Osteosynthesis plate and method for producing an osteosynthesis plate

An osteosynthesis plate (P) for fixing bone fragments, the osteosynthesis plate (P) comprising:

• an elongate main body (G) with a top side (G1) and an underside (G2), the underside (G2) arranged opposite the top side (G1) on the elongate main body (G), the underside (G2) configured for placement on the bone fragments, the osteosynthesis plate (P) defining a plurality of openings (A) for accommodating one screw (SK) each;
• and
• an annular insert (R) formed as one piece is arranged in at least one of the openings (A), the insert (R) comprising a first portion (R1) and a second portion (R2), wherein the first portion (R1) faces the top side (G1) of the elongate main body (G) and is arranged directly adjacent the second portion (R2) in an axial direction,
• wherein the first portion (R1) has a non-rotationally symmetrical outer contour (AD1), and the second portion (R2) has a rotationally symmetrical outer contour (AD2).
