Design rationale :
The CEMENTED Double Mobility DM acetabular component is a stainless steel cemented cup transposing the proven CHARNLEY cup features into a double mobility system.
The main feature of such a device being that the double mobility reduces joint bearing friction by half. The cup is lifted by a tripod dome and dimple surface to allow for an even cement mantle. Three rim flange vent holes allow excess cement escape.
