Not many feet have a generic shape, yet we seem to see people being fitted with a generic shaped shoe.
Normally that would pass, but when you have a complication like diabetes, the risk is far too and needs to be addressed by better fitting footwear and in the case of charcot, custom made footwear and orthosis is the only save way to go.
In the image of the pressure mapping, the feet are of the same size, but very little surface of the charcot foot is touching the pressure mat, increasing the pressure and the risks.
l often get asked why a charcot deformity requires custom footwear.
The answer is often found by measuring the plantar pressure, even in the static moment as we have done here.
To the left, plantar pressure in the static, a patient with charcot deformity, two amputations and two active ulcers and really struggling to just retain their balance. We chose not to take a dynamic due to the current active ulcers.
To the right, plantar pressure of myself, mainstream foot structure and function with no balance issues, just as an example.
This data capture forms three crucial rolls, because its objective and repeatable.
The first and most important part, that is patient education, this data allows us to talk to patient and their family about where the risks are and why. Explaining the target is 200kPa in the dynamic, they measured 432kPa under the right in the static, it will be higher in the dynamic.
Second part is reporting our finding to the referrer to ensure they too understand why we are taking the actions that we are.
Third part is to support our justifications for intervention and report our findings to the funding bodies.
So the question of what type of footwear is based on the foots ability to change to the form of the footwear, most footwear having 19mm of heel pitch and toe spring of 16mm.
The charcot, fused foot cannot change its form nor can it flex to match the shape of the mainstream footwear profile, so we need to make the footwear and orthosis to match the feet, we need to cradle and control and in this case no heel pitch or toe spring.
The data in the image is taken using a MobileMat, a pressure measuring device.
