Serial xrays of a two year old child with a badly displaced femur fracture,
showing gradual realignment of the bone over the course of 6 months.

The image on the left was taken at the time of injury, with the leg in a fiberglass cast.
The middle image was at 6 weeks and the right image at 6 months post injury.

Children rarely need surgery for these types of fractures because dramatic plastic remodeling
(straightening of the bone during the healing process) is possible in the very young.
