IMPROVED ACETABULUM PROSTHESIS

摘要

An improved acetabular prosthesis (14) is disclosed for use with a femoral head prosthesis. The acetabular prosthesis comprises a rigid cup-shaped member (28) insertable as a friction fit in the acetabulum and providing on its inside a hemispherical socket for the reception of the ball (16) of a femoral head prosthesis (12) and coated on its external surface with a layer (32) of deformable, biocompatible material which upon insertion of the prosthesis moulds itself into conformity with the surface contour of the acetabulum. Interiorly the prosthesis is provided with a wear resistant lining (30).
