As the number of diabetic patients increases, the incidence of diabetic foot also rises. Currently, the prevalence of diabetic foot in China is 5.7%, which is below the global average. Diabetic foot primarily occurs in patients who have had diabetes for over ten years, often due to poor blood sugar control and inadequate care. Diabetic foot is also one of the three major non-traumatic causes of amputation. Therefore, the most severe consequence of diabetic foot is amputation.
