteoporosis and assessment of future fracture risk However most patients who will suffer fractures do not have osteoporosis by DXA Tscore of −25 or less Bone strength which is most closely associated with resistance to fracture is a composite of both bone density and bone quality and the latter is not measured by DXA Thus other technology is needed for noninvasive and inexpensive assessment of bone strength and fracture risk Vertebral fractures the most common clinical fracture in the general population are of even greater importance in rheumatoid arthritis and other rheumatic disorders Vertebral fracture assessment VFA and trabecular bone scores TBS two techniques which can aid prediction of future fracture risk can be used with currently available DXA machines Description of these techniques and their potential application to clinical rheumatology practice will be the focus of this paper
