Bone plate connected to the bone by means of an inclined screw

Abstract

Abstract A plate, especially a blade plate for cuneiform osteotomy, to be connected to a bone by means of a screw extending at an incline within a predetermined angular range, contains a screw hole, which encircles a seat for the screw head, a narrower through hole for the screw shaft towards the inside from the seat (8), and an external milled-out recess. In order to enlarge the admissible angular range and the maximum admissible angle of the screw relative to the perpendicular direction (10), the seat (8) is arranged at an incline corresponding to a mean value of the predetermined angular range, the centre of the seat (80), whose diameter is greater than the thickness of the plate, lying within the plate limit. In addition, the through hole (11) and the milled-out recess (12) are inclined relative to the perpendicular direction (10) at a greater angle than is the seat (8). The cutting edge of the blade plate is formed by a bevel approximately the same on both sides. <IMAGE>
