A rotten diabetic foot definitely needs to be removed before further treatment. That is to say, there is no establishment without breaking, how to break it? First of all, the removal of necrotic tissue, after the removal, I hope that the blood flow of the foot can be further improved, this improvement through medication, and then do surgery in the second stage. The second stage of surgery has a direct coverage of the wound, removed from a blood-rich area, such as the abdomen, and then covered to the foot skin defects in the wound. There are larger surgeries that may require some other tissue, such as muscle tissue to cover the wound. So it depends on the patient, the cause of the patient’s condition. Whether the patient has an ulcer because of an irritation from the outside or an ulcer because of a vascular problem, the repair options are a little bit different. It can be treated simply by covering the wound with important blood-rich muscle and fascial tissue.
