Most rib fractures occur in clinical practice when the patient is subjected to direct external forces. If a patient suffers a simple rib fracture with no major displacement of the fracture end, and the patient is seen in a timely manner, a clear diagnosis can be made by the physician, and the patient can be assessed as having a tenth degree of disability. If the patient has multiple rib fractures or a combined hemopneumothorax, the patient can be assessed as a Grade 9 disability. If the patient has a rib fracture and after proper treatment, the patient has a depressed thorax with a deformed appearance that affects the patient’s breathing, the patient can be assessed as a Grade 8 disability. The specific disability assessment criteria should be based on the national standards.
