Dislocated ribs are displaced rib fractures, and there are different treatment options depending on the number of rib fractures and the degree of displacement of the patient.1. As a general principle, analgesia, immobilization of the thorax and prevention of complications such as accumulation of respiratory secretions should be provided.2. Treatment of displaced rib fractures differs from patients with fractures of the extremities in that strict repositioning of the fractured ends is not required. If the fracture is a simple rib fracture without complications such as shackled chest and paradoxical breathing, local compression bandaging can be applied. 3.If multiple rib fractures combined with paradoxical breathing are large in magnitude and affect respiratory and circulatory functions, emergency surgery should be performed to fix the thorax and give anti-shock and anti-infection treatment at the same time. 4.Patients with open displaced rib fractures should be treated with early debridement, and those with combined open pneumothorax should have closed thoracic The patient with open displaced rib fracture should be treated as early as possible.
