Abstract

In elderly patients with a low bone mineral density primary endoprosthesis shoulder joint is one of the methods of surgical treatment. Goal. Perform a historical review of the development of reverse shoulder arthroplasty (RSA) with analysis of biomechanical features of existing implants, their advantages and disadvantages to identify possible areas for further ways of improvement. Methods. Search for scientific information was performed in electronic databases PubMed, ScienceDirect, Google Scholar with a search depth of 30 years. There were selected 68 sources. Results. Unsatisfactory results after shoulder hemiarthroplasty caused in patients with severe damage to the rotator cuff and multifragmental fractures of the proximal humerus using RSA. Endoprosthesis design C. Neer replaced the implants of P. Grammont design, built on the principles: spherical glenoid component, concave support part on the humerus, the center of rotation at the level or medially of the scapular neck, proximal humerus fractures is displaced medially and distally. Medialization of the center of rotation is an
unfavorable factor that leads to loss of tension of the deltoid muscle. To eliminate this disadvantages, lateralized hemispheres have been developed, with the help of which stability is achieved, the formation of a defect of the lower edge of the scapular neck is prevented. Their size affects on the volume of movements: the smallest diameters should be used for prevention of soft tissue strain. Note that the use of RSA with a lateralized center of rotation and varus shoulder component brings biomechanics closer shoulder joint to normal anatomical features. Conclusions. The main directions of RSA improvement: conducting biomechanical research to evaluate structures endoprostheses in order to choose the optimal design; introduction of modern additive technologies that will allow to obtain porous components with increased osteointegrative properties; reduce the weight of the hemisphere; improving friction pairs

The authors retain the right of authorship of their manuscript and pass the journal the right of the first publication of this article, which automatically become available from the date of publication under the terms of Creative Commons Attribution License, which allows others to freely distribute the published manuscript with mandatory linking to authors of the original research and the first publication of this one in this journal.

Authors have the right to enter into a separate supplemental agreement on the additional non-exclusive distribution of manuscript in the form in which it was published by the journal (i.e. to put work in electronic storage of an institution or publish as a part of the book) while maintaining the reference to the first publication of the manuscript in this journal.

The editorial policy of the journal allows authors and encourages manuscript accommodation online (i.e. in storage of an institution or on the personal websites) as before submission of the manuscript to the editorial office, and during its editorial processing because it contributes to productive scientific discussion and positively affects the efficiency and dynamics of the published manuscript citation (see The Effect of Open Access).
