Inner acetabular liner for a dual mobility femoral head construct

A dual mobility femoral head construct has a secure acetabular shell received within an acetabular recess formed in a pelvis. An implantable prosthetic device is implantable after a failure of an originally installed articular head insert of an acetabular cup assembly. A hemispherical liner is formed from a cast cobalt-chromium alloy for thinness and elasticity. At least three spacers are annularly displaced about an outer diameter of the hemispherical liner to define a uniform cement thickness with the secure acetabular shell. Web shaped depressions are formed circumferentially in the outer diameter of the hemispherical liner to receive cement to resist lever out forces and to secure the cement bond with the secure acetabular shell. A replacement articular head insert is then received for dual mobility rotational movement in an inner diameter of the hemispherical liner. A femoral head implant is received for articulating movement in the articular head insert.
