  • Stress shielding of bone.

    Dear All,

    I am cuurently working on a Finite Element Analysis of an
    endoprosthesis. The aim of this study is to evaluate the stresses
    generated within the implant and the bone. It is hoped that this
    information will provide a basis for optimising the implant design.

    Ther post-operative changes in the stress distribution in the bone
    can lead to stress shielding, and so cause bone resorption, and in
    some cases lead to the failure of the implant.

    I am interested to discover if a stress 'window' has been proposed
    for bone, where the stresses within this range would provide adequate
    mechanical stimulus to encourage 'normal' bone re-modelling.

    Any help would be greatly appreciated.

    Thanking you in advance.
