The present invention relates to an internal fixator device (1) of the bone plate type to be used as synthesis means in anatomical regions or epiphyses/ metaphyses with poor coating of soft tissue, of the type comprising a two-lobe or eight-shaped bone plate (2) comprising a pair of lobed portions (23, 24) which are linked by a central linking portion (15) and in each of which at least one through-hole (3, 4) is formed to receive a corresponding bone fixation screw (5). Advantageously, each of the pair of lobed portions (23, 24) of the bone plate (2) has an upper surface (7) inclined relative to a reference plane (X) coinciding with a second upper surface of the linking central portion (15) of the bone plate (2), and a lower surface (6) configured for contact with the bone and inclined relative to the same reference plane (X) with a smaller inclination.
