Abstract

A bone plate (1) with at least one receiving opening (2) for a bone screw (3) with a screw head (4), wherein the receiving opening (2) has a compression area (5) with a compression contour (6) and a blocking area (7) with a blocking contour (8). The compression contour is designed such that rotation of the bone screw in its one screwing-in direction (E) causes lateral movement of the bone screw toward the blocking area (7). The compression contour (6) is designed as an engagement contour (6), such that lateral movement is generated by engagement between the engagement contour (6) and a mating contour (9) on the screw head or tool. A surgical kit containing at least one such bone plate (1) and at least one bone screw with a screw head (4), which bone screw is insertable into the receiving openings of the bone plate (1) is also disclosed.
