Abstract:
1. A kit of acetabular components for assembling an acetabular joint prosthesis including a shell component and a bearing component disposed in the shell, the kit comprising: a shell component having an external surface shaped for engagement with an acetabulum and an internal surface defining an internal cavity and a shell engagement mechanism; a first bearing component having an external surface dimensioned for receipt within the internal cavity of the shell component, the external surface of the first bearing component defining a first bearing engagement mechanism, the first bearing engagement mechanism engageable with the shell engagement mechanism of the shell component to secure the first bearing component at least partially within the internal cavity of the shell component; a conversion ring having a sidewall defining an outer surface and an inner surface and extending axially from a first end to a second end, the outer surface defining a first conversion ring engagement mechanism, the first conversion ring engagement mechanism releasably engageable with the shell engagement mechanism of the shell component, the inner surface of the conversion ring defining a second conversion ring engagement mechanism; a second bearing component having an external surface dimensioned for receipt within the internal cavity of the shell component and within the conversion ring, the external surface of the second bearing component defining a second bearing engagement mechanism releasably engageable with the second conversion ring engagement mechanism of the conversion ring, wherein the conversion ring is resiliently collapsible upon insertion into the shell component to engage the first conversion ring engagement mechanism of the conversion ring with the shell engagement mechanism of the shell component.
