Diabetic foot is a common complication of diabetes, and early treatment such as open therapy with Chinese and Western medicine can mostly avoid the mental and physical pain caused by amputation. Moreover, amputation itself is a risky operation, and a variety of postoperative complications can occur. Specifically, the postoperative complications of diabetic foot are as follows: 1. Bone and soft tissue are not yet in physiological condition, and dead bone will continue to be produced on this basis. 2, the presence of bone defects, due to the surgical removal of dead bone, or the formation of inflammatory cavities from the larger dead bones that fall out on their own, this cavity may cause the role of renewed pus, and continue to involve the bone and soft tissues. 3, soft tissue due to the stimulation of inflammation and the impact of surgery, the formation of too much scar tissue, blood flow worse, the ability to resist infection is reduced. 4, in the surgery has not taken into account the infection of the bone small cavity, and no repair of the internal environment and bone tissue destruction will continue to develop and expand. 5, due to the presence of inflammation, will continue to stimulate bone tissue to appear osteogenic effect, so that the bone trabeculae intensive proliferation again to form sclerotic bone tissue. 6.Some areas often lack skin and muscle coverage due to surgery and changes in the disease. Open infected wounds can create opportunities and conditions for continued bacterial infection. In order to prevent complications of diabetic foot surgery, patients must go to a regular medical institution when choosing a hospital and pay attention to postoperative care and prevention of infection.
