Research project: Finite element analysis of a cementless proximal femoral stem in relation to early stem stability and interface bone strain

Currently Active: 

Modern cementless hip stems rely on achieving initial stability as measured by micromotion at the bone-implant interface to allow bone ingrowth in order to fix the stem to the supporting bone.

Many factors including stem geometry, size, surface texture, bone quality, the presence or absence of interference-fit and loading of stem influence the initial stem stability. This project examined several factors influencing the initial stability of the stem, including bone quality, degree of interference-fit and the effect of viscoelastic creep of bone on the degree of interference-fit, to improve the preclinical assessment of cementless hip stem.
