| 摘要 |
<p>The invention provides an acetabular prosthesis (1) comprising: an outer portion (2) having a substantially concave inner surface (4) and a substantially convex outer surface (5); an inner portion (3) within and spaced from the outer portion (2) and having a substantially concave inner surface (6) defining a cavity (7) and a substantially convex outer surface (8); and flexible connecting means, such as vanes (9) connecting the outer convex surface (8) of the inner portion (3) to the concave inner surface (4) of the outer portion (2). Such an acetabular prosthesis can exhibit matched compliance between the outer portion (2) and the patient's pelvis while the inner portion (3) accommodates idealised rigidity for artificial articulation components. <IMAGE></p> |
