摘要： An acetabular cup assembly allows pre-operative or interoperative selection and securement of a bearing member within a shell member of the acetabular cup assembly, the bearing member being selected from a plurality of bearing members having different characteristics, including bearing characteristics, securement characteristics, position characteristics and orientation characteristics, so as to enable a surgeon to select those characteristics most appropriate to a particular patient, as determined by a pre-operative assessment or by an evaluation of conditions encountered at an implant site during the implant procedure, and to incorporate the desired characteristics into the acetabular cup assembly with ease and economy.

摘要： A method of securing an acetabular cup to an acetabulum so as to provide a bearing surface for a head portion of a femur includes the step of reaming a hemispherically-shaped cavity having a first radius into the acetabulum with a reamer. The reamer (50) includes a hemispherically-shaped cutting head which possesses the first radius (R A ). The method also includes the step of press fitting the acetabular cup into the cavity reamed into the acetabulum. The acetabular cup (12) includes a cup body having a substantially constant radius sidewall (26) which extends outwardly from an apex (28) to an annular rim (30). The sidewall defines an imaginary hemisphere (32) having a second radius (R C ). The second radius (R C ) is greater than the first radius (R A ). An outer face of the annular rim of the cup body defines a segmental plane (40) which intersects the imaginary hemisphere. The segmental plane is parallel to a great circle (36) of the imaginary hemisphere. The segmental plane is separated from the great circle of the imaginary hemisphere by a distance D in which 0.5 millimeters ≤ D ≥ 2.0 millimeters. A prosthetic hip assembly for replacing a natural bearing surface of an acetabulum with an artificial bearing surface for a head portion of a femur is also disclosed.
