Multi-component joint prosthesis with increased wall flexibility facilitating component assembly

摘要

Multi-component joint prosthesis including first and second components for being assembled together and the assembly of which requires the application of assembly forces, e.g. a hip joint prosthesis including an acetabular cup and plastic bearing liner for being assembled together and wherein such assembly requires the application of assembly forces. One or both of the components being a segmented open shell including a wall having a major load supporting segment resisting the assembly force removed which increases the flexibility of the wall and facilitates assembly of the components, e.g. in one hip prosthesis embodiment an inferior segment of the wall of each component is removed to increase the flexibility of the wall and facilitate the assembly of the acetabular cup and plastic bearing liner.
