To test the clinical utility of approaches for assessing forearm fracture risk. Among 100 postmenopausal women with a distal forearm fracture (cases) and 105 with no osteoporotic fracture (controls), we measured areal bone mineral density (aBMD) and assessed radius volumetric BMD, geometry and microstructure using high-resolution peripheral QCT; ultradistal radius failure load was evaluated in micro-finite element (μFE) models. Fracture cases had inferior bone density, geometry, microstructure and strength. The most significant determinant of fracture in five categories were: bone density (femoral neck aBMD: odds ratio [OR] per SD, 2.0; 95% CI, 1.4–2.8), geometry (cortical thickness: OR, 1.5; 95% CI, 1.1–2.1), microstructure (structure model index [SMI]: OR, 0.5; 95% CI, 0.4–0.7), and strength (μFE failure load: OR, 1.8; 95% CI, 1.3–2.5); the factor-of-risk (applied load in a forward fall ÷ μFE failure load) was 15% worse in cases (OR, 1.9; 95% CI, 1.4–2.6). Areas under ROC curves (AUC) ranged from 0.62 to 0.68. The predictors of forearm fracture risk that entered a multivariable model were femoral neck aBMD and SMI (combined AUC, 0.71). Detailed bone structure and strength measurements provide insight into forearm fracture pathogenesis, but femoral neck aBMD performs adequately for routine clinical risk assessment.
