When talking about this topic, one may wonder why fractures and high blood sugar are associated together. This is because the risk is higher in diabetic patients with fractures that tend to have wounds that do not heal. We all know that germs like to breed in places rich in sugar nutrients, and such a wound surface will inevitably have a high sugar content, which increases the risk of breeding germs. In addition to the fracture patients need to be bedridden experience, the lack of a certain activity exercise blood sugar or may rise greatly, the risk will be even greater. First, diabetic patients are inherently difficult to heal wounds, which mainly involves the blood sugar concentration affecting the activity of phagocytes, a particularly complex process, but the healing ability is reduced. Second, fracture wounds generally need to be bandaged and fixed, such as playing a cast. This will increase the risk of wound infection if the wound is sweaty, wet, etc. Third, there is also a risk of infection if the wound is stitched up. Like open wounds orthopedic or surgical are required to suture, diabetic suture mouth is difficult to achieve complete sterility, especially the anaerobic bacteria breeding in the wound, increasing the risk of infection. Fourth, the blood supply of the lower limbs. If the diabetic patient is old and has a long course of disease, the lower limbs may have peripheral vascular disease, which will also affect the healing of the wound. This situation does not have a wound will also appear infection, open wounds will appear more. Of course, these are only increased risks compared to patients without diabetes, and it is not certain that they will occur. As long as these problems are taken care of during the treatment and the characteristics of diabetic patients are taken into account, the chances of wound infections and ulcers will be reduced by taking precautions in advance.
