Claim:
A bone fixation system for aiding reduction of a fractured bone, said bone fixation system comprising: a bone pin adapted to support portions of the fractured bone, said bone pin having a first prong, a second prong, a central portion, and a mid-longitudinal axis extending through said central portion and between said first and second prongs, said central portion including a first end, a second end, and at least one arcuate portion, said at least one arcuate portion defining at least in part at least one opening for receiving at least one bone screw, said at least one arcuate portion being adapted to engage a portion of said at least one bone screw, said at least one arcuate portion extending around at least 180 degrees and having a first radius, said at least one opening comprising a first opening and a second opening, each of said first and second openings defined by portions of two of a first arcuate portion, a second arcuate portion, and a third arcuate portion of said at least one arcuate portion, said first opening adapted to receive a first bone screw of said at least one bone screw and said second opening adapted to receive a second bone screw of said at least one bone screw, said first opening and said second openings each having a center, said centers of said first and second openings being provided on opposite sides of the mid-longitudinal axis of said bone pin, said first prong extending outwardly from said first end of said central portion and said second prong extending outwardly from said second end of said central portion, said first and second prongs being symmetrical about a first plane extending through the mid-longitudinal axis and bisecting said central portion, said first and second prongs each including a substantially straight portion and a bone engaging portion adapted to contact the portions of the fractured bone; and said at least one bone screw having a proximal end, a distal end opposite said proximal end, a head portion proximate said proximal end, and a shaft portion extending from said head portion to said distal end, said head portion having a first surface oriented toward said distal end, said first surface being adapted to engage said at least one arcuate portion of said bone pin, said head portion having a second radius, and said shaft portion having a third radius adjacent said head portion, wherein said first radius of said at least one arcuate portion is less than said second radius and greater than said third radius.
