Rib fracture usually requires 2-4 weeks of bed rest, the details are as follows: Firstly, if it is a simple single rib fracture, after external fixation with a chest belt, the patient can rest for two weeks, that is to say, the pain symptoms can be completely relieved and the respiratory function will not be affected, and the patient can move out of the bed and carry out functional exercises, so that the fracture will be recovered as soon as possible. Secondly, if there are multiple rib fractures, or even flail chest, surgery is needed in most cases. After the surgery, the patient needs to recover for 3-4 weeks before the pain gradually subsides. After the pain disappears, the patient needs to practice breathing activities, so after four weeks, the patient can leave the bed and start breathing exercises to restore the fracture and normal thoracic function.
