[A concept of need and construction of a hip joint prosthesis with isolation of the friction point from the tissue].
The paper presents data available in the literature and the author's own data on the causes of bone tissue resolution around endoprostheses and on the occurrence of their aseptic instability. The author's own clinical data on 546 operations and follow-ups up to 16 years are strong evidence and his experimental findings are unique in the number of animals operated on and follow-up periods. The material was examined roentgenologically, morphologically, spectroscopically and the mineral content of bone tissue microstructures were determined. With the methods applied, the author clearly shows the role of tissue metallosis in the occurrence of aseptic instability of prosthesis. The author presents two up-to-day constructions of the total-type endoprostheses with the friction point isolated from tissue. The prostheses are accessible for manufacture at the modern enterprises and require no materials in short supply.
