Abstract: A suture anchor, or rivet, for fixing one end of a suture in a bone has a forward and formed of a plurality of truncated cones positioned in line behind a cone with a cylindrical member extending from the last truncated cone forming the rear end; a plurality of spiral grooves extend through the outer surfaces of the truncated cone and cone for spirally inserting the anchor, the spiral grooves forming serrations therebetween to prevent the suture anchor from being withdrawn from a bone into which it has been driven. An impact tool is used having a hole in the end to receive and engage the cylindrical member of the suture anchor.
