FIGURE 5.

A 5-year-old girl sustained a short oblique fracture of the femur when injured in a pedestrian-motor vehicle collision. (A) The radiographs obtained 4 weeks after the injury showed moderate retrotorsion of the femoral neck. This external rotational malalignment should not have been accepted (B). Union of the fracture was confirmed by radiographs after 5 months, and there was minimal retrotorsion of the femoral neck (indicated by the angle) in the lateral view indicative of minimal external rotational malalignment (C).
