Dear All

Thanks a lot to those who replied to my query on the matter above. A
summary of the suggestions received is listed below :

I found an article, entitled 'A finger function simulator and the
laboratory testing of joint replacements' in Proc Instn Mech Engrs part H:
J Engineering in Medicine 1990;204:233-40.

- Bart Verkerke

The American Society for Testing and Materials (ASTM)
(I think it is has tried for a number of years to
develop a standard to test finger prostheses. At this point there
is only F1781-97 that covers elastomeric flexible hinge finger
total joint implants. It is quite sketchy in the area of testing.

One issue is whether to include any axial torsion into
the test. One implant design did fine without any torsion loading, but
failed miserably clinically due to in vivo torsional loading.
