Zusammenfassung:Osteosynthesis plate (1) comprising a plate body (10) in which there is formed an anchor through-orifice (2) having a first orifice region (3) and the second orifice region (4) which are secant and joined by an intermediate region (5), the first orifice region (3) being of plain cylindrical overall form and coinciding with a first virtual cylinder, the second orifice region (4) having a second upper segment (42) of plain spherical or frustoconical overall shape centred on a second axis (A2) and a second lower segment (41) of threaded cylindrical overall shape and coinciding with a second virtual cylinder intersecting the first virtual cylinder, a helical rib (6) being formed in the second orifice region to define a screw thread having a screw thread external radius smaller than the major radius of the second upper segment, and the intermediate region (5) being formed of two planar intermediate faces (51) facing one another.
