Generally speaking, hot compresses within 72 hours of femur fracture will aggravate the local swelling, and after 72 hours, appropriate hot compresses may have some effect on reducing swelling and pain.
1. Clinically, it is usually not recommended to apply hot compresses to the affected area within 72 hours of the fracture, because the injury time is too short at this time, and there is still intermittent bleeding at the fracture end, which will aggravate the bleeding and cause obvious swelling at the fracture area.
2. 72 hours after the fracture, because the bleeding of the fracture end is basically controlled, at this time, the affected area to do appropriate hot compresses can to a certain extent play a role in reducing swelling and pain, and will promote wound repair to play a certain effect.
It is recommended to consult a doctor as soon as possible after the femur fracture, and to carry out the resetting and fixation as soon as possible under the operation of a professional doctor, and then apply hot compresses appropriately in order to facilitate the repair.
