A suture anchor, self-retaining bone screw and method of making and using them are disclosed. The suture anchor includes a track within which a suture may be anchored. The suture anchor track may be incorporated underneath the head of a bone screw in general alignment with a slot used to drive the bone screw, so that the track is accessible through the slot. In operation, suture is slid down into the slot and over and up into the track. The self-retaining screw includes at least one spring arm that provides a locking force when engaged with a driver. A method of making the anchor track and self-retaining component is also disclosed. The method comprises positioning a screw blank and using an EDM process to cut a slot and an internal track into the head portion of the screw blank.
