Step 13: Verify Central Guide
Wire Placement
• Place the guide wire in the centre of the
humeral head
• This plate position will reduce the risk of
subacromial impingement
Step 15: Manually Drill for Subchondral
Support Pegs
• With the 4.0 mm drill attached to the driver
handle, advance the drill, through the drill
guide until resistance from subchondral bone
is felt
• This will ensure that the peg engages
subchondral bone for optimal fixation
Tips: when drilling for smooth pegs use FDB40L
(Drill Bit Fast 4.0 mm Long).
When drilling for partially threaded pegs use
FDS40 (Drill Bit Fast 4.0 mm Step).
Step 14: Drill Cortex Through
F.A.S.T. Guide
• Using the short 4.0mm drill (FDB40S), drill
through the F.A.S.T. Guide and perforate
the cortex
• This drill has a stop that will only
allow it to penetrate the
near cortex
• If re-drilling is required after F.A.S.T. Guide
removal, thread the drill guide (DRGSH) into
the desired peg hole and drill on power using
DB40S (Drill Bit Short 4.0 mm)
Tips: bending the central guide wire and
rotating it out of the way will ease the
attachment of the drill guide to the plate.
Other K-Wire holes can be used to provisionally
fix the plate to the bone.
Step 16: Verify Drill Depth
• Once resistance is felt, fluoro imaging should
verify that the tip of the manual drill is close to
subchondral bone
• Care should be taken not to penetrate
subchondral bone
Tips: the depth gauges have a bias built in that
will reduce the measured depth by 2.5 mm. If
peg to subchondral bone contact is desired,
add 2.5 mm to the depth gauge.
Depths can be Gauged from the
manual drill or the sleeveless depth
gauge. Both can be read through
either the F.A.S.T. Guide or through
the drill guide, using the appropriate
calibrated scale.
