[New aspects in the use of artificial hip joints]

The implantation of hip joint endoprosthesis is one of the greatest achievements in orthopedic science. At present, research is aimed at permanent fixation of endoprosthesis into the bone bearing. Refinements of both endoprosthesis and cementation techniques are being made. Uncemented endoprostheses are usually applied in younger patients and in revision surgery. Personal experience in use of uncemented endoprosthesis of patients under 50 years of age is presented. Reconstruction of the hip joint by using endoprosthesis enables overcoming of numerous problems of young persons such as limping, difference in length of the lower extremities, painfulness, early development of degenerative changes and for some persons very important visible cosmetic problems and sexual difficulties. Use of the special tumor modular uncemented endoprosthesis which is a highly differentiated surgical procedure, necessitates special technical preparations and the experience of most distinguished centralized orthopedic institutions. Use of most up-to-date hip endoprosthesis now makes it possible to restore painlessness, movability and to improve the quality of life of treated patients.
