Abstract
The artifical acetabulum is formed of an outer metal shell having an annular shoulder, an acetabular body having an annular flange seated on the shoulder and a threaded ring threaded into the shell in order to clamp the flange of the acetabular body against the shoulder of the shell. The acetabular body is constructed in an asymmetric manner with an extension to prevent dislocations of a joint head and can be rotated into precise position before tightening of the threaded ring in place.
