<p>A hip joint prosthesis 10 includes a resilient element (artificial acetabulum) 16 which is positioned between innominate bone and femoral head 12. The resilient element 16 has a generally cup-shaped configuration, with a generally hemispherical convex outer engagement surface 18 for engaging innominate bone and with a generally hemispherical concave inner engagement surface configured as a wear resistant articulation surface for articulation with femoral head 12. The resilient element 16 has a non-linear, half-bell-shaped stress strain relationship.</p> |
