Abstract:
1. A bone plate comprising: at least one plate hole whose hole axis runs obliquely relative to an underside of the plate, the hole axis having an elevation angle (ε) relative to a plane of the underside of the plate which is different from 90° , and in which an upper face of the plate runs at least partially non-parallel to the underside of the plate at least in the area around the plate hole, and runs at a right angle to the hole axis, wherein the plate hole is configured such that a bone screw, when screwed into the plate hole, is locked in the plate hole at an angle selected from a predetermined angular range around the elevation angle (ε) of the hole axis by only cooperation of the plate hole with the bone screw, and without additional auxiliary means, wherein an axis of the bone screw when screwed-in may assume any selected angle within the predetermined angular range; the plate further including an elevation formed on an upper face of the plate in the area around the respective plate hole where the axis of the plate hole runs obliquely relative to the underside of the plate; and wherein the plate is not sufficiently thick to permit a head of the bone screw to be completely countersunk, wherein the elevation is configured to permit the head of the bone screw to be completely countersunk in the respective plate hole when screwed-in at a selected angle within the predetermined angular range, and wherein the selected angle is different from the elevation angle (ε) of the axis of the plate hole.
