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).

Abstract: The invention relates to a connecting member for maintaining the spacing between at least two anchor members screwed into vertebrae. It comprises two rigid rod-forming parts (12, 14) made of a first material and each having a fixing, first portion (16, 18) adapted to be fixed into an anchor member and a fastening, second portion (20, 22), said rods (12, 14) being aligned with each other and said fastening portions (20, 22) facing each other, and a connecting body (24) made of a second material which is more elastically deformable than said first material and which interconnects said rigid parts (12, 14) by means of the facing fastening portions (20, 22) so that said connecting body (24) is able to deform elastically, whereby the vertebrae, which are held spaced from each other, are movable relative to each other.

Abstract: The invention concerns an intervertebral implant comprising a wedge designed to be pressed between two spinous processes, said wedge having two opposite grooves each defined by two wings, the axes of said two grooves being substantially mutually parallel and said spinous processes being urged to be supported in said two grooves. The wedge (10) comprises at least a central recess (16) between said two grooves (12, 14), said central recess (16) passing right through said wedge (10) along an axis Ac substantially parallel to said axes Ag1 and Ag2 of said grooves, thereby making said wedge (10) is elastically deformable.

Abstract: The invention concerns a linking piece designed to maintain a spacing between at least two anchoring elements screwed into vertebrae. The piece comprises at least: a flexible part (10) divided into two branches (12, 14), the ends of said branches being interconnected in pairs and defining a first neutral plane (Pm), and, two rigid parts (20, 22) forming rods, having a first fixing C portion (20′, 22′) and a second fixing portion (20″, 22″), each said second portion (20″, 22″) of said rigid parts (20, 22) extending respectively in two opposite directions said ends of said branches interconnected in pairs, such that said linking piece, whereof the fixing portions (20′, 22′) are respectively fixed on each of the anchoring elements is designed to bend elastically perpendicularly to said neutral plane (Pm).

Abstract: A backbone osteosynthesis system for anterior fixing comprising first and second arms, each capable of receiving bone screws and a longitudinal plate for rigidly linking the arms, the plate being in one single piece with the first arm. The system comprises a way to adjust the second arm in a longitudinal position on the plate.

Abstract: The invention concerns an intersomatic implant adapted to contain at least a bone graft and to be inserted in the intervertebral space along a predetermined direction. It comprises: a first part (10), generally annular in shape, enclosing a recess (11) and having a first upper edge (12) and a first lower edge (14), and a second part (16) elongated along its main axis (A) having a second lower edge (18) and a second upper edge (20), and which links along said predetermined direction two opposite portions in line with said first parts (10) dividing said recess (11) into two housings adapted to contain said bone graft, at least a portion of said second lower and upper edges projecting outside the space defined by said first lower (14) and upper (12) second edges of said first part (10).

Abstract: The intersomatic spine implant comprises a body, at least one anchoring element movable relative to the body to project from a contact face of the body making contact with a vertebra, and at least one cam slidable relative to the body and suitable for displacing the anchoring element relative to the body by the effect of a ramp engaging the anchoring element. The cam and the anchoring element are arranged so that the cam moves the anchoring element in two opposite displacement directions.
