1. A surgical fastener assembly for coupling first and second bone portions across a fracture therebetween, said fastener assembly comprising:

  • an elongated anchor endwise insertable within the first bone portion such that a first end portion of said anchor is disposed on one side of the fracture while a second end portion of the anchor is disposed on an opposite side of the fracture, wherein a threaded elongated bore extends within said anchor;

    a guide adapted to be fixedly secured to the second bone portion, with a projection on said guide being guided by and along the second end portion of said anchor;

    a cannulated fastener including an enlarged head portion and an externally threaded shank portion with an elongated bore extending through said head and shank portions and opening at opposite ends of said fastener, wherein, in an operative position, the shank portion of said fastener extends into threaded engagement with said anchor while the head portion of said fastener operably engages with said guide such that rotation of said fastener draws the first and second bone portions into compressive relationship relative to each other; and

    a retainer positioned within said bore extending within said anchor, the retainer being threadably associated with the second end of said anchor and positionable relative to said fastener for releasably locking said fastener to prevent axial displacement of said guide in a direction away from said anchor.
