Summary: The implantation of hip joint endoprosthesis (EP) is one of the greatest achievements in orthopaedic surgery. At present, research is aimed at permanent fixation of EP in bone bed. Refinements of both the shape od EP and cementation techniques, with the application of autologous autotransfusion, with the educations of the treated patients, are being made to improve the quality of treatment. Uncemented EP are ussually applied in younger patients and in revision surgery. Personal expirience in use of cementless EP of patients under the 50 years of age is analysed. Reconstruction of the hip joint by implantation of EP enables overcoming of numerous problems of young persons, such as limping, difference in the leg length, painfulness, early development of degenerative changes and for some persons very important visible cosmetic problems and sexual difficulties. Application of special, tumoral, modular cementless EP which is highly differentiated surgical procedures, necessiates special technical preparations and the experiences of most distinguished centralised orthopaedic institutions. Results of treatment with other treatments possibilities in osteosarcoma, Ewing sarcoma or chondrosarcoma are analysed, as well as complication after resection of tumoral and total hip replacement. Use of the most up-to date hip EP now makes it possible to restore painlessness movability and to improve quality of life of treated patients. Completition of orthopaedic treatment, no matter how radical, maz even in objectivelz extremelz severe conditions result in good quality of life. Quality of life is good in the treated children, and also younger patients. Beetwen 407 uncemented endoprothesis, 325 (79,6%) were patzients younger than 55 years. Extremely high degree of reintegration to normal life justifz applications of endoprotheses in children and younger patients. Complications, among them infection in thje area of the endoprosthesis, are dangeres and expenssiv, both for patients and helth organisations. Patients informations greatly assist to patients concerned with the hip problem and therefore improve the quality of life and vaule of operative procedures. Limb salvage surgery can be done even during the war and post- war time. Beetwen 51 malignant bone tumours, endoprothesis was implantated in 14 of them. Diofferent modality of treatament according tp the econimical situation and the technical possibilities are justifying our efforts to have better results of the treatment with endoprothesis.

Keywords: hip, hip endoprostheses, cementless hip endoprostheses, revision surgery, autologous autotransfusion and hip endoprostheses, reaming of the medullary canal, Chiari pelvic osteotomy, hanging hip, diagnostic procedures in locomotour toumors, embolisation, angiography, osteosarcoma, Ewing sarcoma, chondrosarcoma, complications after treatment of bone tumors, treatment in the war situation, external fixators.

Research goals: To find the criteria for the treatment of differental diseases ofthe locomotor system in younger patients with imlantatedendoprosthesis in the case of degenerative disease, congenitalhip displasia, tumours or war injuries. With biomechanical consideration of load transmission, clinicalexperience of the operative implantatins techincs or applicationof the autologous autotransfusion is analysed. Together with thetheoretical investigations, the design of own cementlessendoprosthesis model is prepared, with the better shape andimplantation technics. The instrumentation for application ofthese model will be developed. The value of other ways of the treatment of bone tumours, and theinfluence on the possibilities of implantation of special,tumoral cementless endoprosthesis is considered. In the same time with the clinical experiences permanentscientific education of patients with written materials for thepersons with implanted artificial hip joint, about different lifesituations is necessary the function of new hip will be more longer.
