    摘要: An orthopedic prosthesis for implantation into a bone of a patient can include a shell, an augment and a securing member. The shell can be adapted to be affixed within the bone and have an outer surface adapted to receive bone ingrowth after implantation. The shell can have an inner surface adapted to engage a liner. An elongated slot can extend between the outer and inner surfaces of the shell. The augment can define a body and have a passage therethrough. The securing member can extend through the passage and the slot. The securing member can be movable between a locked position wherein the augment is precluded from relative movement with the shell and an unlocked position wherein the securing member is adapted to slidably traverse along the slot to locate the augment at a plurality of positions relative to the shell.

    摘要: A system for replacing a portion of a shoulder joint can include a tray having an outer surface and an inner surface. The outer surface can be adapted to engage a humeral stem. A bearing can include an outer bearing surface and an inner articulating surface. The outer bearing surface can be positioned adjacent to the tray. A ring can be selectively disposed between the tray and the bearing. The ring can define an annular body having a slit formed therein. The ring can be movable between a locked position wherein the ring retains the bearing relative to the tray and an unlocked position. A removal tool can define a proximal end and a distal end. The distal end can define a ring engaging surface and a bearing engaging surface. The ring engaging surface can be adapted to engage the ring at the slit such that the ring expands radially from the locked position away from engagement with the bearing to the unlocked position. The bearing engaging surface can be adapted to engage the bearing and urge the bearing away from the tray.

    摘要: An orthopedic prosthesis for implantation into a bone of a patient includes a porous metal shell adapted to be affixed within the bone. The porous metal shell includes an outer surface adapted to receive bone ingrowth and an inner surface adapted to engage a liner. The porous metal shell is porous from the outer surface to the inner surface. A non-porous member may be affixed to the porous metal shell. The non-porous member may include a piercing member extending from the outer surface, the piercing member adapted to penetrate the bone in an implanted position. The non-porous member may include spikes or fins. In one example, the piercing member may define a reduced material cross section at an interface with the outer surface of the porous metal shell. The piercing member may be adapted to be broken at the reduced material cross section and removed from the porous metal shell.
