1. A bone fixation device, comprising:
a first element including a first head and a first shaft extending along a first central axis from a first end connected to the first head to a second end, the first element including a first channel extending therethrough, the first head extending transverse to the first shaft to provide a first shoulder which, in an operative configuration, rests against a portion of bone adjacent to a first hole through which the first shaft is inserted to define a maximum extent to which the first element may be inserted into the first hole, the first head including a first opening extending therethrough adjacent to the first channel; a second element including a second head and a second shaft extending along a second central axis from a first end connected to the second head to a second end, the second element including a second channel extending therethrough, the second head extending transverse to the second shaft to provide a second shoulder which, in an operative configuration, rests against a portion of bone adjacent to a second hole through which the second shaft is inserted to define a maximum extend to which the second element may be inserted into the second hole, the second channel sized and shaped to receive the first shaft therein; and a tensioning element insertable through the first opening and through the first and second channels, the tensioning element including a first end sized to prevent the first end from passing through the first opening so that, tension applied at a second end of the tensioning element applies a compressive force to a bone through which the first and second elements are inserted. |
