ABSTRACT:
An acetabular prosthesis comprises a body 41 of plastics material defining a part-spherical socket cavity 43 surrounded by a rim 44. A flange extends outwardly from the rim 44. At 48 it inclines from the rim 44 in the direction of the body 41 and at 49 it inclines from the rim in a direction away from the body 41, while lobes 46, 47 therebetween are correspondingly curved. This arrangement provides for a considerably increased area of bone in the acetabulum to be available as a cementing surface when the prosthesis is fitted into a reamed out hip acetabulum in the special circumstances of the invention which is that the axis of socket cavity 43 extends substantially transversely with no or little anteversion.
