Bone mineral density of the ultra-distal radius: are we ignoring valuable information?

Unlabelled: The current study explored the possible utilization in dual-X-ray-absorptiometry scanning (DXA) of the ultra-distal radius (UDR). This region of interest is currently unused and mostly unstudied in this context. The study findings suggest UDR as potential useful region of interest in DXA scanning and warrant further study of the site.

Bone Mineral Density of the 1/3 Radius Refines Osteoporosis Diagnosis, Correlates With Prevalent Fractures, and Enhances Fracture Risk Estimates.

Objective: To investigate the added value of 1/3 radius (1/3R) for the diagnosis of osteoporosis by spine and hip sites and its correlation with prevalent fractures and predicted fracture risk.

Methods: Fracture Risk Assessment Tool (FRAX) scores for hip and major osteoporotic fractures (MOF) with/without trabecular bone score were considered proxy for fracture risk. The contribution of 1/3R to risk prediction was depicted via linear regression models with FRAX score as the dependent variable-first only with central and then with radius T-score as an additional covariate.
