INSERT FOR ACETABULAR CUP

摘要

An insert (10) for an acetabular cup (12) comprises an insertion body (18) having an external surface (19) shaped so as to be able to be coupled with a mating seating (13) of the acetabular cup (12). The insert (10) comprises at least a friction element (20) which is positioned on the external surface (19) in order to determine a predefined friction with the surface of the seating (13), so that, during use, the friction element (20) prevents the relative rotation of the insertion body (18) and the acetabular cup (12).
