Driver through the base of the second metacarpal and can be extended into the first cortex of the third metacarpal, if desired. Although the Fixator Pins have a self-drilling feature, a 3.2 mm Pilot Drill is provided if predrilling is needed due to dense bone. Rotate the 25 mm Fixator Drill Guide 180 degrees so the short cannula is placed over the previously inserted Fixator Pin. Making sure the longer cannula is centered on the bone, predrill and insert the second Fixator Pin. Advance the Fixator Pins until two to three threads have extended through the far cortex.
Note: The 25 mm Fixator Drill Guide assures the Fixator Pins are placed parallel.
