Claim 12:
13. A bone plate, comprising:
a plate body that defines an outer surface, a bone-facing surface opposite the outer surface, and a combination hole comprising a locking hole and a compression hole that intersect one another and each extending from the outer surface to the bone-facing surface, wherein the locking hole and the compression hole extend away from each other along a longitudinal axis,
the plate body further defining 1) a locking surface that defines the locking hole, and 2) a second surface that defines the compression hole;
wherein the locking surface further defines:
a plurality of columns sequentially located about a central axis of the locking hole in a polygonal pattern;
a plurality of recesses located, respectively, between at least some of the columns; and
plate threads that traverse each of the columns, wherein crests of the plate threads extend linearly from a first side of each column to a second side of each column; and

wherein:
the plate body defines an intersection boundary between the locking surface and the second surface, and a first portion of the intersection boundary on a first side of the longitudinal axis is separated from a second portion of the intersection boundary on a second side of the longitudinal axis by a gap that is open to the locking hole and the compression hole;
the longitudinal axis intersects a first column of the plurality of columns and extends centrally through the gap; and
the plurality of columns further comprises second and third columns, wherein the second and third columns are substantially equidistantly spaced from the longitudinal axis with respect to a lateral direction perpendicular to the longitudinal axis.
