People with diabetes are at a high risk for developing problems with their feet. More than half of diabetics lose sensation in their feet due to nerve or blood vessel damage, and can hurt themselves without knowing it. Diabetic patients can develop what we call neuropathy, which is a damaging effect to the nerves that makes it difficult to feel pain, pressure, heat and cold. To make things worse, diabetes slows healing and weakens the immune system, so what may seem like only a minor injury can quickly become a major problem for diabetics.
Surgical treatment procedure helps to achieve aims. The main goal is to control the deep infection, with the hope of salvaging the limb. This is accomplished by drainage of any pus, removal of all necrotic or infected tissues, and creating a healthy wound bed. It is also important to keep in mind the functional results after surgery. Residual foot deformities may lead to abnormal pressure points and, thus, reulceration. The surgeon must also consider the vascular status of the limb and the anatomic level at which a wound would be likely to heal. Furthermore, the surgeon must ensure that there is sufficient viable soft tissue to cover any deficits left by resections or amputations.
If you have diabetes, you should inspect your feet every day. Look for puncture wounds, bruises, pressure areas, redness, warmth, blisters, ulcers, scratches, cuts and nail problems. Get someone to help you, or use a mirror. Feel each foot for swelling. Examine between your toes. Check six major locations on the bottom of each foot: The tip of the big toe, base of the little toes, base of the middle toes, heel, outside edge of the foot and across the ball of the foot. Check for sensation in each foot.
