An intervertebral implant (1), having an upper section (10) provided with
a ventral side area (11), a dorsal side area (12), two lateral side areas
(13,14), a top apposition surface (15) and a bottom surface (16); and a
lower section (20) provided with a ventral side area (21), a dorsal side
area (22), two lateral side areas (23,24), a bottom apposition surface
(25) and a top surface (26). The two sections (10;20) are moveable in
relation to each other by means of two joints (38;39) arranged between
the two sections (10;20), the two joints (38;39) are realised by an upper
joint section (31) connected to the upper section (10), a central joint
section (32) and a joint section (33) connected with the lower section
(20). One of the external joint sections (31;33) comprises at least one
concave sliding surface (58) rotation-symmetrical with regard to a swivel
axle (3;4); and the other of the external joint sections (31;33)
comprises at least one convex sliding surface (55) rotation-symmetrical
with regard to the other swivel axle (3;4).
