Step 8 – Insertion of the Hansson
Pin and Activation of the Hook
Insert the Hansson Pin with the
Introducer Assembly into the femoral
channel which has been pre-drilled.
Ensure that the pin is fully inserted.
Use fluoroscopy to verify the position
of the Hansson Pin. (Fig 15).
There is an etched line on the handle
of the Outer Introducer which
indicates the Inner Pin’s point of exit.
Verify that this guide line is in alignment
with the femoral shaft. (Fig. 16).
Thus the hook will be extruded in
the superior direction as demonstrated
in figure 17.
Insert the tip of the Introducer Handle
through the hole in the Inner Introducer.
Maintain both the Outer and Inner
Introducers in position.
Turn the Introducer Handle clockwise
whilst gently pushing medially on the
introducer assembly. Continue turning
the Introducer Handle to completely
deploy the hook using biplanar
fluoroscopy. A mechanical stop is
provided by the Inner Introducer
(Fig. 17).
