Abstract

Abstract. Development of modern arthroplasty in Ukraine, according to Academician of the National Academy of Sciences and the National Academy of Medical Sciences of Ukraine O.O. Korzh, began thanks to the activities of O.Ye. Loskutov (Dnipro) who managed to create his own Ukrainian endoprosthesis on the basis of the relevant enterprises of the city and establish specialized endoprosthetic clinic. The article reflects 30 years of experience in the de velopment of national arthroplasty. To solve the problem of development of national arthroplasty, the Orthopedic Joint Replacement initiative program (ORTEN) has been developed. For this purpose, an intersectoral problem laboratory was created which united the efforts of the scientists of different specialties and key enterprises of the Dnipro region. Biomechanical researches on native studying of mechanical properties of articular sites of bones have been carried out through mathematical modeling. Estimation of a stress-strain state of subchondral, spongy bone and various sites of long bones in "bone-implant" system has been carried out in order to define primary and secondary stability of different kinds of the developed im plants. Numerous biochemical, histochemical and toxicological studies on laboratory animals have been performed to evaluate the effects of implant materials and the developed types of protective coatings. X-ray morphometric and anthropometric studies of articular surfaces of bones were used in various pathologies of the joints for the development of implants; technical methods were used to assess the mechanical properties of implants under load. The developed designs of endoprostheses have passed certification and have been brought into pro duction. Clinical introduction of domestic endoprostheses was implemented in the Ukraine’s first specialized department of joint arthroplasty which was opened in Dnipro. The developed methods and methodological support for the use of the elaborated designs of endoprostheses allowed to organize the basic training of Ukrainian specialists through the Basic Course of Prof. O.Ye. Loskutov which was taken by almost 350 Ukrainian orthopedists.
