Answer

The most common mechanism of injury for rib fractures in elderly persons is a fall from height or from standing. In adults, motor vehicle accident (MVA) is the most common mechanism. Youths sustain rib fractures most often secondary to recreational and athletic activities, as well as by nonaccidental trauma. Rib fractures may also be pathologic. Cancers that metastasize to bone (eg, prostate, breast, renal) frequently become apparent in a rib. Ribs are relatively thin compared with major long bones and are more likely to fracture when invaded by a metastatic lesion. In a study of Japanese patients with rheumatoid arthritis who were followed over a mean duration of 5.2 years, 13.5% reported incident fractures, with rib fractures being the most common fractures in men and vertebral fractures being the most common fractures in women, followed by rib fractures.
