Supine knee flexed 30°
This position is useful for antegrade nailing or retrograde nailing as the ability to obtain AP and lateral X-rays is exceptional.
Scissoring makes length, alignment and rotational confirmation easy. Raising the injured leg facilitates reduction of any flexed proximal fragment (iliopsoas muscle).
Lateral decubitus position
This position is recommended for very proximal fractures because finding the entry-point is easier. However, it is more time consuming and iatrogenic injuries to the pudendal nerve have been documented, due to prolonged or excessive traction. This position is also recommended for obese patients.
