Insert guide wire for screw
Instruments
357.383 3.2 mm Trocar
357.399 3.2 mm Guide Wire, 400 mm
Note:
For positioning the guide wire, refer to the optional
technique for using the guide wire aiming device (page 22).
Remove the 3.2 mm trocar and pass a new 3.2 mm guide
wire through the drill sleeve to the bone. Advance the guide
wire, under power, into the femoral head, stopping approx -
imately 5 mm from subchondral bone. The guide wire should
be centered in the femoral head and neck in both the AP
and lateral planes. The tip of the guide wire is positioned at
the intended screw tip position.
Confirm guide wire placement, in both planes, using the
image intensifier.
Note:
If the nail must be repositioned to improve guide
wire placement, turn the buttress/compression nut clockwise
to retract the blade guide sleeve and use the insertion handle
to make the adjustments. Do not pull on the blade guide
sleeve or the drill to make this adjustment as this could affect
the accuracy of the aiming assembly.
