THE DEVICE FOR OSTEOSYNTHESIS COMPRISES A BONE PLATE (1) INCLUDING A BOTTOM SURFACE (2) DESIGNED TO BEAR AGAINST THE BONE, A TOP SURFACE (3), AND AT LEAST ONE THROUGH HOLE (4) CONNECTING THE BOTTOM SURFACE (2) WITH THE TOP SURFACE (3) AND DESIGNED TO RECEIVE A MULTIAXIALLY ADJUSTABLE BUSHING (10) FOR A BONE SCREW (20), SAID THROUGH HOLE (4) HAVING A CENTRAL AXIS (5), AS WELL AS A BUSHING (10) INSERTABLE INTO SAID THROUGH HOLE (4), INCLUDING A CENTRAL BORE (11) DESIGNED TO RECEIVE A BONE SCREW (20), SAID BORE (11) HAVING A LONGITUDINAL AXIS (12), AS WELL AS A PERIPHERAL OUTSIDE FACE (17) DESIGNED TO BE IN CONTACT WITH THE THROUGH HOLE (4). @THE BUSHING (10) IS REALISED IN SUCH A WAY AS TO BE RADIALLY COMPRESSIBLE AND RADIALLY EXPANSIBLE AND THE CROSS SECTION (6) OF THE THROUGH HOLE (4) EXTENDING ORTHOGONALLY TO THE CENTRAL AXIS (5) IS OF NON-CIRCULAR SHAPE. @THE CROSS SECTION (16) OF THE BUSHING (10) EXTENDING ORTHOGONALLY TO THE LONGITUDINAL AIXS (12) HAS A FORM CORRESPONDING SUBSTANTIALLY TO THAT OF THE CROSS SECTION (6) OF THE THROUGH HOLE (4) OF THE BONE PLATE (1), AND THE BUSHING (10) WHICH IS PLACED IN THE THROUGH HOLE (4) IS ROTATIONALLY STABLE RELATIVE TO ITS LONGITUDINAL AXIS (12), WHILE REMAINING ADJUSTABLE WITHIN THE THROUGH HOLE (4) AS TO ITS ORIENTATION RELATIVE TO THE BONE PLATE (1). |
