Charcot Deformity

What is Charcot?

People who have severe nerve damage (neuropathy) are susceptible to developing a condition that causes weakening of the bones in the foot. This is known as “Charcot.” The bones of the foot can fracture, and with continued weight bearing, Charcot can lead to significant deformity. The small joints of the foot collapse as the disorder progresses, eventually causing a “rocker bottom” appearance. This can be a very dangerous situation as wounds can form on the bottom foot making the limb at risk of amputation. Therefore it is important to take preventative measures by seeking a foot and ankle specialist in a timely manner.

Causes

Charcot foot occurs because of neuropathy (nerve damage). In North America, neuropathy is most commonly caused by uncontrolled diabetes. With the reduced sensation of temperature, pain and trauma, diabetic patients continue to walk and destroy there foot without noticing it.

Symptoms (one foot)

• Swelling
• Warmth
• Redness

Diagnosis

After taking a thorough history to determine possible causes of neuropathy, your foot and ankle specialist examines your foot to rule out other possible causes of a red, hot, swollen foot (ex. Infection). Blood tests and x-rays are typically ordered and are often routinely followed.
