This Implant (1) includes, in a known manner, two pieces (2, 3) that are telescopically mobile relative to one another and elements (4) for positioning one piece (3) in a particular position relative to the other piece (2), the two pieces (2, 3) being made from a polymer material. At least one of the two pieces (2, 3) has a plurality of micro-cavities (15, 20, 32) over at least one wide portion of its peripheral wall (5); and the implant includes internal communications (16, 21, 33) in its wall(s) (5, 7, 31) including the micro-cavities (15, 20, 32), connecting all or some of the micro-cavities to one another.
