Abstract
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.

An acetabular prosthesis for use in a hip arthroplasty surgical procedure, the acetabular prosthesis comprising:
- a ceramic acetabular shell liner component configured to be secured to an acetabular shell component;
- a metal ring affixed to and encircling the ceramic acetabular shell liner component, wherein the metal ring includes a distal rim and a set of keys and wherein each key of the set of keys extends distally away from the distal rim and curves outwardly from the distal rim;
- and
- an augment molded over the set of keys and distally extending from the metal ring, wherein 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.
