for TFN
If the fracture line is perpendicular to the axis of the head el-
ement or if rotational control of the femoral head during
head element insertion is a concern, the following technique
may be utilized.
After the guide wire has been inserted, attach the
Miss-A-Nail jig to the aiming arm either anterior or posterior
to the nail. Set the thumbscrews to desired wire spread
position and tighten using the 11 mm ratchet wrench. Leave
the 11.0 / 3.2 drill sleeve assembled in the blade guide sleeve.
Pass the 5.6 / 3.2 drill sleeve through the Miss-A-Nail jig.
Make a stab incision and pass the sleeve to the bone. Ad-
vance 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 head
element, in the lateral view, but will not touch it. The guide
wires should be used for provisional fixation only and re-
moved once the head element has been inserted.
