摘要:
The invention relates to the set of bone plate and bone screw used to stabilize periarticular and/or shaft fractures of the skeletal system. The set of bone plate (1) and bone screw (7) used to stabilize fractures wherein the angularly positioned locking screw (7) that has a threaded head (8) cooperates with a threaded hole (6) of the bone plate (1) characterized in that the top surface (3) of the plate (1) in the area of holes (6) for bone screws (7) insertion has at least one shaped overpress, preferably spherical or oval-shaped which has a concave (1A) or convex (1B) portion in relation to the top surface (3) of the plate (1) and a concave (2A) or a convex (2B) portion with respect to the bottom surface (4) of the plate (1). In the convex (2B) portion of the overpress, a recess (5) is performed, and the depth (G) of the overpress increases with the angle of inclination ± of the plate (1) hole (6) axis (10) in relation to the axis (11) perpendicular to the top surface (3) of the plate (1).
