Claim Text:
1. An acetabular prosthetic device for implantation in an iliac canal and acetabulum of an ilium, comprising: a stem configured to be implanted in the iliac canal; and an acetabular component comprising an acetabular outer shell configured to be implanted in the acetabulum and fixed to the stem, the acetabular outer shell including an external outer bone bearing surface, and further comprising a connection portion to adjustably connect the acetabular outer shell to the stem such that the acetabular outer shell is configured to be oriented in a plurality of orientations before being fixed to the stem, wherein the connection portion comprises at least one augment having a first curved surface geometry that substantially conforms to and is matingly engaged with a second curved surface geometry defined by the external outer bone bearing surface of the acetabular outer shell to selectively orient and position the acetabular outer shell relative to the stem, wherein the stem is rigidly engaged in abutment against an external surface of the at least on augment opposite the first curved surface geometry, wherein the first curved surface geometry of the at least on augment is rigidly engaged in abutment against the external outer bone bearing surface of the acetabular outer shell to fix the acetabular outer shell at a select orientation and position relative to the stem, and wherein the external outer bone bearing surface of the acetabular outer shell comprises a porous surface configured to promote bone ingrowth into acetabular outer shell.
