Examples of the invention relate to methods, implants, and instruments for compressing first and second bone portions or a bone portion and an implant together.

An acetabular prosthesis is described that includes a shell having an outer surface and an inner surface, the outer surface defining an external shape. There is at least one through bore extending from the outer surface of the shell to the inner surface of the shell. At least one augment is configured to be positioned at least partially within the at least one through bore of the shell such that, in an assembled state, the shell and the at least one augment define a modified external shape.

A device implantable in a human body comprising a first component, or main support component, delimiting a plurality of openings, and a second component disposed on a surface of the main support component.

A joint implant for temporary or permanent use has a femoral component and tibial component. The femoral component has a base and rod extending therefrom and defines a pin. The tibial component has a base and rod extending therefrom and defines a bore in which the pin is seated so that the femoral component is rotatable relative to the tibial component.

Examples of the invention relate to methods, implants, and instruments for compressing first and second bone portions or a bone portion and an implant together.

Devices and methods are disclosed for joint replacement.

An implant for an artificial hip joint and, more specifically, a dual mobility acetabular cup assembly for an artificial hip joint is configured to have improved locking mechanism between a liner and a shell and improved resistance to micromotion and to guide the liner into the shell with proper orientation by providing stable liner-shell fastening structure to the acetabular cup assembly.

A reverse shoulder replacement system including a humeral liner defining a split curvature bearing surface that includes a plurality of curvature regions. The plurality of curvature regions are configured to engage a glenosphere of a glenoid implant individually or in combination to provide an improved fit between the glenosphere and the humeral liner.

A method of securing an orthopedic hip prosthesis to an acetabulum of a living being. The prosthesis can be a shell or a cup, and the surgery can be a total hip arthroplasty such as a revision total hip arthroplasty. In some examples the method can include placing an augment at a bone surface of the acetabulum, applying a layer of fixation material over the bone surface in an amount sufficient to cover the augment, and then implanting the prosthesis over the layer of fixation material to secure the prosthesis to the layer of fixation material. In various aspects of the method, the augment can be an anchor or a spacer.

Described is an acetabular assembly comprising: an acetabular cup component (100) having an outer convex surface (104), an inner concave surface (106) defining a cup cavity, and a plurality of openings (116) that extend between the inner concave surface and the outer convex surface and that are configured to accommodate a fastener for attaching the acetabular cup component to an acetabulum of a patient; an insert bearing liner (200) defined by an inner concave surface (202) and an outer convex surface (206), and configured to be located at least partially within die cup cavity of the acetabular cup component; and a plurality of spacers (300) that are configured to be inserted into the plurality of openings in the acetabular cup component from the inner concave surface.
