Pus in the fracture incision for six months is mainly considered to be caused by infection. Treatment mainly includes conservative treatment and surgical treatment. 1. Conservative treatment: If there is less exudation from the surgical incision, the skin temperature is not elevated, and the surrounding tissues do not have obvious edema, conservative treatment can be carried out. The main way of conservative treatment is anti-infection treatment, you can choose oral broad-spectrum antibiotics or intravenous antibiotics, such as cephalosporin, penicillin antibiotics, etc., and at the same time, give dressing change treatment. 2. Surgical treatment: If there is more oozing from the incision, obvious redness and swelling, and elevated skin temperature, surgical intervention is needed. Surgery is determined by the degree of infection. If it is only skin or subcutaneous infection, incision and drainage and debridement surgery can be chosen; if osteomyelitis is considered, it is necessary to open the window for drainage and decompression, clean up the dead bone, fill with artificial bone or bone cement, or even take out the internal fixation and so on. Postoperative anti-infection treatment is still needed. If there is pus in the fracture incision, it is recommended to go to the hospital in time and have standardized treatment under the guidance of the doctor.
