After the fracture of the foot, there are 3 main points to note: 1. After the fracture, cold compresses must be applied, because cold compresses can make the fracture caused by the small blood vessels to constrict, can reduce the fracture site blood seepage, reduce bruising and swelling to help the recovery of the fracture location, but also can significantly relieve pain and other symptoms. 2. After the plaster fixation or surgical incision and internal fixation, to The height of the foot should be higher than the level of the heart, which can effectively reduce the swelling and pain of the fractured foot through gravity. 3. After external plaster fixation and surgical fixation, the blood circulation and sensation of the distal end of the foot must be closely observed to avoid excessive pressure or local swelling due to plaster fixation. This may cause the ankle joint and the nerves and blood vessels in the foot to be compressed, affecting the blood circulation and nerves in the distal part of the foot and causing symptoms of ischemia and numbness.
