These are one of the most serious problems of the diabetic foot. Charcot joints usually occur in diabetics with relatively good circulation. The casts distribute the weight over the entire surface of the foot thereby decreasing the concentrated pressure that causes open sores. Total contact casts allow you to continue walking while you heal. The cast may seem inconvenient, but it can be very effective and much less expensive and risky than surgery.
Antibiotics are important.
But if you have poor circulation, antibiotics may not reach the infection. Most of the time foot ulcers and wounds are treated with dressing changes. A total contact cast may be used. Open sores are usually allowed to gradually close in on their own to prevent recurring infection. Surgery is sometimes required to clean out infected or poorly healing tissues.
