The LARGE QWIX® screws and instrumentation
are color coded :
Yellow for 5.5 mm
diameter screws
Purple for 7.5 mm diameter screws
Positioning Guide
Pin
A 1.6 or 2.5mm K-wire should be
introduced to achieve temporary fixation
and maintain alignment.
A drill guide and soft tissue protector
is offered to prevent entrapment of
the soft tissues during insertion
(figure 1).
(Note: The use of x-rays is recommended
to check the positioning and depth of
the K-wire.)
Screw Length Measurement
The measuring device is graduated
in accordance with the various K-wires
included within the set. The measuring
device should be placed along the
K-wire such that the tip is in contact
with the surgical site. The appropriate
screw length is determined directly
from the measuring device on the side
marked. (K-wire 200mm/ K-wire 250mm)
(figure 2)
(Note: The measurement taken from
the measuring device is directly related
to the positioning of the guide pin
and therefore, is not considered accurate
unless the guide pin is positioned
correctly. The surgeon may decide
to add or deduct a few millimeters
depending on the position of the guide
pin and the desire to obtain mono
or bi-cortical fixation.)
