HIP JOINT PROTHESIS

摘要

A hip joint prosthesis has a metallic shell (1) and an acetabular insert (2) with a spherical recess (3), as well as an intermediate element (4) made of plastics arranged between the shell (1) and the acetabular insert (2). To prevent osteolysis, the intermediate element (4) is made of an upper part (5) and a lower part (6) which can be linked to each other and the acetabular insert (2) is anchored between the upper part (5) and the lower part (6).
