Implant for the fixation of a first and second bones (12, 14) at a first site, the implant comprising: a body (38) having a central axis (40) and a depth dimension (D) between a first and second axially separated ends (42, 44), the body (38) having an outer surface (48) coinciding at least nominally with a tapered surface (34) around a receptacle (30) formed at the first site by rotating an element of cutting (32) around a second axis, the outer surface (48) and the tapered surface (34) of the body (38) being configured so that as the body (38) is advanced along the central axis (40) to an operative position within the receptacle (30), the outer surface (48) and the tapered surface (48) of the body (38) cooperate to make the central and second axes substantially consistently align, a plurality of openings (70, 72) in the body (38), to accept each a threaded fixing element (66, 68), comprising the plurality of openings (70, 72): a) a first opening (72) through which a first threaded fixing element (68) can be directed to along a first line through the body (38) functionally positioned and inside one of the first and second bones (12, 14)； and b) a second opening (70) through which a second threaded fastener (66) can be directed along a second line through the functionally positioned body (38) and into one of the first and second bones (12, 14), in which the first opening (72) is formed so that the first threaded fastener (68) can be advanced into one of the first and second bones (12, 14) in a line substantially parallel to the central axis (40) of the body (38) by threading the first threaded fastener (68) inside the bone (12, 14), and further comprising the first threaded fastener (68) adapted to be received at the first opening (72).Implante para la fijación de un primer y segundo huesos (12, 14) en un primer sitio, comprendiendo el implante: un cuerpo (38) que presenta un eje central (40) y una dimensión de profundidad (D) entre un primer y segundo extremos axial
