Several weeks ago I had asked if anyone knows the modulus of
elasticity due to compression for the tibia. Finally, after I
looked the following answers (and Yamada's book) I came down to
this value:
9.3 GPa
I would like to thank everybody that helped me with my question
The answers that I received are:

Hi Nick,
A very good source of information on the mechanical properties of
bone, and the tibia in particular is:

@article{natali,
author = {Natali, A. N. and Meroi, E. A.},
title={A review of the biomechanical properties of bone as a
material},
journal={J. Biomed. Eng.},
volume = 11,
pages = {266-276},
year = 1989,
}

If the exact information you are after is not in the articel, which
I
doubt, there is certainly a reference where it can be found.

Best,
Pierre

Check Reilly & Burstein (1975, J Biomechanics). They tested human
femoral bone, but as long as the bone you're interested in is
adult, fully
dense, Haversian cortical bone, it's modulus shouldn't be site
dependent.
I believe their avg. modulus was 17 GPa, for tension and
compression.

We have recently completed a review of studies which have examined
the
biomechanical aspects of the tibia. Am not sure if the modulus of
elasticity
is included, as we were interested in the pressures, but the
studies which may
be helpful are:
Ackland, et al. (1988) Int J Biomechanics, 4, 146-155
Chu, M.L., (1986) J Biomechanics, 19, 979-987
Mungiole, et al. (1990), J. Biomechanics, 23, 1039-1046.

Hi Nick,
The elastic modulus of tibia in compression changes from 0.05 to
1.0 GPa dependson where you are taking your measurements, i.e.
cancellous bone vs. trabeculae.
K. Takahashi's article of "A stress analysis of the proximal tibia
after insertion of the endoprosthesis" is a good article to begin
a literature review.
