1. A system for perfecting bone contact in bone fixation by compressing the bone parts against each other and moving them a total bone displacement distance, comprising:
a rail comprising a fork with elongated handle, said handle having a first plurality of holes on for fastening to a first part of a fractured bone, said fork comprising two parallel plates connected to said handle, positioned a first distance apart, and a second plate with a proximal and a distal end and with a second plurality of holes on a distal end for fastening to a second part of said fractured bone on the distal end; wherein said parallel plates of said fork extend outward from the fractured edge of the first part of said fractured bone a first extended region, and said second plate, affixed on the distal end of said second plate to said second part of said fractured bone such that said proximal end of said second plate extends outward from the fracture edge of the second part of said fractured bone a second extended region; a first plurality of conically-shaped holes made into each of said parallel plates of said fork, identically and perfectly aligned, such that the holes being spaced a first pitch apart, and a second plurality of conically-shaped holes made into the second plate, spaced a second pitch apart; wherein the first pitch is different from the second pitch and that the width of said second plate, said width as related to insertion of second plate between said two parallel plates of said fork, is less than said first distance; wherein said second plate is slidably positioned between said two parallel plates of said fork such that said first extended region and second extended regions at least partially overlap, to approach said first part and said second part of said fractured bone to each other; and wherein said overlapping is performed by creating a desired alignment position, comprising aligning the fork with said second plate such that at least one of the holes on the first plurality of conically-shaped holes, that is the first target hole, is offset with at least one of the holes on the second plurality of conically-shaped holes that is the second target hole, and the amount of offset is equal to or a fraction of said total bone displacement needed, and a first conically shaped wedge of a plurality of conically shaped wedges is passed through said first target hole and pushed toward insertion into said second target hole such that said offset is eliminated by pushing said second bone part toward the first bone part. |
