Assignee:

International Classification:

A61F 2/32

US Classification:

623 224

Abstract:

A prosthetic component assembly, such as an acetabular cup, includes a shell and a bearing insert or liner. The shell and bearing insert are configured to provide an increased congruency between the shell and the bearing insert thereby decreasing the amount of motion (i. e. micromotion) between the shell and the bearing insert. In one form, increased congruency is achieved through first and second (inner and outer) tapers that are respectively provided on the shell and the bearing insert. The outer taper has first and second outer taper portions. A relationship between the first outer taper portion and the inner provides an essentially congruent fit, while a relationship between the second taper portion and the inner taper provides an interference fit. The relationships between the inner and outer tapers allow the bearing insert to achieve load sharing at a dome of the outer shell as well as at a rim of the shell. The relationships between the tapers also allow relative motion between the shell and the bearing insert to be controlled.

Inventors:

Paul P. Lewis - Warsaw IN, US
Barry A. Schnieders - Plymouth IN, US

International Classification:

A61F 2/34

US Classification:

623 2238

Abstract:

An acetabular shell for use in a hip prosthesis is provided. The shell includes a body having an inner periphery and a convex outer periphery and defining a cavity of the body. The outer periphery has a first portion defining a hemisphere and a second portion extending from the equator of the first portion in a converging direction. The second portion forms a rim opposed to the equator. The cavity is positioned within the rim.
