摘要： A patient-specific acetabular guide can be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide includes a patient-specific engagement surface designed to be complementary and mateable with a corresponding surface of the patient's pelvic anatomy. The acetabular guide is designed during a pre-operative plan for the patient by a three-dimensional reconstruction of the anatomy of the patient using two-dimensional medical images. The patient-specific engagement surface has a first portion mateable with a portion of the acetabulum of the patient. The acetabular guide includes a guiding element that extends from the acetabular guide opposite to the first portion of engagement surface. The guiding element defines a bore designed to be oriented along an alignment axis for an acetabular implant when the acetabular guide is engaged to the acetabulum.

摘要： An acetabular cup assembly implantable at an acetabular socket (166) can include an acetabular cup (160) defining a partially spherical bone engaging surface and having a uniform thickness. A spacer (10j,10k,10m,10n) can include a body portion (170j) formed of porous metal and define a radial support surface. The porous metal can be adapted to receive bone ingrowth through interstitial space at pores defined therein. The spacer (10j,10k,10m,10n) can further comprise a piercing portion (172j) adapted to be advanced into the acetabular socket (166). The spacer (10j,10k,10m,10n) can bridge a gap defined between the acetabular socket (166) and the acetabular cup (160). Filler can be disposed between the acetabular cup (160) and the acetabular socket (166) in areas adjacent to the spacer such that the spacer and the filler collectively define a continuous support surface adapted to support the acetabular cup (160) at the bone engaging surface.

摘要： An orthopedic prosthesis (10a) for implantation into a bone of a patient includes a porous metal shell (12a) adapted to be affixed within the bone. The porous metal shell includes an outer surface (16a) adapted to receive bone ingrowth and an inner surface (14a) 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 (28) extending from the outer surface, the piercing member adapted to penetrate the bone in an implanted position. The non-porous member may include spikes (28) 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： An acetabular cup assembly implantable at an acetabular socket (166) can include an acetabular cup (160) defining a partially spherical bone engaging surface and having a uniform thickness. A spacer (10j,10k,10m,10n) can include a body portion (170j) formed of porous metal and define a radial support surface. The porous metal can be adapted to receive bone ingrowth through interstitial space at pores defined therein. The spacer (10j,10k,10m,10n) can further comprise a piercing portion (172j) adapted to be advanced into the acetabular socket (166). The spacer (10j,10k,10m,10n) can bridge a gap defined between the acetabular socket (166) and the acetabular cup (160). Filler can be disposed between the acetabular cup (160) and the acetabular socket (166) in areas adjacent to the spacer such that the spacer and the filler collectively define a continuous support surface adapted to support the acetabular cup (160) at the bone engaging surface.
