    摘要： This disclosure relates to intervertebral disc prostheses which may have an upper plate, a lower plate, and a mobile core, with the upper surface of the core being in contact with at least a part of the lower surface of the upper plate. In some configurations, limit stops reduce friction 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. Instrumentation for insertion of the prostheses into intervertebral spaces is also described.

    摘要： An expansible intervertebral implant is disclosed, various embodiments of which comprise an elongated body along a longitudinal axis comprised between a proximal end and a distal end, a flexible arm mounted in the vicinity of the distal end of the longitudinal body and movable between: a folded-back position with the arm substantially parallel to the axis, and a deployed position with the arm not parallel to the axis and away from the body to expand said implant along an axis, by assuming the general shape of a circular arc, a means for deployment of said flexible arm for deploying the latter from the folded-back position to the deployed position, by the sliding of a proximal portion of said flexible arm with respect to the body inducing an increase in the space occupied by the implant, greater than the space of the implant in the folded-back position.

    摘要： Various embodiments of an intervertebral implant comprise a body extending longitudinally along a primary axis, a baseplate, a plurality of elongated arms having a vertebral support surface, the arms being articulated such that the implant has a folded-back position in which the arms are close to each other, and a deployed position in which the arms are moved away from each other, and expansion means between the folded-back and deployed positions, comprising at least two branches pivotably mounted relative to each other and attached to the elongated arms by guide means such that translation of the expansion means parallel to the primary axis causes pivoting of the branches and moves the arms away from each other.
