摘要：
An acetabular cup assembly for use in the replacement of a hip joint, including a shell having a substantially hemispherical outer surface and an inner surface. The inner surface includes a groove extending at least partially around the inner surface. A provisional liner is provided which is receivable within the shell, the liner including a hemispherical cavity and articulation surface for receipt of the femoral head of a femoral prosthesis, and at least one flexible tab portion which engages the groove of the shell in a snap-fit manner.
