Open the canal
With a power drill or hand
chuck, insert the 3.2 mm guide
wire into the entry point.
Pass the guide wire into the
medullary canal to a depth of
100 mm, confirming direction
and depth with the image
intensifier.
Using the tissue protector, drill
over the guide wire with the
13 mm cannulated drill bit to
a minimum depth of 100 mm,
approximately the level of
the lesser trochanter. This
opening will accommodate the
9 mm –12 mm nails, which are
12 mm in diameter for a length
of 90 mm from the proximal
end. Remove the drill bit.

Note: The surgeon may also use
the awl to identify the nail entry
point and open the canal.
For specialty locking and for 13 mm –15 mm
diameter nails, use the broach (from the Specialty
Locking Set) to enlarge the femoral opening to
accommodate a 15 mm sleeve. Fully insert the
broach into the femoral opening using a twisting
hand motion. Remove the 3.2 mm guide wire.
