Treatment must be conducted after proper assessment of diabetic foot wounds. This implies appropriate foot care and the use of proper footwear from the perspectives of prophylaxis and walking. Diabetic foot wounds have some wound impairment factors, including peripheral neuropathy (PN), peripheral arterial disease (PAD), and infection; such wounds comprise combinations of these lesions. An additional goal besides wound healing is gait salvage. Here, we propose a simple new four-level classification of diabetic foot ulcerations, which we have termed the Kobe classification, in order to assess the wounds more easily and treat them systematically; the classification is as follows: Type I, mainly PN; Type II, mainly PAD; Type III, mainly infection; Type IV, PN+PAD+infection.
