Design and non-linear finite element analysis of titanium-based femoral hip-stem for Indian population

In this research article, stress–strain and force–displacement analysis has been investigated at the bone-implant interface of implant models, utilizing a finite element analysis. On the basis of the standard geometry of solid femurs, structured long hip stems and applied the boundary conditions, including a stationary loading of 2300 N. This long hip stem implant shows the maximum mises stress at proximal end of femur stem 664.3 MPa with displacement of 1.263 mm having the elastic strain of 6.479*10^–3. When the hip stem implant is custom fitted in to the femur bone, the maximum stress is 13.01 MPa having the strain of 6.455*10^–03. Taking everything into account, the implant design with a ventured score in the proximal medial region demonstrated a general increment in von-mises stress circulation because of minimization of stress protecting managed by the diminished successful area in the bone implant interface. In this manner, this hip implant type could be a conceivable geometry to stay useful over the long haul in THR patients.
