Gamma3 Trochanteric Nail 180 - Stryker

Operative Technique
3mm Guide Wire
or 3.2mm K-Wire
One Step Conical Reamer
Multi Hole Trocar
Reamer Sleeve
Alternative 2:
One Step Conical Reamer
The One Step Conical Reamer is an
optional instrument and has been developed
to provide surgeons with
another option to prepare the
proxi-mal canal of the trochanter
using only one drilling step.
When the Gamma3 Nail 180 is used,
reaming of the subtrochanteric and
diaphyseal region of the femoral cavity
may not be required, particularly in
elderly patients with wide medullary
canals.

After skin incision and positioning
of the Guide Wire as described above,
the Trocar or Multi Hole Trocar
is inserted into the Reamer Sleeve
to protect the soft tissue during
insertion. Push the Trocar (use center
hole, if Multi Hole Trocar is used) and
Sleeve Assembly down over the 3mm
Guide Wire to the tip of the trochanter
(Fig. 28 and 29).
Entry Point Optimization
The Entry Point can also be made
without using the awl. A 3.2mm
K-Wire is placed through the tip of the
trochanter.
K-Wire
If you find that the K-Wire is not positioned
in the optimal position, it may
easily be corrected using a second
K-Wire in combination with the
Multi Hole Trocar.
The Multi Hole Trocar has a special
design for more precise insertion. In
addition to the central hole, 4 other
holes are located eccentrically at
different distances from the center
(Fig. 29) to easily revise insertion
of the guiding K-Wire in the proper
position (Entry Point).
