Prostheses, acetabular apparatuses, and methods of use are disclosed. In some embodiments, an acetabular apparatus includes an acetabular cup and an acetabular cage disposed within an interior of the acetabular cup. The acetabular cage may include a central portion including a first section and a second section rotatably coupled together, and a first flange extending from the first section and a second flange extending from the second section. The acetabular prosthesis may further include a fastener extending through each of the acetabular cup and the central portion of the acetabular cage.

An acetabular orthopaedic prosthesis and method are disclosed. The acetabular orthopaedic prosthesis includes a shell configured to engage a surgically-prepared surface of a patient's acetabulum. The shell includes one or more mounting holes that extend through the inner surface and the outer surface. A plurality of plugs are configured to be coupled to the shell, and each plug is sized to be positioned in at least one of the mounting holes of the shell. A bone screw is configured to be inserted through one of the plurality of plugs into the surgically-prepared surface to secure the shell to the patient's acetabulum.

An implantable compensating sleeve is for application between a longitudinal implant section of a first implant, and a second implant that encompasses the longitudinal implant section of said first implant. The compensating sleeve has a sheath with a sheath body and a passage, running from the proximal to the distal end of the sheath body, for receiving said longitudinal implant section of the first implant. The sheath body is formed from separate planar and/or rod-shaped compensating elements which are arranged in a ring and aligned in the longitudinal direction of the sheath body. A gap runs from the proximal to the distal end between two adjacent compensating elements. Adjacent compensating elements are interconnected by at least one foldable wire such that they can move relative to one another.
