ABSTRACT:
A bone screw comprises a threaded shank having an axis of rotation. A head is integral with the shank, and the head includes a surface disposed generally normal to the axis. A plurality of drive receivers are disposed about the surface wholly remote from the axis. Each of the drive receivers is adapted for engagement with a cooperating driver element of a rotary driver so that the head and thereby the shank may be rotated about the axis.
