Comput Methods Biomech Biomed Engin. 2024 May;27(7):825-835. doi: 10.1080/10255842.2023.2205978. Epub 2023 May 5.

Abstract

The increase of revision surgeries in hip replacement procedure in Colombian young adult population can be addressed by a new design of femoral stem that reduces stress shielding. A new femoral stem was designed using topology optimization as a design aid to reduce the mass in the femoral stem and its overall stiffness, combined with the theoretical, computational, and experimental assessment of the new design that complies with a static and fatigue safety factor greater than one. The new femoral stem design can be used as a design tool to reduce the number of revision surgeries caused by stress shielding.

Keywords: Femoral stem; axial fatigue; stress shielding; total hip arthroplasty.
