1. A bone plate including:
a plate body that defines a bone-facing body surface configured to face a bone and an outer body surface opposite the bone-facing body surface, wherein:
the bone plate defines a first aperture that extends through the plate body from the outer body surface to the bone-facing body surface along a central first aperture axis,
the plate body defines a first direction, a second direction perpendicular to the first direction, and a third direction opposite the second direction and perpendicular to the first direction, and
the bone plate defines a plurality of fixation holes that extend through the plate body from the outer body surface to the bone-facing body surface along respective central axes and are each configured to receive a respective bone anchor, wherein the first aperture is disposed between first and second ones of the fixation holes with respect to the first direction, such that a first straight line that passes through the first aperture and is oriented along the first direction also passes through the first and second ones of the fixation holes, and
the plurality of fixation holes further includes third and fourth ones of the plurality of fixation holes that are offset in their respective entireties from the first aperture in the second direction, such that 1) a second straight line that is oriented along the first direction and extends through the third one of the plurality of fixation holes also passes through the fourth one of the plurality of fixation holes, 2) no straight line that is oriented in the first direction that passes through the third and fourth ones of the plurality of fixation holes also passes through the first aperture, and 3) a central axis of the third one of the plurality of fixation holes is disposed between respective central axes of the first and second ones of the plurality of fixation holes with respect to the first direction;
a first leg that extends from the plate body along the third direction at a location aligned with the first aperture along the third direction, wherein the first leg defines a respective first fixation hole that is configured to receive a first respective bone anchor; and a second leg that extends from the plate body and defines a respective second fixation hole that is configured to receive a second respective bone anchor, wherein the first and second legs are the only legs that extend from the plate body.
