The present invention relates to an implant, to an instrument for implantation of the latter and to a method for manufacturing this 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 ().

The present invention relates to an implant, to an instrument for implantation of the latter and to a method for manufacturing this 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 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 ().

The present disclosure provides various embodiments that may comprise an implant, to an instrument for implantation of the latter and to a method for manufacturing this 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 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 while preserving at least one portion of said turns and the wall of the body behind the turns, and preserving non-machined portions on the perimeter of said body.
