Abstract: A bone stabilization implant includes a stabilization plate provided with anchor orifices intended to receive bone anchor screws and a locking element secured in rotation to a pivot shaft pivotally mounted in a bore of the plate and movable between a rest position and a locking position of the bone anchor screw. The locking element is integrally disposed inside a recess and its lower face has a central area bearing on a bottom wall of the recess and at least one peripheral area adapted to at least partially cover an anchor orifice in the locking position. The lower face has a convex shape according a radial axis extending radially to its peripheral area.

Abstract: An intersomatic prosthesis with lateral introduction with a prosthesis body symmetrical along a sagittal plane is provided. The intersomatic prosthesis includes a convex anterior lateral wall along an anterior radius of curvature and a convex posterior lateral wall along a posterior radius of curvature larger than the anterior radius of curvature, a right end wall and a left end wall, and a lower bearing wall and an upper bearing wall open onto an inner space. The lower bearing wall has a central lower portion provided with lower teeth having lower bearing tips defining a lower bearing surface which is planar, and the upper bearing wall has a central upper portion provided with upper teeth having upper bearing tips defining an upper bearing surface which is convex.

Abstract: A bone implant including a plate with an orifice extending along a steering axis capable of receiving an anchor screw extending along a screw axis, where a first blocking member is arranged in a first peripheral housing formed in the orifice, and a second blocking member is arranged in a second peripheral housing formed in the orifice and offset relative to the first housing according to the steering axis, and the orifice includes a lower portion providing a bearing with polyaxiality to the anchor screw so that the screw axis can form with the steering axis a screw angle with an adjustable measurement, and the blocking members are elastically deformable between an open configuration, in which they authorize an insertion of the anchor screw, and a closed configuration, in which they prevent an extraction of the anchor screw regardless of the measurement of the screw angle.

Abstract: An intervertebral prosthesis for insertion by posterior approach, designed to be inserted in pairs between two vertebral bodies, said prosthesis consisting of a prosthesis body extending in a longitudinal direction of intervertebral insertion, including peripheral faces delimiting, on the inside, an inner space for receiving a bone substitute. The prosthesis includes a prosthesis body of which the lower and upper bearing faces have a convex profile having continuously variable convexity in the longitudinal direction. The invention is intended for the treatment of individuals suffering from disc degeneration in the thoracic or lumbar vertebrae.
