Abstract

A bone plate having a first, bone-facing surface and an opposing second surface has an elongate shaft portion and a head portion that is shorter and wider in comparison thereto, with at least one through hole extending through the bone plate from the first surface to the second surface in the shaft portion. The through hole comprises a variable-angle portion with a hole axis configured to receive a threaded head of a locking screw therein at a desired angle within a permitted range of angulation relative to the hole axis. The second surface has at least one depression which extends therein along a portion of the second surface between the side wall and the through hole, the depression extending about a periphery of the through hole.
