Subspecialty Section Rib fracture management in the older adult; an opportunity for multidisciplinary working Lauren Richardson and Shvaita Ralhan The elderly will soon make up the largest number of patients sustaining major trauma; a fall from standing height is their most common mechanism of injury1. Rib fractures are a common consequence of blunt chest trauma and are important to recognise and diagnose as complications can be fatal. They can be considered a surrogate for major trauma as up to 90% of patients will Lauren Richardson is an ST7 Registrar go on to have additional injuries identified2.
