In the current work, the effect of difference in stiffness between implant and bone on the stress shielding effect was explored to assess the stress distribution when two different designs of fixing plates are selected (tubular and compression plates). The 3D finite element model of femur bone with plate and screw assembly was modeled by using CATIA V5 and the static analysis of the structure was carried out by using ANSYS Workbench. An axial compression load of 350 N was applied to resemble the human weight. Three cases were developed by using three kinds of bio-implant materials including 316L stainless steel, Ti6Al4V alloy and AZ31 Mg alloy. In each case, equivalent stress distribution has been observed in the implant and the fractured bone. It was observed that the stress shielding effect on bone by AZ31 Mg alloy plate was lower compared to SS 316L and Ti6Al4V alloy plates. Out of the two plate designs proposed, the range of stresses induced in compression plate is found to be higher and is suggested for long fractures. Where the tubular plate induced lower range of stresses and is suitable for smaller fractures. [ABSTRACT FROM AUTHOR] |
