Stanley,
If you wish I could forward you a copy of the paper. Feel free to contact my e-mail address to provide details as to where to send it. Unfortunately do not have paperless copy
regards
Tony

Subject: Re: Serial Casting for Internal Tibial Position
Tony and colleagues,
I just want to add a few things to what I wrote first of all I appreciate
the fine line of questioning. This really helps to refine our thoughts in
this area. Secondly, I am still bothered by the article you quoted. I would
like to see it in its entirety, as I feel there is something that is
important in it even though I cannot agree with its conclusions. I will go
to the library tomorrow and get a copy to read. Finally, I have used the DB
bar since I was a student at NYCPM in 1974. When I was a clinician at the
Podopediatrics clinic at OCPM in 1978-1981, there were approximately 40
patient visits daily, mostly for "slewfootedness" and "flatfeet" and
subsequently in practice. I haven't seen the joint laxity that you are
rightfully concerned about. On the other hand, in a few severe cases,
another podiatrist (who will remain nameless) used twister cables. I had
the opportunity to evaluate these children, and it was enough to disgust
me. The subtalar/ankle joint had horizontal movement that I still remember
to this day. There was also transverse plane movement in the knee. Enough
to concern me about a lifetime of arthritis. So I am painfully aware of
your concerns.
By the way, while we are on the topic of in toe, I think I found that the
reason for internal femoral position. During my fellowship, I read
Fitzhugh's article on sitting position (I think here first name was
Margaret) written in the early 1900's. the question was why do these kids
sit in the "W" position? I noticed that most of these kids were also
clumsy, and when they started to walk (prior to developing the in toe),
they would fall forwards and hit their knees and then their head, or they
would fall backwards and hit their heads. It seems that they did not spend
the normal 2 weeks in the sitting position at 6 months prior to crawling
(the majority of these kids), or they took an exceptionally long time to
walk, so they spent an exceptionally long time in the kneeling position. It
seemed that the kids that sat but took a long time to walk did not have the
clumsiness. My hypothesis is that the sitting position wires the balance
and reflexes around the hips, so the child when he starts to walk can stick
out his butt and land there. The child that misses sitting and therefore
ends up kneeling gets wired around the knee, so when he loses his balance,
he flexes his knee, which results in the falling. The rest of the
hypothesis agrees with Fitzhugh. The treatment to get rid of the
clumsiness, in addition to treating the internal femoral position, is to
develop balance around the hips. I have the mother sit with the child and
roll a ball back and forth to the child while the child is in the sitting
position.
Respectfully,
Stanley
