Patent ID: 8535386

Claim:
A prosthetic implant comprising: a prosthetic femoral stem having first and second portions spaced along a longitudinal axis and respectively having first and second diameters, the first diameter larger than the second diameter, a modular augment having a first end, a second end, a constant diameter region, and an inwardly tapered region, said augment defined by: a non-porous solid body having a central axis, an inner surface and an outer surface, the inner surface extends circumferentially about the central axis and receives the stem first portion; a porous structure having an inner surface integrally formed on at least a portion of the non-porous body outer surface and having a tissue contacting outer surface; and a plurality of non-porous solid posts integrally formed on the outer surface of the non-porous body as part of the non-porous body thereby forming a single structure; each of the non-porous posts having a cylindrical side surface and a flat outwardly facing surface, at least two posts are oriented perpendicular to the body central axis and at least two posts are oriented non-perpendicular to the central axis, the posts cylindrical side surfaces are completely surrounded by the porous structure, the posts flat outwardly facing surfaces are not covered by the porous structure tissue contacting outer surface, the axis of at least two non-porous posts lying in a single plane perpendicular to the body central axis, wherein there is at least two non-porous posts within the constant diameter region and at least two non-porous posts in the tapered region.
