1. A bone plate with a lower surface, an upper surface, a maximum thickness T measured between the lower and upper surfaces, a left lateral surface, a right lateral surface, a longitudinal axis and a plurality of plate holes running from the lower surface to the upper surface, wherein the bone plate further comprises a slot with an opening in the lower surface, wherein the slot extends through the bone plate from the left lateral surface to the right lateral surface and has a width W measured in a plane parallel to the longitudinal axis and a central plane between the left lateral surface and the right lateral surface, and wherein:
(i) the slot includes an inner surface that defines a hollow space extending through the bone plate from the left lateral surface to the right lateral surface through which a straight line is passable without contacting the inner surface of the slot; and
(ii) the slot comprises an undercut feature limiting the opening of the slot when the bone plate is bent longitudinally in a direction aimed at widening the slot.
