Locate pedicles and use the awl to perforate the cortex.
Use the probe to open the pedicle canal. Using radio-
graphic imaging, confirm pedicle location, orientation
and depth by inserting the probe. When selecting the
appropriate length screw, use the markings on the probe
to determine the pedicle depth.
All MATRIX pedicle screws are self-tapping; however, if
tapping is preferred, use the appropriate tap and tap
handle.
