Abstract
A compression fastener system includes an elongate generally rigid coupling component, a toggle anchor at the distal end of the coupling component that can pivot about 90 degrees between inline and out of line with the coupling component, and a generally cylindrical collet that is engageable with a surface of the coupling component, and having two or more legs that splay upon passage of the coupling component through the collet, at least one leg having a cutting edge along at least a portion of its length that can engage with an adjacent rigid element, such as bone, to fix the rigid coupling component, toggle anchor and collet assembly into compression with the rigid element.
