Abstract
An acetabular prosthesis having an outer member for engaging the acetabulum. The outer member has a part-spherical bearing surface terminating in a distal rim. The rim has a contour such that the portion thereof to be located between the ischium and the pubis extends distally further from an equator of the bearing surface than the contour to be implanted between the pubis and the illium and between the ischium and the illium.

An acetabular prosthesis comprising:
- an outer member for engaging the acetabulum, said outer member having a part-spherical bearing surface terminating in a distal rim, said rim having a contour such that the portion thereof to be located between the ischium and the pubis extends distally further from an equator of said bearing surface than the contour to be implanted between the pubis and the illium and between the ischium and the illium.
A prosthetic acetabular cup for securing an acetabulum comprising an inner part-spherical bearing surface and an outer peripheral rim portion which is shaped to mimic the contours of the natural shape of an acetabulum.
