<p>The invention concerns an implant (2) comprising, over part of its periphery, two rigid linings (16) designed to be in contact with two neighbouring vertebrae respectively, the vertical dimension of the set implant increasing towards the front part thereof and varying between a minimum dimension and a maximum dimension. Said implant further comprises a removable core (4), provided with two upper and lower peripheral contact zones (6) with each lining, the vertical distance separating the two peripheral zones (6) increasing towards the front part of the implant, and the two linings (16) are shells capable of adopting an intermediate configuration wherein the vertical spacing between their outer surfaces is substantially constant or decreasing towards the front, said shells (16) forming, in said intermediate configuration, an internal volume adapted to receive said removable core (4).</p> |
