The normal postoperative oozing after ankle plate is caused by trauma and surgery, and it may also be caused by incomplete hemostasis during the operation or abnormal coagulation function of the patient himself. 1. Normal postoperative oozing: after ankle fracture, capillary rupture will be caused, resulting in local bleeding. Surgery is only for fracture repositioning and fixation, and it takes time to repair the rupture of small blood vessels; at the same time, the surgery itself may also damage local blood vessels, resulting in postoperative oozing. 2. Special circumstances: a small number of patients with more postoperative oozing or longer time after ankle surgery, there may be postoperative oozing caused by incomplete hemostasis during the operation, and at the same time, postoperative edema of the affected limb will aggravate the oozing; in addition, if the patient himself has abnormal coagulation function before the operation, but does not meet the contraindication for surgery, there may also be a postoperative oozing of blood from the incision. There may be other reasons for the blood seepage after ankle plate, we suggest to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
