The invention relates to an intervertebral disc prosthesis comprising at least two plates (1, 2), namely first (1) and second (2) plates, articulated about each other by means of a curved surface (11, 31), namely articulation, of at least one of the plates, each of the plates (1, 2) comprising a surface (14, 24) known as a contact surface, intended to be in contact with a vertebral plate of one of the vertebrae between which the prosthesis is intended to be inserted, this contact surface for each of the plates comprising a geometrical centre (G1, G2) at equal distance from at least two diametrically opposite points located on the periphery of the plate (1, 2), characterised in that the geometric centres (G1, G2) of the plates (1, 2) are not vertically aligned, this off-setting (D) of the geometrical centres (G1, G2) of the plates engendering an off-setting of the edges of the plates (1, 2) in at least one direction perpendicular to the vertical axis of the spinal column.
Embodiments of instrumentation and methods are provided for the insertion of intervertebral disc prosthesis. The instrumentation of the embodiments comprises a guide comprising at least two lateral faces, at least one upper plate, at least one lower plate, at least one retainer, a cage defining an insertion axis for the prosthesis, and an angle adjuster adapted to adjust an angle formed by the insertion axis and an antero-posterior sagittal axis; and at least one separator sized to maintain a gap between the upper vertebra and the lower vertebra. Methods for implanting a prosthesis using the disclosed instrumentation comprise implanting a pin in the median sagittal axis of a vertebrae; measuring the dimensions of the intervertebral space; choosing the prosthesis; choosing the guide; adjusting the angle adjuster; positioning the guide adjacent to the intervertebral space; inserting the prosthesis into the guide; and inserting the prosthesis into the intervertebral space.

INSTRUMENTATION AND METHODS FOR INSERTING AN INTERVERTEBRAL DISC PROSTHESIS
Embodiments of instrumentation and methods are provided for the insertion of intervertebral disc prosthesis. The instrumentation comprises a guide (1) comprising at least two lateral faces, at least one upper plate (17) , at least one lower plate (18) , at least one retainer (100) , a cage defining an insertion axis for the prosthesis, and an angle adjuster (12) adapted to adjust an angle formed by the insertion axis (x) and an antero-posterior sagittal axis (s) ; and at least one separator (10) sized to maintain a gap between the upper vertebra and the lower vertebra. Methods for implanting a prosthesis using the disclosed instrumentation comprise implanting a pin (2) in the median sagittal axis of a vertebrae; measuring the dimensions of the intervertebral space; choosing the prosthesis; choosing the guide; adjusting the angle adjuster; positioning the guide inserting the prosthesis into the guide and into the intervertebral space .
The present invention relates to an intervertebral disc prosthesis comprising at least three pieces including an upper plate, a lower plate, and a movable core at least in relation to a plate, wherein it also comprises two anatomic adaptation elements of which each has, on one hand, a surface in contact with a surface of a vertebra and, on the other hand, a face of which at least a part has a surface in contact with at least a part of the plate opposite to which the anatomic adaptation element is mounted, the anatomic adaptation elements being fixed onto the plates via fixation means.
The disclosure relates to intervertebral disc prostheses, which may comprise at least three pieces including an upper plate, a lower plate, and a core mobile at least relative to the lower plate, the upper surface of the core being in contact with at least a part of the lower surface of the upper plate. Various embodiments have limit stops allowing friction to be limited, while limiting or preventing the movements of the core relative to the lower plate, in translation and in rotation, respectively, along an axis substantially parallel to the lower plate and about an axis substantially perpendicular to the lower plate, and have at least one hole disposed along the lower surface of the core facilitating sliding of the core relative to the upper surface of the lower plate with which it is in contact. Instruments for inserting intervertebral prostheses are also disclosed.
