Claim 0:
1. A bone plate, comprising:
a plate body that defines a combination hole comprising a locking hole and a compression hole that intersect one another and each extends from an outer surface of the plate body to a bone-facing surface of the plate body, 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, 2) a second surface that defines the compression hole, and 3) interface edges along an intersection boundary between the locking surface and the second surface;
wherein the locking surface further defines:
first, second, and third columns sequentially located about a central axis of the locking hole, each column having a first side and a second side;
a first recess extending from the second side of the first column to the first side of the second column;
an additional recess extending from the second side of the third column to the first side of the first column;
a transition zone between the first side of the second column and the second side of the third column, wherein the locking surface in the transition zone is elongated and extends to the intersection boundary; and
plate threads that traverse each of the columns and at least portions of the first recess, the additional recess, and the transition zone, wherein crests of the plate threads extend linearly from the first side to the second side of each column.
