Diabetic Charcot foot is characterized by varying degrees of bone and joint disorganization secondary to underlying neuropathy, perturbations of bone metabolism and trauma. Offloading is the most important initial treatment recommendation. Surgery can be helpful in early stages involving acute fractures of the foot or ankle or in later stages when offloading is ineffective. Incorrect diagnosis and improper treatment often result in the extremity having to be amputated.
There are several surgical procedures accepted in Charcot foot surgery. Their goal is to obtain a plantigrade foot and prevent recurrent ulcerations. Arthrodesis is a well-known surgical procedure that addresses severe joint derangement through a surgically induced bony fusion. In Charcot foot, arthrodesis is usually indicated when there is significant skeletal instability. This procedure can be done by internal or external fixation.
