Comparison of Bone Density of Distal Radius With Hip and Spine Using DXA

Osteoporosis diagnosis is usually based on examination of the hip bone and vertebrae density; however, the radius bone has gained attention recently in terms of feasibility and accessibility as it is done by portable devices with proper precision. This study aims to compare hip and spine density with radius, knowing whether radius may be an appropriate alternative for osteoporosis diagnosis. 120 females who were referred to one Densitometry Center checked their skeletal status using a hologic unit for densitometry of spine, femoral neck, and one-third radius. The patients were divided into three groups of healthy, osteopenic and osteoporotic based on WHO's protocol. Concordance analysis was done to investigate the degree of similarity of diagnosis. In the study, there were 40, 41, and 39 individuals with normal, osteopenic, and osteoporotic bone densities, respectively which obtained from hip bone or vertebrae using the T-score criterion T-score of radius bone density has a direct linear relationship with these result. Osteoporosis diagnosis can be made based on radius densitometry.
