摘要:
The invention provides an intervertebral implant for the lumbo-sacral joint, the implant comprising a spacer suitable for being disposed between the fifth lumbar vertebra L5 and the vertebra S1 of the sacrum that is articulated to the vertebra L5. The implant comprises a flexible tie having end portions suitable for being fastened to the sacrum with the help of fasteners such as pedicular screws. The flexible tie has an intermediate portion suitable for co-operating with a connection system such as a hook provided on the spacer so that the flexible tie connects the spacer to the sacrum. The flexible tie is put under tension in such a manner as to exert a return force on the spacer towards the vertebra S1.

A disc prosthesis for vertebrae is provided. The disc prosthesis comprises a first plate, a first insert, a second plate, and a second insert. The first plate comprises a first active face and a first anchor face. The second plate comprises a second active face and a second anchor face. The first anchor face is configured to anchor the first plate to a first vertebra. The second anchor face is configured to anchor the second plate to a second vertebra. The first plate comprises a cavity for receiving the first insert. The cavity comprises a concave spherical cap. The second plate comprises an opening that connects the second active face to the second anchor face. The second insert comprises a fastener portion, said fastener portion is friction fit in the opening.
摘要:
A device for attaching a flat and flexible band on at least one bone part, comprising the band having two end portions, a rigid base body crossed by an opening, and a retaining part that can be inserted in the opening. The retaining part is at least partially in the shape of a squeezable wedge comprising a central bore for passage of the end portions facing the flexible band, the bore having a transverse cross-section that can be deformed between a first cross-section for free passage of the end portions when the part has not been inserted in the opening and a second cross-section for locking the end portions by compression when the part is entirely or substantially entirely inserted in the opening.
摘要:
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.
摘要:
The invention relates to a distractible intervertebral implant having a first assembly (10) constituted by a first prosthetic plate (16) and a first spacer element (18), the prosthetic plate being secured to the first spacer element; a second assembly (12) constituted by a second prosthetic plate (22) and by a hollow second spacer element (24), having a first end secured to the second prosthetic plate and the first spacer element being suitable for sliding in the second spacer element; and means (14) for preventing the spacer element from moving in translation or in rotation relative to each other, the means having a clamping collar (28) surrounding a portion of the outside surface of the second spacer element, and a lock screw (30) for tightening the collar onto the second spacer element.
摘要:
The invention concerns a backbone osteosynthesis system, in particular for anterior fixing comprising: an elongated linking element; a vertebral screw with a threaded head; a connector comprising two branches capable of being engaged onto the screw and clamping between them the linking element; and a threaded clamping member capable of co-operating with the head for clamping the branches. The head has a threaded orifice, the clamping member comprising a threaded rod capable of being urged to be engaged in the orifice.
