Claim:
An orthopedic prosthesis for implantation into a bone of a patient, said orthopedic prosthesis comprising: a shell adapted to be affixed within the bone, said shell having an outer bone engaging surface, an inner surface, and an elongated continuously open slot that extends along a radial axis of said shell between a first terminal end positioned near an apex of said shell and a second terminal end positioned between said apex and an upper rim of said shell, said continuously open slot extending through said outer and inner surfaces; an augment having a body that includes a shell facing surface having a plurality of protrusions integrally formed thereon, said plurality of protrusions collectively defining an outer boundary configured to engage the outer surface of the shell thereby offsetting the shell facing surface of the augment from the outer surface of the shell, said body defining a passage through said augment at a location inward of said outer boundary; and a securing member extending through said passage and said continuously open slot, wherein said securing member is movable between a locked position wherein said augment is precluded from relative movement with said shell and an unlocked position wherein said securing member is adapted to move between a first fixed position on said continuously open slot and a second fixed position on said continuously open slot to locate said augment at said first and second fixed positions against said outer bone engaging surface and along said radial axis, wherein said shell facing surface is offset from said outer bone engaging surface in said locked position by said plurality of protrusions.
