The life expectancy of an elderly person after a fracture depends on many factors, first of all on the severity of the fracture site, whether it can affect his daily life and whether he needs strict bed rest. If the fracture is relatively minor and does not affect daily life and functional exercise on the ground, it will have relatively little impact on the life expectancy after the fracture. However, there are many elderly patients who have poor cardiopulmonary function after the fracture, which seriously affects the surgical treatment and the early activity on the ground, and may need bed rest, and at this time the impact on the life expectancy is very great. According to research, if the elderly cannot walk on the ground after fracture, they need to be bedridden for a long time, and the mortality rate will be very high if they are bedridden for more than six months. Therefore, early mobility can extend the life expectancy of the elderly, but prolonged bed rest can seriously shorten the life expectancy of the elderly.
