Abstract

The present invention relates to an orthopedic fastener for fixing an implant, suture, or tissue to a bone. The fastener comprises a blind rivet and a closing element. The blind rivet includes a head at a proximal end, a shank connected to the head, and an anchoring portion near a distal end. A bore extends through the head and shank from the proximal end to the distal end and the bore has a polygonal cross-section 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 polygonal cross-section flaring along the longitudinal axis toward the closing element distal end. The anchoring portion of the blind rivet severs into a plurality of anchoring legs when the closing element is pulled in the bore toward the blind rivet proximal end to thereby prevent rotation of the fastener.
