DESCRIPTION

Charcot Foot is a pattern of bone and joint destruction that can lead to severe foot deformities. This disease usually begins with peripheral neuropathy (decreased feeling in the feet) and decreased blood circulation, most commonly seen in diabetics. People with decreased nerve sensation may injure their feet, producing small fractures in the bones; and because they have decreased feeling, they may have minimal or no pain, and they continue walking on the foot. This combined with the lack of ability to heel by having limited circulation weakens the supporting structures of the foot and eventually result in the deformity.

The acute, or early symptoms of Charcot Foot are: small fractures of the bones of the foot, swelling over these areas, and later the entire foot may become swollen and inflamed. There is little, if any pain during this stage. Treatment during this stage is imperative, and includes: complete rest of the foot by using a non-weightbearing cast, crutches, and bed rest. If treatment is not initiated, this disease progresses to its chronic stage. During this stage the following symptoms may be present: a foot which is deformed, and noticeably different then the other foot; a collapsed arch; bones which abnormally protrude against the skin, possibly causing the skin to breakdown and ulcerate; swelling and inflammation of the foot; and there may be no pain present, or in some patients the pain is intense, due to the amount of bone and joint destruction present. Treatment during this stage involves non-weightbearing casts until the swelling subsides, physical therapy, and custom-made shoes and orthotics.

TREATMENT AND PREVENTION

Anyone who has peripheral neuropathy, especially diabetics, should be treated with custom molded orthotics to help guard the feet against injuries; to support the bones and joints of the feet, thus preventing deformities from occurring; and to protect the bottom of the feet from friction, calluses, and ulcers of the skin.

Examine your feet daily including the tops, bottoms, and between your toes. Look for inflamed areas, cuts, peeling and breaks in the skin, rashes, and swelling. Press on your nail to see if they are painful or ingrown. Touch your feet and make sure the temperature is the same in both, and that they are not cooler then the rest of your body. Test to see that you have good feeling in the bottom of both feet, by gently moving your finger from heel to toes. If any of the above is abnormal, see a podiatrist immediately. Wear properly fitted supportive shoes with the toe box (the area where the toes lie in the shoe) being deep and wide to reduce pressure on the toes, the heels should be no higher than 3/4 inch. Rocker profile of the forefoot helps. Seamless socks and shoes cause less problems then those with seams. Always wear shoes and socks; they protect the feet from injury. Do not walk barefoot.
