The amount of time that a fracture of the neck of the femur can be physically active after healing is related to physical health, treatment and the type of fracture. Generally it takes 3~6 months after healing for the elderly and 6~12 months for the young. 1. Elderly people: If elderly people suffer from femoral neck fracture, the surgical methods adopted are applying artificial femoral head replacement and artificial hip replacement, which can allow them to walk on the ground and have functional exercises at an early stage. If actively exercise for 3 months, the basic function has returned to normal, able to do some light work. Doing physical work is recommended after 6 months. 2. Young people: If you are a young person, it is not recommended to do hip replacement, usually applying screws for internal fixation, the fracture healing time must be 3 months to half a year, and some patients have to reach one year. After the fracture has healed, it is recommended to decide on physical activity after 6 to 12 months of patient recovery. It is necessary to review the photographs to see that the fracture is completely healed, the bone scab is growing relatively well, and even the bone marrow cavity is clear before you can work. A fracture of the neck of the femur requires active medical attention and rational treatment as prescribed by the doctor.
