摘要： The invention relates to an intervertebral implant (1) characterised by the following: both parts (10; 20) can be displaced in relation to one another by means of two joints (38;39) that are located between the two parts (10; 20); each of the joints (38; 39) has a rotational axis (3; 4) and the two rotational axes (3; 4) run transversally to one another; the two joints (38; 39) are configured by an upper joint section (31) that is connected to the upper part (10), a central joint section (32) and a lower joint section (33) that is connected to the lower part (20); one of the outer joint sections (31; 33) comprises at least one concave sliding surface (58) that is rotationally symmetrical in relation to the rotational axis (3; 4); and the central joint part (32) comprises a convex sliding surface (57) that complements said concave sliding surface (58). The remaining outer joint part (31;33) comprises at least one convex sliding surface (55) that is rotationally symmetrical in relation to the other rotational axis (3; 4) and the central joint part (32) comprises at least one concave sliding surface (56) that complements said convex sliding surface (55).

摘要： An intervertebral implant (1), especially an artificial intervertebral disc, comprising a central axis (2), an upper part (10) which can be arranged on the base plate of a vertebral body located thereabove, and a lower part (20) which can be arranged on the cover plate of a vertebral body located therebelow. A) The upper part (10) comprises a ventral side surface (11), a dorsal side surface (12), two lateral side surfaces (13,14), an upper apposition surface (15) and a lower surface (16).B) The lower part (20) comprises a ventral side surface (21), a dorsal side surface (22), two lateral side surfaces (23, 24), a lower apposition surface (25) and an upper surface (26). C) The two parts (10, 20) can be moved in relation to each other by means of two joints (38; 39) disposed between the two parts (10; 20). D) Each of the joints has an axis of rotation (3; 4) and the two axes of rotation (3; 4) are arranged crosswise in relation to each other. E) The two joints (38; 39) are formed by an upper, a central and a lower joint part (31; 32; 33). The invention is characterised in that F) each joint (38; 39) comprises a first joint part (31; 32; 33) provided with an elevation (49; 59) comprising an edge (51; 53) for the tiltable positioning of a second joint part (31; 32; 33) around the axis of rotation (3; 4).

摘要： The invention relates to an intervertebral implant (1), in particular an artificial intervertebral disc. Said implant comprises a central axis (2), an upper part (10), designed to rest against the lower surface of a vertebral body lying directly above and a lower part (20), designed to rest against the covering surface of a vertebral body lying directly below. According to the invention: the upper part (10) comprises a ventral side face (11), a dorsal side face (12), two lateral side faces (13, 14), an upper apposition face (15) and a lower face (16); the lower part (20) comprises a ventral side face (21), a dorsal side face (22), two lateral side faces (23, 24), a lower apposition face (25) and an upper face (26); and the two parts (10, 20) can be displaced in relation to one another by means of a joint (30) that is situated between the two parts (10; 20), said joint (30) being a universal joint comprising two rotational axes (3; 4) running transversally to one another.
