1
Position patient
Position the patient in the lateral decubitus or supine posi-
tion on a fracture or radiolucent table. Position the image
intensifier to enable visualization of the proximal femur
in both the AP and lateral planes.
For unimpeded access to the medullary canal, abduct the
upper part of the body approximately 10 –15° to the
contralateral side (or adduct the affected leg by 10 –15°).
Reduce the fracture. The universal large distractor may be
useful when not using a fracture table.

Instruments
357.391 Radiographic Ruler for TFN
357.399 Guide Wire
3.2 mm, length 400 mm
The three oblique slots at the proximal end of the radio -
graphic ruler can be used to determine the femoral neck an-
gle. Select a 3.2 mm guide wire and clamp the guide wire
into one of the grooves marked 125°, 130°, or 135°. Position
the ruler over the proximal femur and take an AP image.
Select the angle that most closely matches the angle of the
femoral neck.
