Conservative treatment of femur fracture requires continuous traction, due to the fact that the hip joint is more active when the knee joint is active, so the knee can not be flexed until the fracture of the neck of the femur is basically healed, which usually takes 8 weeks to 10 weeks. Femoral neck fracture is mostly caused by strong external force such as fall from height, car accident, etc. Its conservative treatment usually involves continuous traction on the treatment bed, avoiding hip activities and waiting for the fracture to heal, during which the X-ray needs to be reviewed regularly to observe the fracture healing. Because the knee flexion drives the hip joint to move together, and the lower limb needs to be continuously traction, so it usually needs the femoral neck fracture to be healed before the activity, usually takes 8 weeks to 10 weeks. Details related to the conservative treatment of femoral neck fracture, it is recommended to consult the doctor in time, under the guidance of the doctor.
