Femur fracture how long can get down to the ground depends on the situation: first, if the bone fracture is not serious, the fracture dislocation is not obvious, just a bone fracture, and did not do surgery but external fixation, this time generally need to be fixed for 6-8 weeks, 8-12 weeks when you can gradually get out of bed weight-bearing activities. Of course, it is not entirely based on time, we should take pictures to further understand whether there is a bone scab growth, (to) the growth of the bone scab depending on the situation. Secondly, if the femur fracture is more serious, the incision and reduction of internal fixation, this time generally need 6-8 weeks after the crutches weight-bearing activities out of bed. If it is an open femur fracture, or even a combination of soft tissue defects, the fracture is likely to have a delayed healing, non-healing, there is no way to fully determine the time to get out of bed, it may be half a year later, or even a year later may be possible.
