A fractured rib may be re-fractured when the patient rolls over, because the patient needs to exert force during the rolling process, when the chest muscles will exert force and then drive the rib. During the process of turning over, the internal displacement of the fracture site occurs again, resulting in a secondary fracture. The patient can turn over after the rib fracture, because lying down for a long time is easy to make part of the bone squeezed, and it is also easy to cause pneumonia and urinary tract infection. But in the process of turning over, patients must pay attention to wear a good rib external fixation belt, can be fixed at the rib. When turning over, it can reduce a certain external force, and then maintain the stability of the rib cage, which can reduce the chance of re-fracture. In the process of turning over, must let the side of the caregiver to give some help, in the turning over the caregiver can not touch the patient’s fracture, give some external force, remember not too hard to help the fracture patient to turn over. Fracture patients should not turn over too often, otherwise it is also easy to cause the second fracture.
