In patients with diabetes, the lifetime risk of diabetic foot ulcers (DFUs) is approximately 25%, and these wounds are frequently a source of pain and discomfort. Severe cases can even result in amputation of a portion of or the entire affected extremity. Proper classification of DFUs is essential for selecting the appropriate treatment course and coordinating care for the patient. Several systems are frequently used in classifying DFUs, although there is no universally agreed-on standard.
