    • An anchor for securing an implant within bone. In one embodiment, the anchor is used to aid in securing an acetabular cup within an acetabulum. The anchor may be implanted within an ischial defect of the pelvis, and is attached to an outer surface of the acetabular cup shell. The anchor is made at least in part of, and may be made entirely of, a porous metal material to facilitate the ingrowth of surrounding bone into the anchor for osseointegrating the anchor into the surrounding bone. The anchor may be secured to the acetabular shell by a screw fastener or by cement, for example. The anchor may be secured to the acetabular shell before the anchor and the acetabular shell are together implanted into the acetabulum, or the anchor may be implanted into the ischial defect, followed by seating the acetabular shell in the acetabulum and then securing the acetabular shell to the anchor.
    • 用于固定植入物在骨内的锚固件。 在一个实施例中,锚固件用于帮助将髋臼杯固定在髋臼内。 锚固体可以植入在骨盆的坐骨缺损中,并且附接到髋臼杯外壳的外表面。 锚固件至少部分地制成并且可以完全由多孔金属材料制成,以便于将周围的骨向内生长进入锚固件中,以将锚固体整合到周围的骨中。 例如,锚固件可以通过螺钉紧固件或水泥固定到髋臼壳。 在将锚固件和髋臼壳植入髋臼之前,可以将锚固件固定到髋臼壳上,或者可以将锚固件植入坐骨缺损,然后将髋臼壳放置在髋臼中,然后将髋臼壳固定到 锚点。
