An acetabular prosthesis system configured to be coupled to a surgically-prepared acetabulum includes an acetabular shell and an augment component. The augment component has an inner curved surface configured to engage the outer curved surface of the acetabular shell, an outer surface, and a slot extending through the inner curved surface of the augment component and the outer surface of the augment component. A fastener is used to couple the acetabular shell and the augment component together, extending through an aperture in the shell and the slot in the augment component.
