Instruments
357.369 Guide Sleeve for Helical Blade for TFN
357.403 Reamer
6.0/10.0 mm, cannulated,
length 435 mm,
for Quick Coupling No. 511.760
357.404 Drill Bit
11.0 mm, conical, cannulated,
length 280 mm,
for Quick Coupling No. 511.760
357.405 Fixation Sleeve
Remove the drill sleeve from the blade guide sleeve. Place
the 11.0 mm 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 head element insertion. If the guide wire falls out
or comes out when the drill bit is removed, it may be left out
for head element insertion. Care should be taken to ensure
the orientation of the insertion handle and aiming arm is not
altered.
For dense bone, the 6.0 mm / 10.0 mm cannulated reamer
should be used to prepare a path for the full length of the
shaft of the head element. The reamer should be used only
after the cortex has been opened using the 11.0 mm drill bit.
Pass the fixation sleeve over the back end of the reamer and
adjust the setting to the measured head element length.
Pass the reamer over the guide wire, through the blade
guide sleeve and advance under power. Drill to the stop.
