Реферат: A bone plate has an outer surface, a bone-facing surface opposite the outer surface, and an interior surface that defines a hole extending from the outer surface to the bone-facing surface along a central hole axis. The interior surface further defines a ramp that extends from the outer surface toward the bone-facing surface and plate threads that extend from the ramp toward the bone-facing surface and are configured for optional locking engagement with external threads on a first head of a locking bone fixation member. The interior surface further defines a contact profile in a reference plane that extends along the central hole axis. The contact profile is defined at least by the ramp and is spaced from the central hole axis in an offset direction perpendicular to the central hole axis. The contact profile is configured to translate the bone plate in the offset direction responsive to contact with an exterior surface of a second head of a compression bone fixation member as the second head advances within the hole along an insertion axis that is offset from the central hole axis in the offset direction.
