Hip prosthesis for artificial hip joints

摘要

The invention relates to a hip joint prosthesis comprising a ceramic inner sliding cup ( 1 ) that, on its outside, is surrounded by a plastic covering ( 2 ), for inserting into an outer metal cup ( 6 ) or for directly implanting with the aid of bone cement. A ball head, which is mounted on a shaft, articulates inside the inner sliding cup ( 1 ), and said shaft can be anchored inside the femur. In order to increase the strength with regard to tilting and turning, the exterior of the sliding cup ( 1 ) is provided with a structuring.
