The intervertebral implant comprises a frame-type cage (1) which is open at its top and base faces (11 and 12 respectively) with two lateral faces (13, 14), a front wall (15) and a rear wall (16). A rotating element (2) is mounted in the cage (1) so as to be capable of rotation. The outer surface of the rotating element (2) is provided with a helical structure (21). The helical structure (21) protrudes beyond the cover and the base faces (11, 12) outside the confines of the cage (1). The front wall (15) has an aperture (17) for the introduction of a drive tool with which the rotating element (2) in the cage (1) can be made to rotate.
