    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.

    摘要翻译： 用于替换肩关节的一部分的系统可以包括具有外表面和内表面的托盘。 外表面可适于接合肱骨柄。 轴承可以包括外轴承表面和内铰接表面。 外轴承表面可以定位成与托盘相邻。 环可以选择性地布置在托盘和轴承之间。 环可以限定形成有狭缝的环形体。 环可以在锁定位置之间移动，其中环相对于托盘保持轴承和解锁位置。 移除工具可以限定近端和远端。 远端可以限定环接合表面和轴承接合表面。 环接合表面可以适于在狭缝处接合环，使得环从锁定位置径向扩展而远离与轴承的接合到解锁位置。 轴承接合表面可以适于接合轴承并将轴承推离远离托盘。

    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.

    摘要翻译： 用于植入患者骨骼的矫形假体包括适于固定在骨中的多孔金属壳。 多孔金属壳包括适于接收骨向内生长的外表面和适于接合衬垫的内表面。 多孔金属壳从外表面到内表面是多孔的。 无孔构件可以固定到多孔金属壳上。 无孔构件可以包括从外表面延伸的刺穿构件，刺穿构件适于在植入位置穿透骨骼。 无孔构件可以包括尖钉或翅片。 在一个示例中，刺穿构件可以在与多孔金属壳的外表面的界面处限定减小的材料横截面。 刺穿构件可以适于在减小的材料横截面处断裂并从多孔金属壳体移除。
