ASEPTIC LOOSENING OF THE ACETABULAR COMPONENT IN CEMENTLESS HIP ARTHROPLASTY

The review presents the analysis of both domestic and foreign literature devoted to such complication of hip replacement, as the aseptic loosening of cementlessacetabular component. This complication is becoming increasingly important in connection with the steady increase in the number of implantations of endoprostheses of large joints. Worldwide trends towards the use of cementless products. Among the main reasons leading to the loosening of the acetabular components of the implants are: the imperfection of the design, increased the coefficient of friction in the node mobility, the size of the head, tissue reaction to the wear products (metal, ceramic, polyethylene), mistakes in the operation's technique, osteoporosis.
