THE PRESENT INVENTION RELATES TO AN ORTHOPEDIC FASTENER FOR FIXING AN IMPLANT, SUTURE, OR TISSUE TO A BONE. THE FASTENER COMPRISES A BLIND RIVET (1) AND A CLOSING ELEMENT (2). THE BLIND RIVET (1) INCLUDES A HEAD (19) AT A PROXIMAL END (32), A SHANK (8) CONNECTED TO THE HEAD (19), AND AN ANCHORING PORTION (9) NEAR A DISTAL END (12). A BORE (4) EXTENDS THROUGH THE HEAD AND SHANK FROM THE PROXIMAL END TO THE DISTAL END AND THE BORE HAS A POLYGONAL CROSS-SECTION (5) THROUGH THE ANCHORING PORTION. THE CLOSING ELEMENT HAS A BODY WITH AN OUTER SURFACE AND IS CONFIGURED AND DIMENSIONED TO BE RECEIVED IN THE ANCHORING PORTION. THE OUTER SURFACE OF AT LEAST A PORTION OF THE CLOSING ELEMENT DISTAL END HAS A POLYGONALCROSS-SECTION FLARING ALONG THE LONGITUDINAL AXIS TOWARD THE CLOSING ELEMENT DISTAL END. THE ANCHORING PORTION (9) OF THE BLIND RIVET (1) SEVERS INTO A PLURALITY OF ANCHORING LEGS (13) WHEN THE CLOSING ELEMENT (2) IS PULLED IN THE BORE (4) TOWARD THE BLIND RIVET PROXIMAL END TO THEREBY PREVENT ROTATION OF THE FASTENER.FIG. 1 |
