OANDP-L] Responses to petrochemical allergy

OANDP-L] Responses to petrochemical allergy

Thanks to all who responded to my inquiry. Here are the replies:
Original post: We have a client with an unusual history who requiresFOs.
According to the client, he sustained a head injury many years ago that
compromised or altered
his immune system response. He is allergic to any materials that are
petrochemically based in addition to or including all glues. We plan to
fabricate leather FOs but need a material to fill in / support arches, post,
balance, etc. Any recommendations?

I assume he is also allergic to the PE, EVA and rubber materials we all like
touse, so it won't be very soft, but:
Mold a leather shell, and add your fill material by creating layers of
leatherglued with white (Elmer's) glue. Sand off any glazed finish so that
thebuild up layers will stick. Sand and shape these leather layers as ever.

Best of luck!

Hi Jeff:
   How about carbon fiber with intrinsic forefoot posting? If youcould get
a lab to make them up for you, you get extra material laminated into the
heel for posting. You wouldn't need any arch filler.
   Can you please post your responses?

Natural Cork.

  
Jeff,
Consider some of the elastomere putty. OT's use it for scar management.
Good luck!

Contact the foot Guru...Barry Olman at UCO International...he has many
userfriendly materials...make sure you tell him about the allergies...he'll
also be in Phoenix. From: <Email Address Redacted> (Kaisha Gurry)

If you entirely cover the foot orthosis in leather i.e. top & bottom, then
the material to fill in would be encased and perhaps shouldn't cause any
problems.

How about that ancientadhesive called celastic which was used for creating
body jackets, TLSOs, inthe 50s and 60s. I believe it was made from celluose
acetate flakesliquified by acetone. It certainly securely bonded layers of
cottonstockinette together.

Is your patient allergic to pelite? It is a form of petro, polypro, butis for
all intents inert. I use 3/4-1&quot; pelite, molded over model, thenground
down to
fit. No glue, no cover, just pelite. Very durable, forgiving on thefeet, and
extremely light. Most leathers are tanned with chemicals so I wouldquestion
if
someone so allergic can tolerate.

why don't you use cork or even leather?

What about cork Jeff? RichardFrom: <Email Address Redacted> (Harry
Phillips)
You can obtain liquid natural latex and mix it with ground cork. In my
misspent youth as a sculpture founder this was used as an undercut filler
when making flexible reusable latex molds and predated (and was
substantially less expensive than) silicon molding compounds (which might be
an alternative). Art supply stores would be where I would look for it. It
is an air-dry material and build-ups of an appreciable thickness will take
some time to dry (it's been 25 years or so since I last did it--so I can't
recall exactly who long the drying time is). You might consider tryingthe
same stunt with medical grade silicon resin--if your patient can tolerate
that material--powdered cork would still be my filler of choice. Try molding
leather as the initial layer which you can mold and dry under vacuum. Hope
this helps.

Dear Jeff Gerl:

Have you considered the stainless steel Whitman Plate or standard FOs
availablefrom Apex? You can hammer on them to adjust the shape. Attaching
leatherwithout glue could be interesting, but you could sew a leather cover.
