The invention relates to an osteosynthesis plate (1) for reducing a distal fracture (2) of an elongate bone (3). The plate comprises a widened, pallet-shaped epiphyseal portion (4), provided with first attachment holes (6) for first anchoring screws (7), and an elongate diaphyseal portion (8), provided with second attachment holes (9) for second anchoring screws (10). The plate comprises a hinge, between the epiphyseal portion and the diaphyseal portion, within the plane of said diaphyseal portion between two angle values that are predetermined relative to a central alignment position (18).
