Lateral view of proximal femur.
(A) The shadows of femoral head, nail and targeting guide overlap.

Adjustment of the anteversion of lag screw
(A) Simulation with saw bones shows that the rotation of targeting guide determines position of lag screw in the femoral head.
(B) Corresponding C-arm views show shadows of 3-components, in which contours of targeting guides are outlined with solid line.
