Dear All on mail base,
Please forgive me if I'm wrong but I
thought you were not supposed to send stuff as attatchments....greater risk
of viruses etc?.......I am keen to read what Howie has to say but it always
comes with / as attatchments.....and some computer geeks tell me not to
open them?....I've already had two embarrassing social conditions from the
group? Opinions please
Regards Phill Carter

Back to the issue of close packing. In my last post I noted three
statements
about the windlass and close packing of the calcaneo cupboid joint.
1. When acitvated the windlass causes a supination moment of the STJ.
When
the STJ supinates there will be adduction of the cuboid on the calcaneus
2. The close packed position of the CC joint is in its most abducted
position.
3. The windlass aids in close packing the CC joint.
Eric,
To continue......
I think that Bosjen-Moller described that the shift in body weight from
lateral to medial caused the CC joint to close-pack. Then, the windlass
supinated the foot. There are really two different mechanisms which
work in
rapid succession and succeed in creating a foot which is 1) stable to
the
forces which will develop later in the step and 2) timed with the
external
rotations which are being imparted from above (external leg rotation).
It is
the combined effect which is significant. When Fhl is present, it can
prevent either or both events as it can alter weight shift medially
(therefore preventing CC joint stabilization and secondly prevent timely
windlass effect when the 1st MTP joint fails to dorsiflex. I do not see
a
conflict in what I have previously described.

Howard Dananberg
