摘要： This prosthesis (1) comprises: -two pairs (2, 3) of elongated joint elements (6-9) forming disc joint surfaces (6e- 9e) and facet joint surfaces (6b-9b); -means (10a, 10b, 11a, 11b) for positioning one pair (2, 3) of elements relative to the other. According to the invention, -each disc joint surface (6e-9e) is in the shape of a hemisphere portion; -said positioning means comprise posterior positioning surfaces (10a-11b); -the prosthesis is associated with at least one rigid transverse element (4, 5) comprising positioning surfaces designed to be placed against said posterior positioning surfaces (10a-11b), this placement making it possible to perform relative positioning of one pair of joint elements (6, 8) relative to the other pair of joint elements (7, 9) such that the disc joint surfaces (6e, 7e, 8e, 9e) are situated in a same geometric hemisphere (H).

摘要： This prosthesis (1) includes two plates (2, 3) and an intermediate damping core(4) placed between both of these plates (2, 3), this core (4) comprising a first shell (6) and a flexible element (11) placed between this first shell (6) and a part (5; 2) for receiving this core, said first shell (6) and said first receiving part (5; 2) comprising means (18, 26) for guiding their mutual movement for bringing them closer or moving them away from each other. According to the invention, -said receiving part (5; 2) comprises a cavity (19) intended to snugly receive the flexible element (11), this cavity (19) being delimited by a first peripheral wall (18) and by a bottom wall, said first peripheral wall (18) having an external peripheral face; and -said first shell (6) has a second peripheral wall (26) forming an internal face, this internal face, when said first shell (6) and the receiving part (5; 2) are in their assembling condition, coming into close proximity to said external peripheral face and being able to slide along the latter.
