A hip replacement system is analysed with respect to its susceptibility to friction induced vibrations under laboratory conditions and in a pseudo-in vivo setup. The method of complex eigenvalue extraction within the framework of finite-element modelling and analysis is used to identify the geometri

Abstract
The hip is a ball and socket joint designed to bear the body mass as well as for facilitating the movement in many directions. Hip replacement is an operation to replace a natural hip joint with an artificial one. The aim of the present work is to conduct a parametric study that comprises the parameters affecting the strength of hipβjoint cement fixation (offset distance and ball diameter), in order to comeβup with the best combination for maximum strength. The results lead to recommending offset distance (3β6βmm) and ball sizes (34 and 50βmm) for maximum cement strength.

The pseudojoint cavity formed in patients undergoing total hip arthroplasty (THA) is later remodeled to synovial membrane-like tissue, which produces pseudosynovial fluid. This pseudosynovium also is an important source of matrix metalloproteinases (MMPs). As it is widely speculated that synovial fl
## Abstract The acid resistance of tantalum coated and uncoated human hip joint prostheses was studied with commercial CrCoMo acetabular cups. The samples were exposed to 10% HCl solution and the quantities of dissolved Cr, Co, and Mo were measured with protonβinduced Xβray emission (PIXE). The abs
This study is based upon observations made upon the hip joints of 12 embalmed cadavers. Windows were made into the joints and the effects of extension and flexion of the femur, produced both actively and passively, were noted. Particular attention was paid to associated movements. Use was made of x-
