1. A fixation system for coupling a first bone and a second bone together, said fixation system comprising:
a first fixation screw having a tapered external surface configured to engage the first bone, the first fixation screw including a first cavity at least partially including a first tapered mating recess formed in a wide end of the first fixation screw, wherein the wide end of the first fixation screw is secured to a first body portion of an interconnect and is contiguous with a narrow end of the first fixation screw, wherein the first cavity further comprises a keyed region configured to rotate the first fixation screw into the first bone;
a second fixation screw having a tapered external surface configured to engage the second bone, the second fixation screw including a second cavity at least partially including a second tapered mating recess formed in a wide end of the second fixation screw, wherein the wide end of the second fixation screw is secured to a second body portion of the interconnect and is contiguous with a narrow of the second fixation screw, wherein the second cavity further comprises a keyed region configured to rotate the second fixation screw into the second bone; and
the interconnect comprising a first tapered surface and a second tapered surface disposed at generally opposite ends, said first tapered surface and said second tapered surface are configured to frictionally engage said first tapered mating recess and said second tapered mating recess of said first fixation screw and said second fixation screw, respectively, to form frictional interference connections therebetween; and wherein the interconnect also including a flexible region formed between the first tapered surface and the second tapered surface to enable the first fixation screw to bend with respect to the second fixation screw.
