Utility and validation of bone mineral density measurements at forearm in predicting trabecular microarchitecture and central-site osteoporosis in aging Indian postmenopausal women-a promising surrogate?

Objective: The objective of this paper was to present the results of our study of the utility of bone mineral density (BMD) measurements at various segments of distal forearm in predicting central-site osteoporosis and deteriorated trabecular microarchitecture.

Methods: This was a cross-sectional study and BMD at the femoral neck, lumbar spine, and distal forearm were assessed using the dual-energy X-ray absorptiometry (DXA) scanner and bone microarchitecture at lumbar spine by trabecular bone score (TBS). The utility of forearm BMD in predicting osteoporosis as well as the deteriorated TBS was assessed by a receiver operating characteristic analysis.
