Synthes The Titanium Femoral Nail System, Technique Manual

Under image intensification,
ensure that the bit has fully
penetrated the lateral cortex.
If a complete circle of cortex
is not removed, remove the
protection sleeve and
continue drilling. Closely
monitor drilling depth under
image intensification until the
cortical circle is removed.
Align the T-handle with the
femoral axis. Push the Spiral
Blade over the guide wire,
through the cortical opening
and into the nail slot. The
surgeon will feel the blade
engage the nail slot.
Note: If the Spiral Blade
doesn’t enter the nail slot,
ensure that:
•
The Spiral Blade entry hole
is deep enough (complete
cortical circle removed);
•
Guide wire angle = Spiral
Blade locking sleeve angle
(i.e., the 3.2 mm guide wire
has been placed through
the correct-angle bushing
in the aiming arm);
•
Spiral Blade locking sleeve
is correctly oriented on
the nail (check locking
sleeve under AP image
intensification to ensure
inferior side of slot is
positioned laterally);
•
T-handle of Spiral Blade
inserter is in line with
femoral axis (Spiral Blade
is aligned with nail slot).
