Abstract: Most of the studies available in the open literature make use of static analysis and discretisation of the load components for studying the mechanical behaviour of implants and prosthesis. The present study discusses the effect of time-varying loading on the prosthesis and femur bone assembly. The solid model of the femur bone was reconstructed using femur bone slices obtained from computed tomography (CT). The components of the hip joint forces and moments were applied at the femoral head of the prosthesis. The results from the present study were compared with the data from literature, and the present study shows that a time-varying loading analysis can provide much more realistic information about the prosthesis as compared to the prevailing use of static analyses.

Keywords: transient loading; CT; gait; finite element analysis; femoral prosthesis.
