  • Composite femur models

    Dear Biomch-ers,

    Some time ago I posted the following message:

    >I am working on the biomechanical validation of hip prostheses and am
    >looking for substitutes to cadaveric specimens. A synthetic femur model
    >for such purposes should:
    >- have similar geometry to the "average" femur;
    >- have spongy bone modeled a different way than cortical bone;
    >- have similar mechanical properties (including inhomogeneous and
    >anisotrpic elastic behaviour) to the "average" human femurs;
    >- be reproducible, for comparative testing.
    >The only commercially available models I am aware of are the Composite
    >femurs manufactured in the States by Pacific Research Labs, and imported
    >in Europe by Sawbones. Does anyone know of any other manufacturer of
    >synthetic models with similar properties?

    I received several mails of persons having the same question, but no
    response indicating other possible substitutes. As I feel this is still a
    useful piece of information, I am posting this message to remark that there
    seems to be only one (known) manufacturer in the world.
    Anyway, I will appreciate if anyone has any more info to share.

    Thanks to all who responded. Best regards.
