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.

A placeholder for vertebrae or vertebral discs includes a tubular body, which along its jacket surface has a plurality of breakthroughs or openings for over-growth with adjacent tissue. The placeholder includes at least a second tubular body provided with a plurality of breakthroughs and openings at least partially inside the first tubular body. The first and second tubular bodies can have different cross-sectional shapes, can be are arranged inside one another by press fit or force fit or can be connected to each other via connecting pins and arranged side by side to one another in the first body.

Implants for the fusion or fixation of two bone segments are described. For example, the implants can be used for the fusion or fixation of the sacroiliac joint. The implants can have a matrix structure, have a rectilinear cross-sectional area, and have a curvature.

Shoulder arthroplasty systems and configurations for components thereof are described. For example, implant systems for a total should arthroplasty (TSA), hemi shoulder arthroplasty, and reverse should arthroplasty (RSA) are described. In addition, exemplary configurations for baseplates, glenoid components, glenosphere components, humeral components, humeral head components, humerosocket components, connectors, and adaptors, are described.

Orthopedic implants constructs include one or two rigid monolithic plates and a core that is integrally formed within an interior space within a rigid monolithic plate. An exemplary construct that includes two plates between which is a core that is interengaged with each plate, the two plates thereby forming a generally disc-like shaped construct with opposing tissue contacting surfaces. The constructs are suitable, for example for spinal interbody fusion and artificial disc applications.

In one embodiment a method of implanting a prosthetic includes implanting a first member including a concave articulation surface portion defined by a first radius of curvature in a first bone, implanting in a second bone a second member including a first convex articulation surface portion defined by a second radius of curvature and a second convex articulation surface defined by a third radius of curvature, wherein the second convex articulation surface is defined by the lemon portion of a spindle torus and each of the second radius of curvature and the third radius of curvature has a length that is different from the length of the first radius of curvature by less than 0.05 millimeters and wherein the origin of the second radius of curvature is not coincident with the origin of the third radius of curvature, and bringing the first member into slidable contact with the second member.

A bone implant system, a bone implant produced using such a bone implant system, and a method for producing such an implant. The bone implant system includes a plurality of different disc elements having different external diameters. The disc elements can be stacked axially above one another in different combinations to form different stack arrangements owing to the different external diameters of the disc elements. The different stack arrangements have different outer contours. The disc elements each have an interlocking portion situated on an upper face and a complementary interlocking portion situated on an axially opposite lower face, by which interlocking portions the disc elements can be interlockingly fixed to one another in the different stack arrangements in the radial direction and/or the circumferential direction.

An implant for insertion between vertebral bodies of the spinal column, with a main body which is formed along a longitudinal axis and at least one end of which an attachment plate with a contact surface for attachment to an adjacent vertebral body is disposed, which plate is mounted on main body pivotably about a pivot axis, arranged substantially perpendicular to the longitudinal axis, and which can be fixed at an angle relative to it or relative to the longitudinal axis. The main body is assigned at least one clamping element. The attachment plate has a clamping surface on a side facing the main body, and the clamping element is movable between a pivot configuration, in which the attachment plate is pivotable, and a clamping configuration, in which the angle and thereby the attachment plate are fixed by an interaction of the clamping element with the clamping surface.
