Abstract
Micro-finite element (µFE) analysis is a numerical technique to calculate mechanical properties of trabecular bone as they relate to its micro-structure. It is based on two recent developments. The first is a method for the three-dimensional graphics computer reconstruction of trabecular structure. With this method, high-resolution images of sequential cross-sections of a trabecular bone region are created. These images are digitized and stored in a computer. By stacking the cross-sectional images the original structure can be rebuild in the computer as a three-dimensional voxel (i.e. 3-D pixel) grid. Methods to create the high-resolution images can be destructive (e.g. serial sectioning and serial milling techniques1,2) or non-destructive (e.g. µCT and µMR imaging3,4.5,6) In both cases a resolution of 50 microns or better can usually be achieved for trabecular bone regions of approximately 1 cm3in size.
