Diabetic foot refers to lower limb infection, ulcer formation and/or deep tissue destruction in diabetic patients due to the combination of neuropathy and various degrees of peripheral vasculopathy. Clinically, diabetic patients are affected by long-term hyperglycemia, which leads to lower limb vascular sclerosis, vessel wall thickening, and decreased elasticity, resulting in the formation of blood clots and plaques, causing lower limb vascular occlusion and limb nerve damage, resulting in lower limb tissue lesions. The “foot” is the farthest from the heart, and the occlusion is the most serious, leading to edema, blackening, decay, necrosis, and gangrene. The etiology of diabetic foot is multifactorial, with diabetic neuropathy, peripheral vascular disease and microcirculatory disorders as its main causes. Diabetic feet are particularly susceptible to vascular and neurological lesions. Diabetic vascular and neurological lesions interact with each other to cause a range of clinical foot conditions, including toe disease, callus formation, skin damage and foot ulcers, and musculoskeletal lesions leading to foot deformities. Diabetics are often susceptible to trauma due to neuropathy, which can quickly lead to ulceration, infection and gangrene, and eventually to amputation if left untreated. The diabetic foot belongs to the category of “gangrene” and “tendon gangrene” in Chinese medicine. The specialty of surgical ulcers in our hospital, playing the specialty of Chinese medicine in the treatment of chronic ulcers, has been engaged in the treatment of diabetic foot for a long time, and summarized a set of treatment plan and clinical pathway for the treatment of diabetic foot mainly by Chinese medicine. We have developed a set of Chinese medicine based treatment plan and clinical pathway for diabetic foot. For example, in the internal treatment of diabetic foot, in the acute stage, the first step is to remove the evil, so as to clear the heat and dampness and detoxify; in the improvement and remission stage, to support the righteousness and strengthen the root, so as to benefit the qi and nourish the yin and tendons. Externally, the early stage of treatment is to remove the toxin and swelling; the middle stage is to clear the wound and remove the decay; and the late stage is to produce muscle and close the mouth. A variety of traditional Chinese surgical medicines and therapies, such as Chinese fumigation, hooping, plasters, ointments and adulteration, have been used to achieve good results. In recent years, with the in-depth research on diabetic foot at home and abroad, new series of dressings for diabetic foot and various therapies such as negative pressure therapy have been continuously developed, which have been introduced in our hospital in time and applied in clinical practice, complementing the traditional methods of TCM to obtain better curative effects. Over the years, the surgical sore specialist has saved many patients who were on the verge of amputation by using a combination of Chinese and Western medicine, and has won a good reputation. The treatment of diabetic foot is a complex project involving many disciplines. The foot lesions of diabetic foot must be professionally treated, and incomplete treatment of the trauma may lead to serious consequences such as amputation. Early detection, early treatment, collaboration of different disciplines and specialist management are the best way to reduce the amputation rate.
