High resolution voxel based finite element models of trabecular bone have recently become popular as a method to investigate the properties of trabecular tissue (van Riethergen et. al., 1995; Ladd et al., 1997; Huo and Fhyrie 1995) and the effects of microstructure on apparent properties (Hollister etal., 1994). In these model, high resolution (20-80 micron) images of the trabecular bone are converted to finite element models by assigning an 8-noded brick element to each image voxel (Fhyrie et al., 1992). As these models come into more widespread use, it is important to quantify their numerical convergence characteristics.
