主权项

1. A bone fastener comprising:
an insertion axis; a body; a first leg connected to the body, the first leg having a first elongate inboard surface facing the insertion axis and extending from a first leg leading end to a first leg trailing end, the first elongate inboard surface being spaced from the insertion axis a first leading distance at the leading end and the first elongate inboard surface being spaced from the insertion axis a first trailing distance at the trailing end, the first leading distance being greater than the first trailing distance; and a second leg connected to the body, the second leg having a second elongate inboard surface facing the insertion axis and extending from a second leg leading end to a second leg trailing end, the second elongate inboard surface being spaced from the insertion axis a second leading distance at the leading end and the second elongate inboard surface being spaced from the insertion axis a second trailing distance at the trailing end, the second leading distance being equal to or greater than the second trailing distance; wherein the first leg has a first elongate outboard surface facing away from the insertion axis and extending at least half of the distance from the first leg leading end to the first leg trailing end and the second leg has a second elongate outboard surface facing away from the insertion axis and extending at least half of the distance from the first leg leading end to the first leg trailing end, the first and second elongate outboard surfaces each being parallel to the insertion axis.
