If the fracture line is perpendicular to
the axis of the screw or if rotational
control of the femoral head during
screw insertion is a concern, the follow-
ing technique may be used.
After the guide wire for the screw has
been inserted, attach the Miss-A-Nail
jig to the aiming arm either anterior or
posterior to the nail. Set the thumb-
screws to desired wire spread position
and tighten using the 11 mm ratchet
wrench. Leave the 11.0 mm/3.2 mm
wire guide assembled in the blade guide
sleeve. Pass the 5.6 mm/ 3.2 mm drill
guide through the Miss-A-Nail jig.
Make a stab incision and pass the
sleeve to the bone. Advance a 3.2 mm
guide wire into the femoral head.
Monitor passage with the image
intensifier.
Repeat to place a second guide wire.
The guide wires will converge toward
the tip of the screw, in the lateral view,
but will not touch the screw. The guide
wires should be used for provisional
fixation only and removed once the
screw has been inserted.
