Ceramic acetabular shell liner with a metal ring having a lead-in surface
An acetabular prosthesis for use in a hip arthroplasty surgical procedure is disclosed. The acetabular prosthesis includes an acetabular liner assembly to be secured to an acetabular shell component. The acetabular liner assembly includes a ceramic acetabular shell liner component. The acetabular liner assembly also includes a metal ring affixed to and encircling the ceramic acetabular shell liner component. The metal ring includes a proximal rim shaped to define a lead-in surface.
IMPLANT COMPONENTS AND METHODS
Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.

CERAMIC ACETABULAR SHELL LINERS WITH AUGMENTS
An acetabular prosthesis for use in a hip arthroplasty surgical procedure is disclosed. The acetabular prosthesis includes a ceramic acetabular shell liner component configured to be secured to an acetabular shell component. The acetabular prosthesis also includes a metal ring affixed to and encircling the ceramic acetabular shell liner component. The acetabular prosthesis also includes an augment molded to and distally extending from the metal ring. The augment is shaped to modify a range of motion of a femoral prosthetic component when the femoral prosthetic component is fitted into the ceramic acetabular shell liner component. Other embodiments are also disclosed.

METAL REINFORCED ACETABULAR SHELL LINER
An acetabular shell liner for use in a hip arthroplasty surgical procedure is disclosed. The acetabular shell liner includes a semi-hemispherical inner bearing layer, which includes a rim and a dome attached to the rim. The semi-hemispherical inner bearing layer includes a polymeric material having a first thickness, at an apex of the dome, and a second thickness, at the rim, that is less than the first thickness. Additionally, the acetabular shell liner includes a semi-hemispherical outer reinforcement layer mated with and encasing the dome of the semi-hemispherical inner bearing layer. The semi-hemispherical outer reinforcement layer includes a metallic material to provide structural support to the semi-hemispherical inner bearing layer.

Method of implanting an acetabular shell and an augment
Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. An implant may include a base member that has at least two projections with a gap between the projections. The gap between the projections allows the implant to fee implanted around another implanted component, such as around a bone screw of an acetabular shell. The implant may include a fixation element, such as a screw or a cement trough, on one or more projections to couple the implant to an implanted acetabular shell. The implant may also include timing marks to facilitate alignment with corresponding marks on another implanted component.
