Abstract:
A cable anchoring apparatus comprising:a screw member for being inserted into a bone portion and having a central axis thereof, a shank wall of the screw member having spaced proximal distal ends and an axial bore extending therethrough; a flexible cable having an enlarged end portion that secures the cable against being pulled through the bore; a small diameter intermediate section of the bore through which the cable extends and sized smaller than the cable enlarged end portion; a larger diameter section of the bore at the distal end of the shank wall in which the cable enlarged end portion is held; and an elongate tapering portion of the bore intermediate section that gradually tapers radially outwardly relative to the central axis as the tapering portion extends toward the proximal end of the shank wall to allow the cable to engage along the tapering portion to begin to flex in a direction offset from the screw axis prior to being bent about the shank wall proximal end as the cable exits the bore; wherein the axial bore includes an enlarged driver section at the proximate end of the shank immediately adjacent to the tapering portion.
