Instruments
357.383 Trocar 3.2 mm, length 232 mm,
for No. 357.381
357.399 Guide Wire 3.2 mm, length 400 mm
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 approxi-
mately 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
where the tip of the head element will be when it is properly
inserted.
Confirm guide wire placement, in both planes, using the
image intensifier.
Note: If the nail must be repositioned to improve guide wire
placement, use the insertion handle to make the adjustments.
Do not pull on the blade guide sleeve or the guide wire to
make this adjustment as this could affect the accuracy of the
aiming assembly.
