The invention provides an acetabular prosthesis comprising an outer portion having a substantally concave inner surface and a substantially convex outer surface. An inner portion within and spaced from the outer portion and having a substantially concave inner surface defining a cavity and a substantially convex outer surface. Flexible connecting means, such as vanes, connect the outer convex surface of the inner portion to the concave inner surface of the outer portion. Such an acetabular prosthesis can exhibit matched compliance between the outer portion and the patient's pelvis while the inner portion accommodates idealised rigidity for artificial articulation components.
