ARTIFICIAL ACETABULAR CUP

摘要

The hip joint socket is provided with a peripheral edge or flange in which a plurality of bores are formed. Each bore narrows conically from one side of the peripheral edge towards the free surface of the socket to provide outflow paths for excess bone cement which is displaced during implanting of the socket in a pelvis. The construction in the bores also permits the excess cement to harden into a rivet-like plug to increase the securement of the hip joint socket in the cement bed.
