title: [Mechanical durability characteristics of polyethylene cup in total hip arthroplasty].
abstract: The paper presents an analysis of the processes that determine the durability of the polyethylene cup of the Weller total hip prosthesis. Mechanisms of wear of the polyethylene cup have been presented. It has been inferred that the process of loosening of the polyethylene cup is a combination of plastic deformation, tribologic wear, fracture and changes of the polyethylene structure. All these occurrences are connected with reaction of bone tissue to stress and polyethylene debris.
