Abstract

A bone anchor (10) includes a screw portion (12) configured to penetrate a bone. The screw portion includes a retention thread (18) extending at least part of a length of the screw portion and a tip (22) at a first end of the screw portion. The bone anchor includes a protrusion (24) adjacent a second end of the screw portion. The second end is opposite the first end of the screw portion. The protrusion comprises a plurality of external sides forming a shape and a rounded interior surface (30) enclosing a protrusion recess (26). The rounded interior surface includes a recess thread (31) configured to retain a component at least partially in the protrusion recess. The protrusion has a maximum width that is less than a maximum diameter of the screw portion such that a shoulder is formed where the protrusion meets the second end of the screw portion.
