Gamma3 Trochanteric Nail 180 - Stryker

Operative Technique
To verify the correct position of the
Set Screw, try to turn the Lag Screwdriver
gently clockwise and counterclockwise.
If it is not possible to turn
the Lag Screwdriver, the Set Screw is
engaged in one of the grooves. If the
Lag Screw Driver still moves, recorrect
the handle position and tighten the Set
Screw again until it engages in one of
the four grooves.
After slightly tightening the Set
Screw it should then be unscrewed
by one quarter (¼) of a turn, until
a small play can be felt at the Lag
Screwdriver. This ensures a free
sliding of the Lag Screw.

Set Screw insertion
Make sure that the Set Screw is still
engaged in the groove by checking that
it is still not possible to turn the Lag
Screw with the Lag Screwdriver.
Note:
Do not unscrew the Set Screw more
than ¼ of a turn.
As an alternative, the Set Screw can be
inserted using Gamma3 Closed Tube
Clip (see next page).
If distal locking is not indicated, the
End Cap should be assembled to the
nail end to prevent bone ingrowth.
Leaving the Lag Screwdriver in
place, the Nail Holding Screw is now
removed using the ball tip Screw
Driver or Universal Socket Wrench
and turning it counter clockwise.
Insert the End Cap (size 0) using
the Socket Wrench or the Ball Tip
Screwdriver. The End Cap should be
tightened slightly.

Please see chapter “End Cap
Insertion”.
Alternatively the End Cap could also
be inserted free hand after removal of
the Target Device.
