There are 2 main types of rib fracture fixation: 1, external fixation of the chest strap, which is mainly suitable for single rib fractures or multiple sporadic rib fractures without the presence of a conjoined chest. By external fixation of the thorax, it can reduce the range of heaving of the chest due to respiratory movements, thus reducing the pain caused by rib fractures, and at the same time can effectively promote the healing of the fracture, moreover, it can stabilize the respiratory movements and avoid hypoxia. 2.Surgical internal fixation or external fixation, which is mainly used for multiple rib fractures, especially unilateral multiple rib fractures combined with the presence of a contiguous chest, due to the loss of rib support in the chest wall, during respiration Paradoxical activity occurs, which affects normal respiratory function, manifesting as chest tightness and breath-holding, and requires surgical internal fixation, or external fixation frame to fix several ribs to support the chest wall, so as to maintain normal breathing.
