A new method to determine trabecular bone elastic properties and loading using micromechanical finite-element models.

The apparent mechanical behavior of trabecular bone depends on properties at the tissue or trabecular level. Many investigators have attempted to determine trabecular tissue properties and loading. However, accuracy and applicability of all methods reported are limited. The small size of the trabeculae and a possible size effect are complicating factors when using traditional testing methods on...

Mechanical significance of femoral head trabecular bone structure in Loris and Galago evaluated using micromechanical finite element models.

Work on the interspecific and intraspecific variation of trabecular bone in the proximal femur of primates demonstrates important architectural variation between animals with different locomotor behaviors. This variation is thought to be related to the processes of bone adaptation whereby bone structure is optimized to the mechanical environment. Micromechanical finite element models were creat...

An imaged-based inverse finite element method to determine in-vivo mechanical properties of the human trabecular meshwork.

Aim Previous studies have shown that the trabecular meshwork (TM) is mechanically stiffer in glaucomatous eyes as compared to normal eyes. It is believed that elevated TM stiffness increases resistance to the aqueous humor outflow, producing increased intraocular pressure (IOP). It would be advantageous to measure TM mechanical properties in vivo, as these properties are believed to play an imp...

Assigning Material Properties to Finite Element Models of Bone: A New Approach Based on Dynamic Behavior

Finite element (FE) method is extensively employed to investigate the biomechanical behavior of bone structures. Material and morphological information of bone samples are typically provided by computed tomography (CT) scanning. Assuming that density and elasticity of bone are correlated, many studies have proposed different density-elasticity relationships to determine bone elastic constants. ...
