Charcot Foot

Charcot foot is a condition in which the bones in the foot gradually weaken until they begin to fracture.  Joints can even dislocate in the foot or ankle.  Extended walking on the affected foot may cause the joints to collapse resulting in deformity, such as a “rocker-bottom” appearance.  Once the foot changes shape, it can cause pressure sores, ulcers, bone infection, and may even lead to amputation.  Charcot foot is more common for people who are diabetic, suffer from neuropathy, or any trauma that has been inflicted.  Symptoms of Charcot foot may include redness, pain, swelling, and warmth to the touch.

A common non-surgical treatment method for Charcot foot is known as “offloading”.  Offloading refers to taking the weight off the affected foot.  This helps prevent further progression within the early stages of the condition while also preventing inflammation and deformity.  Walking in a walking boot, also known as protected weight-bearing, helps in later stages because it can prevent complications and avoid new deformities. A cast, crutches, knee walker or wheelchair may also be involved as part of the “offloading” treatment.  Special footwear is a used to treat Charcot foot typically after “offloading”.  Prescription orthopedic footwear may prevent Charcot foot from recurring as well as ulcers. 

In severe cases, surgery may be recommended to treat Charcot foot.  If the casts, braces, or walking boots are difficult to use due to the foot’s deformity, surgery may be advised as well.
