[Secondary and tertiary endoprosthesis of the hip joint.].
The authors analyze mechanical and biological causes of loosening of cemented total endoprosthesis of the hip joint. They reflect on the "most suitable" time of reoperation, based on clinical experience and the X-ray finding. The authors investigated on account of loosening of the first and second endoprosthesis of the hip joint resp. a group of 28 patients. They present an account of their experience with some new non-cemented types of prostheses during primary or secondary revisions of total prostheses of the hip joint. Key words: total endoprosthesis of the hip joint, aseptic loosening, reimplantation of a total endoprosthesis of the hip joint, secondary and tertiary endoprosthesis of the hip joint.
