A twisted rib cortex is also considered a fracture because the definition of a fracture is that the integrity and continuity of the bone is disrupted due to an external force, including some patients who have a bone that is not broken, but the integrity is disrupted, or the cortex, medulla, or trabeculae of the bone are discontinuous is also considered a fracture, so any interruption of the trabeculae is called a fracture when viewed under a microscope. This patient asked about the distortion of rib cortex, probably because he took X-ray, DR film or CT film in the hospital and saw some distortion of rib cortex, which means that the patient’s rib has been fractured, so the distortion of rib cortex is also considered as a fracture, and it should be treated according to the treatment of fracture with repositioning, immobilization, functional exercise and medication.
