FOUR FAST, EASY INSERTION TECHNIQUES
Once
the plates have been rejuvenated in a warm bath, they remain
malleable at room temperature for several hours, during which
time modifications can still be made.
The
unique Inion screw design allows the surgeon to choose a preferred
method of insertion.
›
1) Inion Tacker
|
|
1)
Insert the screw-ring into loader. |
|
|
2)
Cock the Tacker™
by turning the handle clockwice. |
|
|
3)
Insert the chosen screw into the Tacker by pushing the
loading button. |
|
|
4)
The screw is held at the tip of the piston and is retracted
inside the cannula by a gentle push. |
|
|
|
|
|
5)
Press the cannula firmly against the screw hole and
fire the screw into the aligned drill hole.

2) Drill-Tap
|
|
1)
Drill the hole with a self tapping drill bit, using
slow rpm. drill (max 200 rmp). Verify that the power
console for the drill is set to very low rmp, and ensure
that the drill bit is inserted before the drill stop
contacts the plate or bone as appropriate. Failure to
do so will strip the hole. Irrigate profusely while
drilling to minimize possible necrosis.
2)
Insert screw with a screwdriver. Do not overtighten.

3) Self Tapping Screw
Procedure for thin cortex (less than 2 mm)
|
|
1)
Drill a hole.
2)
Insert screw with a screwdriver. Do not overtighten.
|
›
4) Manual Tap
|
|
1)
Drill a pilot hole.
2)
Create threads using manual tap. Remove any bone dust
and debris to ensure optimal implant contact with the
bone surface.
3)
Insert screw with a screwdriver, allowing the screw
threads to follow the tapped threads. Take care not
to apply excessive insertion force or torque.
