The invention concerns a stabilized interbody fusion system for vertebrae, of the type comprising an interbody implant (4) designed to be inserted in the intervertebral space defined between two neighboring vertebrae to be mutually secured, so as to restore the height and the angle of the lordosis of the vertebral segment defined by the two neighboring vertebrae and a stabilizing plate (17) provided, at each of its ends, with at least a passage hole (18) for an anchoring screw, the plate (17) and the implant (4) being provided with mutual assembly means, such that after assembly, the stabilizing plate (17) extends on each side of the implant to enable the stabilizing plate to be anchored on the neighboring vertebrae through the screws, characterized in that it comprises spacing means (30), interposed between the stabilizing plate (17) and the implant (4), to enable the stabilizing plate to be positioned at a specific distance relative to the implant.
