Hi,
I've been treating a young diabetic w a two year history of neuropathic ulcers. When no infection occurs his healing rates are very good however with offloading techinques in his orthotics I have found an increased risk of friction related problems in other areas of his feet.

Has anyone got any advice on the best way to reduce surface friction in orthoses for this patient?

Thank you,

Jaimee

 

I would consider using a material similar to memory foam that they use for mattresses. It compresses and absorbs shock while not developing as much friction as some other top coverings.

Hi Jaimee,

Carlson (2011) presented the following coefficient of friction (COF) values for the material he makes (Shearban) versus 4 other materials in dry and (moist) conditions:

- Shearban: 0.17 (0.17)

- Russett Leather: 0.18 (0.52)

- Poron: 0.31 (0.51)

- Spenco: 0.51 (0.61)

- Plastozote: 0.73 (0.68)

Thank you

Thats great

 

Jaimee have you see Dave Armstrongs work in this area? Might be worthwhile looking it up - good place to start may be his work with Vasyli Medical on his off the shelf sheer reducing innersole, I know there is references to his work there. I will try and dig some content up off PORTAL Education with you as well and post it here.
