Abstract
A hip cup for use as an acetabular component in a hip prosthesis including a shell part having a partially convex outer surface. The shell part is insertable in a cavity having an inner surface that is substantially defined by the outer surface of a segment of a sphere. The outer surface of the shell part substantially corresponds to the outer surface of a part of an ellipsoid and has an apex. During positioning of the shell part in the cavity, the shell part has a circumferential edge contacting the longitudinal edge of the cavity, with a space formed between the inner surface of the cavity and the apex of the shell part. A tool has an end releasably attachable to the shell part and a striking end. A handle on the tool permits positioning the tool and shell part to the cavity and striking the end to enact the shell in the part in a selected position.
