Abstract

A bone anchor is described having pre-attached suture material. After insertion, lateral wings can be deployed on the bone anchor to prevent anchor pull-out. The suture may be attached at the tip of the anchor by tying it to a wire hook secured in a cavity in the anchor tip. The anchor may be inserted and deployed using an anchor inserter that is configured to apply an axial force to the anchor, thereby deforming the anchor to form the lateral wings.
