When treating diabetic foot ulcers, the first thing to do is to clarify the grading of the ulcers, and different treatment methods are used for different grades. If the wound is small, it can be treated by changing medicine; if the wound is large and deep, it needs to be thoroughly debrided; if it is combined with infection, it is necessary to take the secretion of the wound to do bacterial culture and drug sensitivity test, to choose the appropriate antibiotic to treat the infection, and at the same time, remove the necrotic tissues through surgical operation. In the past, the treatment of diabetic foot was amputation. At present, transverse bone handling technology is used to induce blood vessel regeneration by pulling and stimulating the bone block, and rebuild the patient’s blood circulation through blood vessel regeneration to realize the purpose of preserving the foot.
