Intervertebral implant

An intervertebrae implant comprising:

• two spaced side walls,
• a front wall connecting the side walls at one end thereof,
• a back wall connecting the side walls at their other end,
• the walls defining a corresponding space within the walls,
• a bottom face,
• a top face,
• each face extending transversely to said walls,
• at least one member disposed within the space defined by said walls, said member having a surface oriented toward one of the bottom face or the top face,
• an adjusting element, which is supported in the front wall and the back wall, and which cooperates with the member such that the member is reciprocally movable between a first end position wherein the surface does not project beyond the bottom face or the top face and a second end position wherein the surface at least partially projects outwardly beyond the bottom face or the top face;
• and
• a stop that limits the outward movement of the member;
• wherein the stop comprises a pin supported in the side walls and extending substantially parallel to the front wall and the back wall;
• wherein said member further comprises a U-shaped slit extending transversely to said surface, said slit cooperating with said pin to limit the outward movement of the member.
