A system for spinal surgery includes a prosthesis comprising a plurality of bone anchors which engage an intervertebral construct for fusion or motion preservation. The fusion construct comprises a spacer optionally encircled by a jacket. The motion preservation construct may comprise an articulating disc assembly or an elastomeric disc assembly. Any of the constructs may occupy the intervertebral disc space between adjacent vertebrae after removal of an intervertebral disc. The anchors slidingly engage the construct to securely fix the prosthesis to the vertebrae. The anchors and jacket of the fusion construct provide a continuous load path across opposite sides of the prosthesis so as to resist antagonistic motions of the spine.

Intervertebral endoprosthesis discs suitable for surgical implantation between two vertebrae having and methods thereof. The prosthetic disc may have an endoprosthesis body including an anterior region and a posterior region designed to be positioned between a first vertebra and a second vertebra with a first and second movable insert positioned rotatably in anterior cavities and is rotatable to adjust the fasteners.

The disclosure provides an articular gasket prosthesis and an articular prosthesis with the articular gasket prosthesis. The articular gasket prosthesis includes an elastic gasket disposed between a first skeleton and second skeleton forming a joint, the elastic gasket including: an elastic matrix, having a first contact surface facing the first skeleton and a second contact surface facing the second skeleton; and multiple synovial fluid passages, distributed in the elastic matrix and communicating the first contact surface and the second contact surface, the multiple synovial fluid passages being disposed according to a predetermined manner to gradually increase hardness of the elastic matrix from a center to an edge and gradually decrease elasticity of the elastic matrix from the center to the edge.

An acetabular liner having a closed first end, an open second end, and a liner wall having a distal peripheral edge. The acetabular liner wall can include an interior surface, an exterior surface configured to be received within an acetabular shell, a first cutout through the liner wall, a second cutout parallel to the first cutout and through the liner wall, and a third cutout in the interior surface partially through the liner wall, the third cutout extending between the first and second cutouts, and at least one movable tab extending from the peripheral edge inwardly towards an axial center of the liner and having sidewalls defined by one of the sets of cutouts, the tab comprising at least one projection on an exterior surface of the tab configured to removably secure to a portion of an acetabular shell.

A standalone anterior cervical interbody spacer (ACIF) that includes a spacer body and plate rigidly couple via flexible pins.

A system and method facilitating replacement of comminuted bone fractures or portions thereof adjacent bone joints. The system and method employs a prosthesis to replace at least a portion of the comminuted bone fractures. The prosthesis serves in reproducing the articular surface of the portion or portions of the comminuted bone fractures that are replaced. In doing so, the prosthesis serves in restoring joint viability and corresponding articulation thereof.

An acetabular cup assembly for use with liners is described. The acetabular cup assembly includes a cup and a liner. The cup has an outer surface, a generally concave inner surface and a top face. The inner surface includes a cylindrical band having a plurality of inward-facing recessed scallops, a tapered wall adjacent to the band, and an inner spherical surface adjacent the tapered wall. The inner spherical surface has a substantially uniform radius of curvature. A single groove interrupts the spherical surface. The liner has a substantially convex outer surface and includes a rim and a plurality of outward-projecting scallops adjacent the rim. The scallops of the liner are configured to engage the scallops of the cup when the liner is seated in the cup. Related methods of use are also provided.
