Abstract
A bone anchor includes a shank having a longitudinal axis, a core, a tip at one end of the core, and a thread forming a helix that extends around the core with a lower flank directed towards the tip and an upper flank directed away from the tip. A recess in a first turn of the thread forms a cutting structure, the recess being defined by first and second surfaces directly connected to one another at an angle. The first and second surfaces are spaced apart from every other turn of the thread above or below the first turn. A majority of the first surface is positioned higher axially than and circumferentially aligned with part of the second surface. At least one of the first or second surfaces extends circumferentially around the shank by a greater distance than an axial height of the at least one surface.
