Claim 12:
13. A surgical method, comprising:
making an incision to a target site within a patient;
advancing a bone anchor assembly through the incision, the bone anchor assembly being coupled to an inserter instrument having:
an elongate body that extends from a proximal end to a distal end and defines a central axial lumen therebetween;
an engagement portion formed at the distal end of the elongate body that is configured to engage a bone anchor assembly;
a stylus having a guide projection that is configured to be received through the central axial lumen and extend through the bone anchor assembly to be axially translatable between at least a first position in which a distal end of the guide projection protrudes from a distal tip of the bone anchor assembly and a second position in which the distal end of the guide projection does not protrude from the distal tip of the bone anchor assembly; and
a collar disposed around the elongate body that moves relative to the elongate body to engage the elongate body and actuate the stylus to translate axially, the collar being disposed distal to a proximal-most end of the stylus;

positioning the bone anchor assembly at the target site such that a distal end of the guide projection is positioned against a bone surface at the target site;
distally tapping the inserter instrument to dock the guide projection in the bone surface; and
rotating the inserter instrument to advance the bone anchor assembly into the bone.
