Under normal circumstances, it is possible to walk normally on the ground after the nail is removed from the femur, and after the drainage strip or drainage tube is removed after the operation, it is possible to walk on the ground for about a week. However, at this time, the bone is partially nailed because the internal fixation has just been removed, and this part of the nail path is equivalent to the bone not completely healed, which may lead to re-fracture. After the nail is removed from the femur, it is necessary to avoid strenuous exercise at an early stage. If excessive strenuous exercise causes deformation of the bone, it is very easy to cause fracture in the original nail path, which requires surgery again. Therefore, it is recommended to move early after nailing the femur, but try not to exercise too vigorously to prevent the possibility of re-fracture of the bone.
