Trench foot
The mainstay of treatment, like the treatment of gangrene, is surgical debridement, and often includes amputation. Self-treatment consists of changing socks two or three times a day and usage of plenty of talcum powder. Wherever possible, shoes and socks should be taken off, feet bathed for five minutes, patted dry, talcum powder applied and feet elevated to let air get to them.
MDP syndrome
There may be different problems associated with MDP syndrome in the feet. The lack of subcutaneous fat means that there is direct pressure on the skin resulting in callus (hard skin) on the heels and also the weight-bearing parts of the forefoot. This is best managed by trying to find insoles to support the foot but it’s difficult to avoid completely. There is no approach that will increase the subcutaneous fat. The second feature is clawed toes as a result of contraction of the long extender tendons. The contractured constrictions can get worse over time. It is worth considering a physiotherapy referral with an aim to establish exercises to try to keep the tendons stretched if possible.
