Drill for 11.0 mm screw
Instruments
357.369 Blade Guide Sleeve
357.403 6.0 mm/10.0 mm Stepped Cannulated
Drill Bit
357.404 11.0 mm Tapered Cannulated Drill Bit
357.405 Drill Stop
Remove the wire guide from the blade guide sleeve. Place
the 11.0 mm tapered cannulated drill bit in a power drill.
Pass the drill bit over the guide wire, through the blade guide
sleeve, and advance under power. Drill to the stop. This will
open the lateral cortex.
Note:
If the guide wire has deflected severely as it passed
into the femoral head/neck, it may be removed before
drilling and screw insertion. If the guide wire falls out or
comes out when the drill bit is removed, it may be left out
for screw insertion. Care should be taken to ensure the
orientation of the insertion handle and aiming arm is
not altered.
The 6.0 mm/10.0 mm stepped cannulated drill bit must be
used to prepare a path for the full length of the shaft of the
screw. The stepped drill bit must be used after the cortex has
been opened using the 11.0 mm tapered drill bit.
Pass the drill stop over the back end of the stepped drill bit
and adjust the setting to the measured screw length. Pass
the drill bit over the guide wire, through the blade guide
sleeve and advance under power. Drill to the stop.
