Synthes The Titanium Femoral Nail System, Technique Manual

Remove the wire sleeve, slide
the black measuring device
over the wire, and measure
for direct screw length. (This
device measures to the tip of
the guide wire.)
Remove the measuring device.
Insert the self-drilling/self-
tapping screw into the femoral
head through the protection
sleeve using the cannulated
screwdriver.
In very dense bone, the
surgeon may predrill and tap
the near cortex through the
protection sleeve with the
5.0 mm cannulated drill bit
and cannulated tap.
Note: If the surgeon prefers 6.5 mm Titanium Cancellous Bone
Screws, use the 3.2 mm wire sleeve(s) with 3.2 mm trocar through
the Miss-A-Nail jig. Insert the 3.2 mm calibrated guide wire through
the sleeve and into the femoral head until it is just short of
subchondral bone. Press the sleeve to the lateral cortex and read
screw length from the guide wire at the back of the sleeve. This
measurement will place the screw 5 mm from the guide wire tip.
Remove the wire and tap as needed with the tap for 6.5 mm screws.
Select a screw equal to or shorter than the reading and insert the
cancellous screw with the standard screwdriver.
