Abstract:
A cage for a cage-like intervetebral implant, comprising a member divided into cavities, wherein the cage comprises a dished inner side wall, a cambered outer side wall, a front part, and a rear part, a first, inner readius of curvature being allocated to the dished inner wall, and a second, outer radius of curvature being allocated to the cambered outer side wall; the side walls are connected to the front part and the rear part; the side walls are connected to at least one intermediate wall substantially perpendicular to the side walls, whereby the cage has at least two cavities; and the side walls, the front part, the rear part, and at least one intermediate wall form an upper and a lower cage surface, a first lordosis angle being formed between said upper and lower cage surfaces in a front partâ€”rear part direction such that said upper and lower cage surfaces are not parallel to each other in said front partâ€”rear part direction, and second lordosis angle being formed between said upper and lower cage surfaces in an outer side wallâ€”inner side wall direction perpendicular to said front partâ€”rear part direction such that said upper and lower cage surfaces are not parallel to each other in said outer side wallâ€”inner side wall direction.
