SUTURE ANCHOR WITH ENHANCED FIXATION

摘要

A suture anchor comprises an anchor body having a proximal end, a distal end, a longitudinal axis and bone engaging external threads oriented for rotation about the longitudinal axis. A longitudinal axial bore extends into the body from its proximal end and at least one lateral passage passes from the axial bore outwardly through the body. A suture attachment element disposed within the axial bore has at least one protruding member having a first position disposed within the axial bore and a second position protruding outwardly from the anchor body through the at least one lateral passage. The protruding member inhibits rotation of the suture anchor body within the bone.
