Abstract
A bone plate includes a plate body defining an interior surface that defines a combination hole that includes intersecting locking and compression holes that each extend between outer and bone-facing surfaces of the plate body. A central axis of the compression hole is spaced from a central axis of the locking hole in an offset direction. A locking surface of the plate body defines the locking hole and at least one locking structure therein. A compression surface of the plate body defines the compression hole. An intersection boundary between the locking and compression surfaces is configured to translate the bone plate in the offset direction during contact between the intersection boundary and a head of a compression screw as it advances within the combination hole along an insertion axis offset from the central axis of the locking hole at an offset distance in a direction having a directional component in the offset direction.
