Greetings to all,

The following is a summary of responses that I received for my request
on help with femoral nailing. I would sincerely like to thank all those
people for their assistance and time to reply.

=================================
Here is my original message

Dear List Members

I am Mechanical Engineering student at the University of Natal,
Durban, South Africa. I am currently working on a project to
determine fatigue properites on an intra-medullary nail for the
femur. Before the fatigue test can be performed, I need to know what
type of loading conditions occur at the knee. In particular, I'm
interested in the resultant forces due to muscles, body weight and
ground reaction forces. If anyone has come across any such analysis
or information, I would greatly appreciate it you could share it
with me.

Thanking you in advance

Chetan Hira.

Dear Chetan,

There is an excellent book called "Advances in Artificial Hip and Knee
Joint Technology", ed. M. Schaldach and D. Hohmann, Springer-Verlag,
Berlin 1976. (ISBN 3-540-07728-6). It contains information on
physiological joint loading, among other things.

Try papers in Journal of Biomechanical Engineering, Journal of Bone
and Joint Surgery, and Journal of Biomechanics authored by John P.
Paul, G. Bergmann, A. Rohlmann, G. M. Kotzar, D. T. Davy, H. Kellner,
H. Rohrle, or R. D. Crowninshield.

Good Luck!

Dean Inglis

Hi Chetan,

I just found your email. You can check my home page for an abstract of
my thesis on the internal loads in the femur due to muscle activity.
It is on the publications page. If you have problems reading the html
or accessing a web server, let me know.

Greetings,

Georg

Chetan,
The literature is rich with data on knee joint forces -- unfortunately
not all of it agrees, which is mainly due to small errors which occur
in the measurement of motion and in locating orientations of soft
tissue and contacting surfaces. Nevertheless, there are a few papers
which stand out. I am assuming you are interested in knee forces
during gait. The majority of data available in the literature centres
around the patello-femoral joint, but I take it you are mainly
interested in femoro-tibial contact force? Some good papers to start
with are:

Morrison, JB "Mechanics of the Knee in Relation to Normal Walking."
ASME Biomedical Engineering, Vol 3., 1970, pp. 51-61 Nisell et al.,
"Joint Forces in Extension of the Knee" Acta Orthpaedica
Scandinavica, Vol. 57, 1986, pp41-46

but an excellent treatment of knee forces during gait can be found in:

Biden et al., "Gait Analysis" In: Knee Ligaments; Structure,
Function, Injury and Repair. Dale Daniel et al. (Eds), Raven Press
Ltd., pp. 291-310, 1990

This paper covers joint contact forces as well as ligament and muscle
forces during single limb stance of gait. If your library does not
have access to this book, let me know and I'll mail you a copy of the
paper -- the author was my PhD supervisor and I still have a few
copies of the paper floating around.

Yours,
Ronny

Did you consider just doing one of the (rapidly becoming) standard tests
for IM nail fatigue. ISO has one under development as does ASTM. You
should be able to get copies of both methods from the respective
organizations. I think I could come up with a copy of the ASTM
methods and may have a copy of the ISO draft. Loren Latta from Miami,
FL, USA should have them available.

Dear Chetan,

I was very interested to read your message on the Biomch Listserver. I
am trying to assess the forces generated in the joints of the lower
body with the objective of using this information to assess the
functioning and health of joints. The method I am using is to produce
a controlled impact of the standing body on to a load cell, and to
analyse the pattern of forces obtained.

I was particularly interested to read your message because I have also
been searching for information on joint forces. With the exception of
work done by Bergmann,G (1995. Influence of shoes and heel strike on
the loading of the hip joint. J Biomechanics 28: 817-827) on the hip,
I have found no direct measurements of joint forces. I am concerned
about the poor reliability of force estimations using inverse
dynamics analysis. This is particularly important because my work so
far has shown that posture, ie, the exact angles of bones, and muscle
tension have a very significant effect on the forces generated at
impact.

I would very much appreciate hearing more about your work, and any
direct measurement of forces in the legs you may have made or come
across.


With thanks

Jenny Fonseca
