Dear Biomch-ers,

Some time ago I posted the following message:

>I am working on the biomechanical validation of hip prostheses and am

>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

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.
