Three-Dimensional Finite Element
Analysis of Human Femur:
A Comparative Study
Amrita Francis, Raji Nareliya and Veerendra Kumar
Abstract Three-dimensional finite element analysis (FEA) is widely used to
generate reliable subject-specific finite element (FE) model using computed
tomography (CT) data that accurately predicts information about bone morphology
and tissue density. FEA provides detailed information regarding displacement,
stress, and strain distributions along the entire bone. CT scan data is widely used to
make realistic investigations on the mechanical behavior of bone structures.
The purpose of this paper is to create anatomically accurate, three-dimensional
finite element models of the right human femur of three male patients of different
age groups of 17, 32, and 40 years, respectively, using CT scan data, loaded by
physiologic forces, i.e., half-body weight. An average body weight of 70 kg
(686.7 N) is assumed for this study, which is shared equally by the lower limbs
according to the hip mechanism; hence, a load of 343.35 N (half-body weight
analysis of this model will provide data unavailable at this time to orthopedic
surgeons, engineers, and researchers) is applied on each right human proximal
femur that affects femur during weight bearing action at different angles and to
determine the total deformation, equivalent Von-Mises Stress distribution, maxi-
mum principal stress distribution, and fatigue tool throughout the whole femur and
comparing the results of human orthopedics.
