When a calf dehiscence injury occurs, a skin graft may be an option if there is no leakage of skin. Dehiscence injury refers to the tearing and separation of subcutaneous tissue and muscle fascia under the action of external force. The treatment of dehiscence injury should firstly stabilize the vital signs, and then carry out surgical treatment to repair the wound according to the situation. 1. First, the patient should receive active anti-shock treatment, such as fluid and blood transfusion, to stabilize the patient’s vital signs. 2. The surgeon should first clean the wound, stop bleeding and remove inactive tissues. Secondly, repair the wound and decide which surgical method to choose according to whether there is leakage from deep tissues such as tendons. In the absence of leakage, free skin grafting can be chosen; in case of leakage, skin flap transplantation should be chosen. In addition, if the situation is too serious, amputation can be chosen. After the surgery for calf dehiscence injury, you should pay attention to preventing wound infection, take proper nutrition, follow the doctor’s advice, and go to the hospital for regular checkups.
