Abstract
An osteosynthesis device comprises a plate and screws which are screwed into bone through holes in the plate. The diameters of the holes at the top face of the plate are larger than at the bottom face of the plate. The screws have a spherical head which, when screwed in rests snugly against the wall of the screw hole with an annular contact surface. Both when the screw is located perpendicularly with respect to the plate and when located at an angle with respect to the plate, the contact surface is located above the center line of the hole depth.
