A bone fixation device, comprising: a first element extending from a first head at a first end to a first shaft (112, 114) at a second end along a first central longitudinal axis and having a first channel extending therethrough, the first head extending transverse to the first shaft (112, 114) providing a first shoulder which, in an operative configuration, rests against a portion of bone adjacent to a first hole through which the first shaft (112, 114) is inserted to define a maximum extent to which the first element may be inserted into the first hole; and a second element including a second shaft extending along a second central longitudinal axis from a third end to a second head at a fourth end thereof and having a second channel extending therethrough, the second head extending transverse to the second shaft providing 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 extent to which the second element may be inserted into the second hole, characterized in that the second channel is dimensioned to slidably receive the first shaft (112, 114) therein; and in that the bone fixation device further comprises a tensioning element insertable through the first and second channels (116, 126), the tensioning element including a first end sized to prevent the first end from entering one of the first and second channels (116, 126) so that, tension applied at a second end of the tensioning element imparts a compressive force to the first and second elements (102, 104) and, consequently to a bone into which the first and second elements (102, 104) are inserted. a first element extending from a first head at a first end to a first shaft (112, 114) at a second end along a first central longitudinal axis and having a first channel extending therethrough, the first head extending transverse to the first shaft (112, 114) providing a first shoulder which, in an operative configuration, rests against a portion of bone adjacent to a first hole through which the first shaft (112, 114) is inserted to define a maximum extent to which the first element may be inserted into the first hole; and a second element including a second shaft extending along a second central longitudinal axis from a third end to a second head at a fourth end thereof and having a second channel extending therethrough, the second head extending transverse to the second shaft providing 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 extent to which the second element may be inserted into the second hole, characterized in that the second channel is dimensioned to slidably receive the first shaft (112, 114) therein; and in that the bone fixation device further comprises a tensioning element insertable through the first and second channels (116, 126), the tensioning element including a first end sized to prevent the first end from entering one of the first and second channels (116, 126) so that, tension applied at a second end of the tensioning element imparts a compressive force to the first and second elements (102, 104) and, consequently to a bone into which the first and second elements (102, 104) are inserted.
