Abstract: The invention relates to a cage-type intervertebral implant that is made up of a dished side wall (1), a cambered side wall (2), a front part (3), a rear part (4) and at least one intermediate wall (5, 6), thus comprising at least two cavities (7, 8, 9). An upper and a lower cage surface (10, 11) include a first lordosis angle (&agr;1) in the direction front part—rear part and a second lordosis angle (&agr;2) perpendicular thereto, said cage surfaces (10′, 11) intersecting outside the cage. The cage structure is characterized by a double-wedge geometry (double-wedge-shaped cage) that is defined by the two lordosis angles (&agr;1) and (&agr;2) and that advantageously adapts itself to the anatomical conditions in the intervertebral area. The cage is further characterized by a high moment of tilt that effectively counteracts a tipping of the cage.
