简介：
Overview
This protocol enables the observation of the microstructure of the whole human femur as it deforms under load and fracture. By imaging the whole femur with microstructural resolution, this protocol makes it possible to study how the different trabecular cortical compartments of the bone synergistically determine its capacity to withstand load.
