| 1. A system for guiding bone anchors, the system comprising:
a guide wire
an anchor comprising:
a shank having a proximal end and a distal tip, wherein the shank has an offset bore which is adapted to allow the guide wire
to slide through the bore, wherein the bore extends from the distal tip of the shank to a side surface of the shank, and wherein
the shank does not have a bore which causes a cannulation through the entire length of the anchor; and
a head coupled to a proximal end of the shank;
a dilator having a longitudinal slot where the longitudinal slot allows the guide wire to extend through the longitudinal
slot when the anchor is positioned within the dilator; and
a driving device which is adapted to engage the head of the anchor.
