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.

This invention relates to an orthopaedic joint prosthesis implant kit (). The implant kit comprises a stem component () of an orthopaedic joint prosthesis which is intended for articulation with a mating component of the joint. The stem component has a distal end () and a proximal end (), and a neck part () at the proximal end, and is configured for fixation in a bone cavity-using bone cement material with the distal end within the cavity and the proximal end at the opening of the cavity, and with the neck part protruding from the cavity towards the mating component of the joint. The implant kit further comprises a positioning kit (), at least one spacer () for location between the wall of the cavity and the stem component at its proximal end, and a delivery device ().
