,Sozialpädagogik als politisches Programm,icle related tissue reactions such as the development of foreign-body granulation tissue with or without inflammation may occur. Furthermore, due to various metabolic diseases endogenously produced deposits with simultaneously induced foreign-body tissue reactions are often observed in synovial tissue.

Tribological and Material Properties for all-Alumina THR -Convergence with Clinical Retrieval Datahe University ot Paris between Drs. Boutin, Witvoet and Sedel furthered the development and analyses ot their all-alumina THR. Beginning in 1977, they incorporated the taperlock ball design and the hemispherical alumina cups of the cemented and press-fit THR types (Fig. 1).

The Influence of the Wear Bearing Coupling on Range of Motion and Stability against Dislocation of Tfor hip arthroplasty a lengthening of performance life times of THR has become necessary. The most frequent reason for total hip prosthesis failure is the particle induced aseptic loosening , therefore lowwear bearing couples like ceramic-on-ceramic are increasingly used.

The Influence of Artificial Ageing on the Stability of Ceramic Inserts in Sandwich Acetabular Cups wear of UHMWPE was recognized as a potential source of problems. Attempts to improve on this issue were the introduction of ceramic ball heads made from high purity alumina ceramics or elimination of UHMWPE altogether by the use of hard-on-hard bearing, either metal-on-metal or ceramics-on-ceramics.
