The present invention relates to a vertebral system comprising a vertebral implant () and a plurality of inserts, said implant being designed to be implanted in a vertebral segment composed of at least two vertebrae and including a body () the walls whereof delimit a cavity () leading to the outside of the body () through at least one opening in at least one of said walls, at least one passage () passing through the implant () from the periphery to an upper or lower surface to receive a bone-anchoring device () capable of anchoring the implant () in at least one of said vertebrae, the system being characterized in that it includes at least two inserts selected from among the following inserts:

Vertebral system, implant and inserts for vertebral system

The present invention relates to an implant, an instrument for implanting the implant, and a method for manufacturing the implant which includes an elongated body between a free end and a head along a longitudinal axis on the one hand and turns of at least one threading on at least one portion of said body in proximity to the free end, along the longitudinal axis on the other hand, characterized in that the body includes a longitudinal internal conduit in at least one portion to along the longitudinal axis, obtained by at least one first central machining operation parallel to the longitudinal axis and at least one second machining operation in a so-called transverse plane, not parallel to the longitudinal axis and crossing the wall of the body as far as the longitudinal internal conduit by making windows communicating between said longitudinal internal conduit and the outside of the body.
