摘要： A prosthetic component assembly (10), such as an acetabular cup, includes a shell (12) and a bearing insert or liner (14). The shell (12) and bearing insert are configured to provide an increased congruency between the shell (12) and the bearing insert thereby decreasing the amount of motion (i.e. micro-motion) between the shell (12) and the bearing insert. In one form, increased congruency is achieved through first (30) and second (44) (inner and outer) tapers that are respectively provided on the shell (12) and the bearing insert. The outer taper (44) has first and second outer taper portions. A relationship between the first outer taper portion and the inner taper (30) provides an essentially congruent fit, while a relationship between the second taper portion and the inner taper (30) provides an interference fit. The relationships between the inner (30) and outer (44) tapers allow the bearing insert to achieve load sharing at a dome of the outer shell (12) as well as at a rim of the shell (12). The relationships between the tapers (30,44) also allow relative motion between the shell (12) and the bearing insert to be controlled. Particularly, the relationships between the tapers (30,44) allow relative motion, or micro-motion, to be uniformly controlled below previous levels reported in the range of 10 micrometers or less between the bearing insert and the shell (12).

摘要： A prosthetic device, such as an acetabular cup, includes a shell (12), a liner (14) and a bearing (16). The bearing may be coupled to the liner so as to form a bearing-liner subassembly. The shell is provided with a female taper (30) complimentary to a male taper (44) on the liner. The liner-bearing subassembly may be secured to the shell by engaging the complimentary tapers.
