Abstract
An acetabular prosthesis for implantation in an acetabulum and surrounding pelvis is described. The acetabular prosthesis includes an acetabular cup having a substantially concave inner surface and a substantially convex outer surface, wherein an area defining a groove is located on the outer surface of the acetabular cup. An optional spacer member, having a raised ridge formed on a surface thereof, slidably engages the groove. The spacer provides augmentation and load bearing support in cases where bone tissue loss has occurred in and around the acetabulum. A fastener, such as a surgical screw, is used to secure the acetabular cup, and the optional spacer, to the acetabulum. At least one attachment member is integrally formed with the acetabular cup for fastening to a surface of the pelvis, such as the ilium and/or the ischium. Another optional spacer member is provided for the attachment member to provide augmentation around the attachment points on the pelvis. A fastener, such as a surgical screw, is used to secure the attachment member, and the other optional spacer, to the pelvis. The described acetabular prosthesis is especially useful in revision hip implant procedures where significant bone tissue loss has occurred either in or around the acetabulum and/or the pelvis.
