Generally, elderly people with femur fractures need at least 6 months to heal. The healing process is very slow in elderly people with femur fractures for the following reasons: 1. The gastrointestinal function of the elderly is much weaker than that of young people, so they are not able to absorb calcium, protein, vitamins and other nutrients in a timely manner, which is not good for the healing of the fracture. In addition, the metabolic rate of the elderly is much slower than that of young people, which is not conducive to fracture healing. 2. Many elderly people suffer from osteoporosis, and their own calcium deposits are not enough, so if a femur fracture occurs at this time, the fracture site needs even less calcium, which is not conducive to fracture healing. 3. 4. After a femur fracture occurs, it requires a lot of calcium to heal, and the femur needs to bear a lot of load, and it takes a relatively long time to heal completely. In summary, elderly people with femur fractures are very slow to heal, so it is recommended that such elderly people must listen to the doctor’s advice and undergo surgery for internal fixation as soon as possible, and in some cases, appropriate bone grafting is required. It is recommended that the elderly do not choose conservative treatment because once they are in bed, they may have a series of complications such as crushing pneumonia, urinary tract infection, pressure sores, and sometimes even direct elderly death.
