Abstract
A bone anchor having a rivet having a proximal end and a head distal to an elongate body, a sleeve having an internal channel for slidably receiving the body, and an expansion nut having a channel therethrough for slidably receiving said body, proximal of said sleeve is provided. The sleeve further has a shoulder provided within the internal channel in the region of the proximal end for engaging the expansion nut. The rivet, sleeve and expansion nut are arranged such that movement of the rivet from a first position to a second position causes the sleeve to cam over the rivet head and expansion nut until said expansion nut engages said shoulder, forcing the sleeve to expand into a wall of a bone hole.
