Abstract
Surgical instruments and methods for implanted bone anchor assemblies into bone are disclosed herein. In one exemplary embodiment, an instrument is provided having an anchor drive assembly and a stylet assembly. The anchor drive assembly can have a first handle and an elongate shaft having a distal tip configured to couple to a bone anchor assembly. The stylet assembly can have a second handle and a stylet extending through the elongate shaft. The instrument can have a disengaged position and an engaged position such that rotation of the first handle is effective to drive the bone anchor assembly into bone only when the instrument is in the engaged position, and rotation of the second handle is effective to cause axial translation of the stylet relative to the elongate shaft.
