ABSTRACT:
An acetabular cup kit for use during hip replacement surgery includes a polar component with a socket for receiving a femoral head of a femoral prosthesis. A metal shell has a cavity which is configured for receiving the polar component therein. The metal shell also includes an annular face bounding the cavity. A metal ring is attachable with the metal shell at the annular face. The metal ring is configured to retain the polar component within the cavity when attached with the metal shell. The metal ring includes at least one secondary fixation device, such as a flange, allowing fixation of the metal ring with a pelvic bone. A plastic ring is also attachable with the metal shell at the annular face. The plastic ring is configured to retain the polar component within the cavity when attached with the metal shell.
