Bone mineral density can be measured at various sites throughout the skeletal system and by various methods. The site of measurement can be either central (hip and/or spine) or peripheral (heel, forearm, or hand). Dual-energy x-ray absorptiometry (DXA) can be used to measure central and peripheral sites of bone mineral density. Quantitative ultrasound, peripheral quantitative computed tomography, radiographic absorptiometry, and single-energy x-ray absorptiometry are used to measure peripheral sites.

Noninvasive prediction of strength in vertebral bodies can provide valuable information for the assessment of the risk of fracture in human vertebrae [1-6], The aim of this study was to present an effective specimen-specific approach for predicting failure initiation locus in cadaveric vertebrae using a quantitative computed tomography (QCT) voxel-based finite element method (FEM).
