Abstract
Examples of the invention relate to methods, implants, and instruments for compressing first and second bone portions or a bone portion and an implant together.
Claims18
A bone fastener comprising:
- an insertion axis;
- a body with a generally planar configuration having opposed planar sides spaced apart a body thickness, the body extending between a distal body leading end and a proximal body trailing end, the body leading end and the body trailing end being spaced from one another longitudinally relative to the insertion axis, the opposed planar sides converging toward the body trailing end to define a trailing edge having a trailing edge thickness less than the body thickness;
- 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.

A bone fastener construct stabilizing a first bone portion relative to a second abutting bone portion, the construct comprising:
- an insertion axis along which the fastener moves as it is inserted into or removed from a bone;
- a body and an aperture through the body, the aperture having a length and a width, the aperture length being greater than the aperture width, the aperture length being oriented transverse to the insertion axis;
- 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 equal to or 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 at least part of the first elongate inboard surface diverges from at least part of the second elongate inboard surface;
- and
- an elongate fixation member positioned within the aperture and engaging at least one of the first and second bone portions.

A bone fastener construct stabilizing a first bone portion relative to a second abutting bone portion, the construct comprising:
- an insertion axis along which the fastener moves as it is inserted into or removed from a bone;
- a body and an aperture through the body, the aperture having a length and a width, the aperture length being greater than the aperture width, the aperture length being oriented transverse to the insertion axis;
- 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 equal to or 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 at least part of the first elongate inboard surface diverges from at least part of the second elongate inboard surface;
- and
- a guide having a guide axis, the guide being mounted to the fastener in rotating relationship, the guide being rotatable between a plurality of positions in which the guide axis intersects the aperture.
