Abstract: The invention relates to an intervertebral implant including a wedge which is inserted between two spinous processes and has two opposite grooves in which said spinous processes engage, which grooves have substantially parallel axes, and each of which grooves is defined by two flanges. The wedge has at least one central opening between said two grooves and said central opening passes completely through said wedge along an axis Ac substantially parallel to the axes Ag1 and Ag2 of said grooves, which renders said wedge elastically deformable.

Abstract: The invention provides an intervertebral disk prosthesis. The prosthesis comprises: a first fixing element having both an anchoring first face for anchoring in one of the vertebrae and a co-operation second face; a second fixing element having both an anchoring first face for anchoring in the other vertebrae and a co-operation second face; a first prosthesis element having both an active first face and a co-operation second face, said co-operation faces of the first fixing element and of the first prosthesis element serving to fasten the two elements together; a second prosthesis element having both an active first face and a co-operation second face, said co-operation faces of the second fixing element and of the second prosthesis element serving to fasten the two elements together; and each of said active faces of the prosthesis elements defining at least a portion of a spherical cap that is respectively concave or convex.

Abstract: The invention relates to an intervertebral implant comprising a spacer (2) in which two opposite notches (6a, 6b) are formed suitable for receiving two respective spinus processes (26a, 26b) of two vertebrae, each notch defining two flanges (8a, 10a, 8b, 10b) each having an inside wall, and the implant also having a tie (4a, 4b) for holding said spacer on said spinus processes. Said tie is constituted by at least one strap having a portion surrounding a portion of the surface of a spinus process that is opposite from the bottom of the notch. Said implant has first fixing means (12a, 12b) formed in at least one flange (8a, 8b) for fixing a first end (18a, 18b) of said strap, and self-locking second fixing means (14a, 16a, 14b, 16b) formed in at least one other flange (10a, 10b) and through which the second end (20a, 20b) of said strap is inserted and then pulled to hold said strap (4a, 4b) in position, thereby securing said spacer (2) to said spinus processes (26a, 26b).

Abstract: The invention provides an intersomatic implant suitable for containing at least one bone graft and for being inserted in the intervertebral space along a predetermined direction. It comprises: a first portion (10) of generally annular shape surrounding an aperture (11) and presenting a top first edge (12) and a bottom first edge (14); and a second portion (16) of elongate shape along its main axis (A) presenting a bottom second edge (18) and a top second edge (20), and interconnecting two facing opposite regions of said first portion (10) along said predetermined direction, thereby dividing said aperture (11) into two housings suitable for containing said bone graft, at least one of said bottom and top second edges projecting from the space defined by said bottom and top first edges (14, 12) of the first portion (10).
