(a) Anteroposterior radiograph demonstrating complete medially displaced left femoral neck fracture. (b, c) Computed tomography (CT) demonstrating the displacement of femoral head in the intrapelvic location, which had extruded through the obturator foramen.

Radiographs demonstrated an open comminuted fracture involving the distal right humerus, a short oblique fracture of the distal right femoral diaphysis, and a complete medially displaced left femoral neck fracture (Figure 1(a)). Computed tomography demonstrated the intrapelvic location of the femoral head, which had extruded through the obturator foramen (Figures 1(b) and 1(c)).
Anteroposterior (a) and lateral (b) radiographs taken immediately postoperatively.

The neck was then definitively fixed with four 6.0 mm partially threaded cannulated headless compression screws (Figures 2(a) and 2(b)).

The patient continued to experience pain with increasing ambulation, and serial radiographs obtained at three and four months demonstrated gradual hardware failure and displacement of the fracture despite appearance of callus and no evidence of AVN (Figure 3).
